Acknowledgement

A special thank you to Mr. Sriyantha (Simon) Senaratna, Precedent Partner, Simon & Associates, Attorney’s-at-Law and Notary Public, Sri Lanka, who was the Managing Director of Walkers Tours, 50 years ago when they entered the hotel industry. He provided valuable historic information about the beginning of a remarkable journey of a hotel company, for this article.

Cinnamon Hotel Brand

John Keells Group operated their hotel management company under different brand names. In 1970s as Walkers Tours Hotels, in 1980s as Hotel Management & Marketing Services Limited, and in 1990s as John Keells Hotels. In the year 2005, they rebranded their hotel chain as Cinnamon. In 2023, Cinnamon is the largest hotel company in Sri Lanka. They also have four hotels in the Maldives. With the opening of their 16th hotel – Cinnamon Life Colombo, the company will have a stock of 3,288 hotel bedrooms in Sri Lanka and The Maldives. Today, both in terms of the quality of the hotels and the quantity of the room stock, Cinnamon is arguably the greatest hotel company in Sri Lanka.

Generations of board members and professional hoteliers have contributed to this remarkable journey, having many unprecedented successes. In spite of various macro level challenges such as corruption, political instability and the 26-year civil war in Sri Lanka from 1983 to 2009, Walkers Tours/John Keells hotels managed to survive and progress. At the end of the day, it is still important to understand the humble beginning of this hotel company and appreciate the pioneers who commenced that amazing journey, 50 years ago…

How Did Everything Start in 1973?

After reading my recent episodes of ‘Confessions of a Global Gypsy’ dedicated to my time at The Lodge and The Village, Habarana, I received more than the normal volume of reader’s mail. One was a long e-mail from a person with whom I had no contact for 40 years. This person, Sriyantha (Simon) Senaratna was the Managing Director of Walkers Tours when I joined them in 1977.

He wrote to me: “Chandana, this is a voice from the past. I have been following with great interest your series of articles on your life in the leisure industry appearing in the Sunday Island. Firstly, I want to thank you very much for the kind references that you have made about me personally in some of your articles. I was greatly overjoyed, last Sunday when you mentioned the name of Somaratna Silva as the architect of Habarana Village. I would like to mention the background to Habarana Village, which almost did not happen.” After exchanging a couple of further e-mails, he kindly agreed to collaborate with me in writing the following question and answer section of this article. Thank you, Mr. Senaratna!

As a US trained lawyer, how did you end up in the Tourism and Hotel Industry, over 50 years ago?

Answer: In 1970 I returned to Sri Lanka from the US and became an employee of Mr. N. S. O. Mendis, one of the great corporate leaders in Ceylon of that period, owning Mackwoods, Mackinnons, Delmege and the later acquisition, Walkers. He appointed me to the Board of Management to overlook the legal affairs of the behemoth Walkers & Sons. He never stepped into any of his acquisitions, but let the boards run them and report to him directly from time to time at his residence.

At one of the meetings, he mentioned to me that Walkers had a small travel company called Walkers Tours & Travels Limited, and whether I could look it over, in addition to my other duties. I had no idea of the Travel Industry, but he was a marvellous judge of people and he thought that I could do something. So, at the age of 30, I became the Managing Director at Walkers Tours.

How did Walkers Tours & Travels Limited operate in the early 1970s?

They were handling two large charter operations — Tjaereborg Rejser from Denmark and Neckermann from West Germany. I studied the statistics and found out that the profits were razor thin. The greater portion of money was made by the hotels. You will recall that all these groups went on a week-long round trip, which usually included a night in Kandy, a night in Polonnaruwa/Sigiriya and another night in Annuradhapura. I was of the view, if we acquired three nights of the round trip, we would be doing well.

How was the location of Habarana chosen to build the first hotel project of Walkers Tours — The Village?

