ABC

I have always believed that anyone working as an expatriate in another country must invest time to research, understand, and respect the ‘ABC’ of the host nation. My ‘ABC x 2’ model encompasses six elements about the local population:

Attitudes

Aspirations

Beliefs

Behaviours

Culture

Customs.

Fully understanding the ‘ABC’ of Guyana, respecting it, and adjusting my actions, reactions, and communication accordingly became my primary focus as I settled into my new role in South America. Based on my previous international experience, I knew that ‘ABC’ would be the key to my success as General Manager of both the Guyana Pegasus Hotel and Timberhead Eco Resort.

No matter how much effort I put into quickly grasping the ‘ABC’ of Guyana during the orientation period of my new job, I soon realised that fully understanding about a host country is a continuous learning process. My education about Guyana never ceased, and I continue to gather valuable and often fascinating insights daily.

Phagwah

Early in my tenure, I developed an excellent relationship with Maniram ‘Mani’ Prashad, the only local Board Director of the hotel’s owning company. Mani represented the Government of Guyana, which held a 5% stake in the business, while my employer – the UK-based Trust House Forte owned the remaining 95%. Mani treated me like a friend and brother, which proved invaluable.

During my first month, Mani called me one weekend, coinciding with a full moon day. “Chandi, are you free to join me for the main Phagwah celebration in the country?” he asked. Not knowing much about the event, I agreed, recognising it as an excellent public relations opportunity. A quick bit of research informed me that Phagwah, also known as Holi, is a Hindu festival celebrating the arrival of spring, good harvests, and the Hindu New Year.

When Mani arrived at the hotel entrance to pick me up, he burst into laughter. I was dressed in my usual work attire: a full suit, tie, and pocket handkerchief. “Hey, Chandi, coming from South Asia, I assumed you’d know what to expect at a Phagwah celebration!” he exclaimed. Seeing my confusion, he added, “Please change into casual clothes, preferably jeans and old shoes. This is a festival of singing, dancing, and throwing coloured powder and water. Some will even have water guns filled with coloured liquid to spray on us!”

As we drove to the city centre, Mani elaborated further. “Phagwah is a popular Hindu event celebrated as the Festival of Colours, Love, and Spring. It honours the eternal and divine love of Radha and Krishna.” No sooner had we arrived than we were sprayed with pink water by a cabinet minister and other important citizens. Within minutes, Mani and I were covered in a kaleidoscope of colours. It was a joyous and unforgettable introduction to the cultural vibrancy of Guyana.

Easter Kites

The Monday following Phagwah was Easter Monday, a public holiday. During my routine morning walk around the property, when I went to the rooftop I noticed a lively crowd gathered outside the hotel fence along the nearby seawall. Food trucks, music, and families preparing to fly kites created a festive atmosphere. Intrigued, I ventured out to blend with the locals, who seemed genuinely happy to have me among them.

I learned that kite flying is a significant Easter tradition