I felt that the best central location was Habarana, which was the cross road to all these historic attractions in the Cultural Triangle. I suggested to Adrian Wijemanne, the Chairman of the Board of Management, that Walkers build a hotel at Habarana, which would result in Walkers Tour’s profits increasin dramatically. We put forward a proposition to Mr. Mendis who accepted it. I was happy that my ‘gut-feeling’ was accepted by my superiors, at that time.

Thereafter Adrian, Neville Arnolda, Norman Impett and myself went to Habarana to see whether there was a suitable site. After a fruitless day of searching, we returned. After a few days Adrian, who was by then a firm believer in the idea of a hotel in Habarana, suggested that he and I meet the land officials at the Anuradhapura Kachcheri. In his work as a civil servant, he had many dealings with the Anuradhapua Kachcheri.

We met the Chief Clerk at the Kachcheri whom he knew to be a very experienced officer by the name of Perera. He immediately pulled out the one inch survey map of the area, after we advised him of the purpose of our visit. He studied the map for a few minutes, looked up and said, “I have found the ideal place for you at Habarana!”

We were quite surprised, but he said, “Let me come with you to show you the site.” So, when we came to the Habarana junction, we turned right towards Sigiriya and about 200 yards from the junction he asked us to stop the car. We looked around, it was an impenetrable jungle.

He got the help of some villagers and he took us about 200 yards into the jungle and suddenly we were looking at the Habarana Lake. Both Adrian and I looked at each other and smiled. We knew we found our site. The Government gave us 50 acres for 50 years. That was the beginning of Walkers Tours Hotels.

Who originated the concept for The Village Habarana?

Soon after we returned from Habarana to Colombo I immediately contacted Somaratna Silva (Soma) and discussed it with him. Soma was a very close friend of our family and I was his Power-of-Attorney holder whenever he was out of the country. He and I went back to the site and he identified what needed to be done. A few weeks later he came up with the concept of the Village. Mr. Mendis agreed.

Believe it or not, Soma was not a qualified architect, so there are no drawings of the village signed by him. He was the Sri Lankan representative for a large pharmaceutical group, a part of the Heineken Beer empire. In Amsterdam he followed his life’s passion of architecture and went through his training in architecture. When he came back to Sri Lanka, he showed me some of the houses he had constructed for his friends and I was deeply impressed by the concepts and the innovative use of space. In fact, the house I am living in today was designed by Soma, but for purposes of obtaining approval, all his buildings including Habarana Village and Sigiriya Village were signed by local architects.

How did the Ceylon Tourist Board react to The Village Habarana proposal?

Mr. Mendis agreed with Soma’s plans and the drawings. I took those to the Ceylon Tourist Board (CTB) to get their approval. The Development Director at CTB took a look at the drawings and said “What is this? This is not a hotel! I cannot approve this!” As you will recall at that time, the concept of a hotel was a brick-and-mortar structure with a central front office, dining room and bar. That is what he expected. Then I met with M. Y. M. Thahir, the Director General and Dharmasiri Senannayake the Chairman of CTB to convince them of this new concept. Fortunately, after several days they accepted. We commenced the project which was called ‘Habarana Walkinn’.

Who else made significant contributions to The Village Habarana project?

The interior décor of each of 60 initial cottages was done by Chole de Soysa, the wife of our Chairman A. C. H. De Soysa who had just retired as the first Chairman of the CTB. The gardens were landscaped by Bevis Bawa, and Lucky Senanayake did a magnificent mural in the lobby. Then came the choice of a manager. Soma, who had an unerring eye for people, suggested Bobby Adams, whom he had met as the Catering Manager at Queens Hotel in Kandy in 1973.

How and when did John Keells Company get involved in The Village Habarana project?

Meanwhile Mr. Mendis called me one day and said, I am selling Walkers Tours to John Keells, who were then exploring the possibility of entering the tourism sector. They started with Walkers Tours and I joined their main board. With that, Walkers Tours commenced The Village project in 1973 and joined the hotel industry with optimism and ambition to expand quickly.

When I put forward the name of Bobby Adams as the hotel opening Manager for The Village, the board, particularly David Blackler and Mark Bostock objected, saying that Bobby had no experience as a manager of a hotel, but I stood my ground and the rest is history. As you know Chandana, Bobby progressed very well.

When I was working at The Village and The Lodge in the mid-1980s, both hotels had a few weekly buffet dinners, which I heard that you were not keen about. Is that a fact?

Yes, when Habarana Village opened in 1976, I insisted that there will be no buffets whatsoever! Each meal was a sit-down meal. This was equally so when we opened Sigiriya Village. As weekly buffets were so common in all city, resort and roundtrip hotels in Sri Lanka, I wanted The Village to be different and unique, not only in its concept and design, but also in its products and services.

‘No buffet’ policy was not popular with the restaurant staff as you can imagine. When I sat for meals, it sometimes arrived late… perhaps a subtle message to me!! Of course, I noted but let it pass. After I left the company, I believe that policy was changed.

What are the other hotel projects you became involved in when you were the Managing Director of Walkers Tours?

We started with Habarana Village and just before its opening, Dr. Neville Fernando approached me to manage Hotel Swanee. After that, we took over another hotel in the same area called Dulmini owned by a local businessman. Thereafter, the film idol Gamini Fonseka approached me to manage his Sanasuma Hotel in Weerawila. Finally, before I left, we took over Hotel Ceysands owned by Lalith Kotalawela. These were the hotels under my purview in my time at Walkers Tours.

When, why and how did you become a competitor to Walkers Tours / John Keells?

A few years later, in 1979, I left John Keells as I was not in agreement with the manner in which they wished to expand the industry. I resigned and formed Gemini Tours and went on to build Sigiriya Village, which to me is a more classic example of Soma’s ability, where once again Bevis Bawa did marvels with the garden and Lucky Senanayake produced another magnificent mural in the lobby, with the interior décor of the rooms being attended to by Chloe de Soysa.

Before leaving the leisure industry during the time of the LTTE civil war, I also became one of the first Sri Lankans to invest in the Maldives, which I realised at that time was going to be an important tourist destination. When I left the industry on the invitation to be a partner of the long-established law firm D. L. & F. de Sarams, I really was going back to my first love, Law. When I left de Sarams about 29 years ago, I set up my own law firm of ‘Simon and Associates,’ where I still work, leading a set of marvellous lawyers and chartered secretaries, who handle over 400 client companies.

Do you have any other concluding comments?

Yes. In conclusion, I must mention Chandana, that when the Sigiriya Village project was nearing completion in 1980, having already become familiar with your ability and talents, I got Soma to approach you with an offer to be the hotel opening Manager of the Sigiriya Village. With 20/20 hindsight, I believe you made the correct decision by not accepting our offer, because as I see it, you blossomed under John Keells, and thereafter you had a fantastic global career. Congratulations, Chandana! I look forward to reading your column every Sunday.

Retirement age for judges: Innovation and policy

Published

on

I. The Constitutional Context

Independence of the judiciary is, without question, an essential element of a functioning democracy. In recognition of this, ample provision is made in the highest law of our country, the Constitution, to engender an environment in which the courts are able to fulfil their public responsibility with total acceptance.

As part of this protective apparatus, judges of the Supreme Court and the Court of Appeal are assured of security of tenure by the provision that “they shall not be removed except by an order of the President made after an address of Parliament supported by a majority of the total number of members of Parliament, (including those not present), has been presented to the President for such removal on the ground of proved misbehaviour or incapacity”[Article 107(2)]. Since this assurance holds good for the entirety of tenure, it follows that the age of retirement should be defined with certainty. This is done by the Constitution itself by the provision that “the age of retirement of judges of the Supreme Court shall be 65 years and of judges of the Court of Appeal shall be 63 years”[Article 107(5)].

II. A Proposal for Reform

This provision has been in force ever since the commencement of the Constitution. Significant public interest, therefore, has been aroused by the lead story in a newspaper, Anidda of 13 March, that the government is proposing to extend the term of office of judges of the Supreme Court and the Court of Appeal by a period of two years.

This proposal, if indeed it reflects the thinking of the government, is deeply disturbing from the standpoint of policy, and gives rise to grave consequences. The courts operating at the apex of the judicial structure are called upon to do justice between citizens and also between the state and members of the public. It is an indispensable principle governing the administration of justice that not the slightest shadow of doubt should arise in the public mind regarding the absolute objectivity and impartiality with which the courts approach this task.

What is proposed, if the newspaper report is authentic, is to confer on judges of two particular courts, the Supreme Court and the Court of Appeal, a substantial benefit or advantage in the form of extension of their years of service. The question is whether the implications of this initiative are healthy for the administration of justice.

III. Governing Considerations of Policy

What is at stake is a principle intuitively identified as a pillar of justice.

Reflecting firm convictions, the legal antecedents reiterate the established position with remarkable emphasis. The classical exposition of the seminal standard is, of course, the pronouncement by Lord Hewart: “It is not merely of some importance, but is of fundamental importance that justice should not only be done, but should manifestly and undoubtedly be seen to be done”. (Rex v. Sussex Justices, ex parte McCarthy). The underlying principle is that perception is no less important than reality. The mere appearance of partiality has been held to vitiate proceedings: Dissanayake v. Kaleel. In particular, reasonableness of apprehension in the mind of the parties to litigation is critical: Ranjit Thakur v. Union of India, a reasonable likelihood of bias being necessarily fatal (Manak Lal v. Prem Chaud Singhvi).

The overriding factor is unshaken public confidence in the judiciary: State of West Bengal v. Shivananda Pathak. The decision must be “demonstrably” (Saleem Marsoof J.) fair. The Bar Association of Sri Lanka has rightly declared: “The authority of the judiciary ultimately depends on the trust reposed in it by the people, which is sustained only when justice is administered in a visibly fair manner”.

Credibility is paramount in this regard. “Justice has to be seen to be believed” (J.B. Morton). Legality of the outcome is not decisive; process is of equal consequence. Judicial decisions, then, must withstand public scrutiny, not merely legal technicality: Mark Fernando J. in the Jana Ghosha case. Conceived as continuing vitality of natural justice principles, these are integral to justice itself: Samarawickrema J. in Fernando v. Attorney General. Institutional integrity depends on eliminating even the appearance of partiality (Mandal Vikas Nigam Ltd. v. Girja Shankar Pant), and “open justice is the cornerstone of our judicial system”: (Sahara India Real Estate Corporation Ltd. v. SEBI).

IV. Practical Constraints

Apart from these compelling considerations of policy, there are practical aspects which call for serious consideration. The effect of the proposal is that, among all judges operating at different levels in the judicature of Sri Lanka, judges of the Supreme Court and the Court of Appeal only, to the exclusion of all other judges, are singled out as the beneficiaries of the proposal. An inevitable result is that High Court and District Judges and Magistrates will find their avenues of promotion seriously impeded by the unexpected lengthening of the periods of service of currently serving judges in the two apex courts. Consequently, they will be required to retire at a point of time appreciably earlier than they had anticipated to relinquish judicial office because the prospect of promotion to higher courts, entailing higher age limits for retirement, is precipitately withdrawn. Some degree of demotivation, arising from denial of legitimate expectation, is therefore to be expected.

A possible response to this obvious problem is a decision to make the two-year extension applicable to all judicial officers, rather than confining it to judges of the two highest courts. This would solve the problem of disillusionment at lower levels of the judiciary, but other issues, clearly serious in their impact, will naturally arise.

Public service structures, to be equitable and effective, must be founded on principles of non-discrimination in respect of service conditions and related matters. Arbitrary or invidious treatment is destructive of this purpose. In determining the age of retirement of judges of the Supreme Court and the Court of Appeal, some attention has been properly paid to balance and consistency. The age of retirement of a Supreme Court judge is on par with that applicable to university professors and academic staff in the higher education system. They all retire at 65 years. Members of the public service, generally, retire at 60. Medical specialists retire at 63, with the possibility of extension in special circumstances to 65. The age of retirement for High Court Judges is 61, and for Magistrates and District Judges 60. It may be noted that the policy change in 2022 aimed at specifically addressing the issue of uniformity and compatibility.

If, then, an attempt is made to carve out an ad hoc principle strictly limited to judicial officers, not admitting of a self-evident rationale, the question would inevitably arise whether this is fair by other categories of the public service and whether the latter would not entertain a justifiable sense of grievance.

This is not merely a moral or ethical issue relating to motivation and fulfillment within the public service, but it could potentially give rise to critical legal issues. It is certainly arguable that the proposed course of action represents an infringement of the postulate of equality of treatment, and non-discrimination, enshrined in Article 12(1) of the Constitution.

There would, as well, be the awkward situation that this issue, almost certain to be raised, would then have to be adjudicated upon by the Supreme Court, itself the direct and exclusive beneficiary of the impugned measure.

V. Piecemeal Amendment or an Overall Approach?

If innovation on these lines is contemplated, would it not be desirable to take up the issue as part of the new Constitution, which the government has pledged to formulate and enact, rather than as a piecemeal amendment at this moment to the existing Constitution? After all, Chapter XV, dealing with the Judiciary, contains provisions interlinked with other salient features of the Constitution, and an integrated approach would seem preferable.

VI. Conclusion

In sum, then, it is submitted that the proposed change is injurious to the institutional integrity of the judiciary and to the prestige and stature of judges, and that it should not be implemented without full consideration of all the issues involved.

Ranked 134th in Happiness: Rethinking Sri Lanka’s development through happiness, youth wellbeing and resilience

Published

on

In recent years, Sri Lanka has experienced a succession of overlapping challenges that have tested its resilience. Cyclone Ditwah struck Sri Lanka in November last year, significantly disrupting the normal lives of its citizens. The infrastructure damage is much more serious than the tsunami. According to World Bank reports and preliminary estimates, the losses amounted to approximately US$ 4.1 billion, nearly 4 per cent of the country’s Gross Domestic Product. Before taking a break from that, the emerging crisis in the Middle East has once again raised concerns about potential economic repercussions. In particular, those already affected by disasters such as Cyclone Ditwah risk falling “from the frying pan into the fire,” facing multiple hardships simultaneously. Currently, we see fuel prices rising, four-day workweeks, a higher cost of living, increased pressure on household incomes, and a reduction in the overall standard of living for ordinary citizens. It would certainly affect people’s happiness. As human beings, we naturally aspire to live happy and fulfilling lives. At a time when the world is increasingly talking about happiness and wellbeing, the World Happiness Report provides a useful way of looking at how countries are doing. The World Happiness Report discusses global well-being and offers strategies to improve it. The report is produced annually with contributions from the University of Oxford’s Wellbeing Research Centre, Gallup, the UN Sustainable Development Solutions Network, and other stakeholders. There are many variables taken into consideration for the index, including the core measure (Cantril Ladder) and six explanatory variables (GDP per Capita ,Social Support,Healthy Life Expectancy,Freedom to Make Life Choices,Generosity,Perceptions of Corruption), with a final comparison.

According to the recently published World Happiness Report 2026, Sri Lanka ranks 134th out of 147 nations. As per the report, this is the first time that Sri Lanka has suffered such a decline. Sri Lanka currently trails behind most of its South Asian neighbours in the happiness index. The World Happiness Report 2026 attributes Sri Lanka’s low ranking (134th) to a combination of persistent economic struggles, social challenges, and modern pressures on younger generations. The 2026 report specifically noted that excessive social media use is a growing factor contributing to declining life satisfaction among young people globally, including in Sri Lanka. This calls for greater vigilance and careful reflection. These concerns should be examined alongside key observations, particularly in the context of education reforms in Sri Lanka, which must look beyond their immediate scope and engage more meaningfully with the country’s future.

In recent years, a series of events has triggered political upheaval in countries such as Nepal, characterised by widespread protests, government collapse, and the emergence of interim administration. Most reports and news outlets described this as “Gen Z protests.” First, we need to understand what Generation Z is and its key attributes. Born between 1997 and 2012, Generation Z represents the first truly “digital native” generation—raised not just with the internet, but immersed in it. Their lives revolve around digital ecosystems: TikTok sets cultural trends, Instagram fuels discovery, YouTube delivers learning, and WhatsApp sustains peer communities. This constant, feed-driven engagement shapes not only how they consume content but how they think, act, and spend. Tech-savvy and socially aware, Gen Z holds brands to a higher standard. For them, authenticity, transparency, and accountability—especially on environmental and ethical issues—aren’t marketing tools; they’re baseline expectations. We can also observe instances of them becoming unnecessarily arrogant in making quick decisions and becoming tools of some harmful anti-social ideological groups. However, we must understand that any generation should have proper education about certain aspects of the normal world, such as respecting others, listening to others, and living well. More interestingly, a global survey by the McKinsey Health Institute, covering 42,083 people across 26 countries, finds that Gen Z reports poorer mental health than older cohorts and is more likely to perceive social media as harmful.

Youth health behaviour in Sri Lanka reveals growing concerns in mental health and wellbeing. Around 18% of youth (here, school-going adolescents aged 13-17) experience depression, 22.4% feel lonely, and 11.9% struggle with sleep due to worry, with issues rising alongside digital exposure. Suicide-related risks are significant, with notable proportions reporting thoughts, plans, and attempts, particularly among females. Bullying remains a significant concern, particularly among males, with cyberbullying emerging as a notable issue. At the same time, substance use is increasing, including tobacco, smokeless tobacco, and e-cigarettes. These trends highlight the urgent need for targeted interventions to support youth mental health, resilience, and healthier behavioural outcomes in Sri Lanka. We need to create a forum in Sri Lanka to keep young people informed about this. Sri Lanka can designate a date (like April 25th) as a National Youth Empowerment Day to strengthen youth mental health and suicide prevention efforts. This should be supported by a comprehensive, multi-sectoral strategy aligned with basic global guidelines. Key priorities include school-based emotional learning, counselling services, and mental health training for teachers and parents. Strengthening data systems, reducing access to harmful means, and promoting responsible media reporting are essential. Empowering families and communities through awareness and digital tools will ensure this day becomes a meaningful national call to action.

As discussed earlier, Sri Lanka must carefully understand and respond to the challenges arising from its ongoing changes. Sri Lanka should establish an immediate task force comprising responsible stakeholders to engage in discussions on ongoing concerns. Recognising that it is not a comprehensive solution, the World Happiness Index can nevertheless act as an important indicator in guiding a paradigm shift in how we approach education and economic development. For a country seeking to reposition itself globally, Sri Lanka must adopt stronger, more effective strategies across multiple sectors. Building a resilient and prosperous future requires sound policymaking and clear strategic direction.

Hidden diversity in Sri Lanka’s killifish revealed: New study reshapes understanding of island’s freshwater biodiversity

Published

on

Aplocheilus parvus

A groundbreaking new study led by an international team of scientists, including Sri Lankan researcher Tharindu Ranasinghe, has uncovered striking genetic distinctions in two closely related killifish species—reshaping long-standing assumptions about freshwater biodiversity shared between Sri Lanka and India.

Published recently in Zootaxa, the research brings together leading ichthyologists such as Hiranya Sudasinghe, Madhava Meegaskumbura, Neelesh Dahanukar and Rajeev Raghavan, alongside other regional experts, highlighting a growing South Asian collaboration in biodiversity science.

For decades, scientists debated whether Aplocheilus blockii and Aplocheilus parvus were in fact the same species. But the new genetic analysis confirms they are “distinct, reciprocally monophyletic sister species,” providing long-awaited clarity to their taxonomic identity.

Speaking to The Island, Ranasinghe said the findings underscore the hidden complexity of Sri Lanka’s freshwater ecosystems.

“What appears superficially similar can be genetically very different,” he noted. “Our study shows that even widespread, common-looking species can hold deep evolutionary histories that we are only now beginning to understand.”

A tale of two fishes

The study reveals that Aplocheilus blockii is restricted to peninsular India, while Aplocheilus parvus occurs both in southern India and across Sri Lanka’s lowland wetlands.

Despite their close relationship, the two species show clear genetic separation, with a measurable “genetic gap” distinguishing them. Subtle physical differences—such as the pattern of iridescent scales—also help scientists tell them apart.

Co-author Sudasinghe, who has led several landmark studies on Sri Lankan freshwater fishes, noted that such integrative approaches combining genetics and morphology are redefining taxonomy in the region.

Echoes of ancient land bridges

The findings also shed light on the ancient biogeographic links between Sri Lanka and India.

Scientists believe that during periods of low sea levels in the past, the two landmasses were connected by the now-submerged Palk Isthmus, allowing freshwater species to move between them.

Later, rising seas severed this connection, isolating populations and driving genetic divergence.

“These fishes likely dispersed between India and Sri Lanka when the land bridge existed,” Ranasinghe said. “Subsequent isolation has resulted in the patterns of genetic structure we see today.”

Meegaskumbura emphasised that such patterns are increasingly being observed across multiple freshwater fish groups in Sri Lanka, pointing to a shared evolutionary history shaped by geography and climate.

A deeper genetic divide

One of the study’s most striking findings is that Sri Lankan populations of A. parvus are genetically distinct from those in India, with no shared haplotypes between the two regions.

Dahanukar explained that this level of differentiation, despite relatively recent geological separation, highlights how quickly freshwater species can diverge when isolated.

Meanwhile, Raghavan pointed out that these findings reinforce the importance of conserving habitats across both countries, as each region harbours unique genetic diversity.

Implications for conservation

The study carries important implications for conservation, particularly in a country like Sri Lanka where freshwater ecosystems are under increasing pressure from development, pollution, and climate change.

Ranasinghe stressed that understanding genetic diversity is key to protecting species effectively.

“If we treat all populations as identical, we risk losing unique genetic lineages,” he warned. “Conservation planning must recognise these hidden differences.”

Sri Lanka is already recognised as a global biodiversity hotspot, but studies like this suggest that its biological richness may be even greater than previously thought.

A broader scientific shift

The research also contributes to a growing body of work by scientists such as Sudasinghe and Meegaskumbura, challenging traditional assumptions about species distributions in the region.

Earlier studies often assumed that many freshwater fish species were shared uniformly between India and Sri Lanka. However, modern genetic tools are revealing a far more complex picture—one shaped by ancient geography, climatic shifts, and evolutionary processes.

“We are moving from a simplistic view of biodiversity to a much more nuanced understanding,” Ranasinghe said. “And Sri Lanka is proving to be a fascinating natural laboratory for this kind of research.”

Looking ahead

The researchers emphasise that much remains to be explored, with several freshwater fish groups in Sri Lanka still poorly understood at the genetic level.

For Sri Lanka, the message is clear: beneath its rivers, tanks, and wetlands lies a largely untapped reservoir of evolutionary history.

As Ranasinghe puts it:

“Every stream could hold a story of millions of years in the making. We are only just beginning to read them.”
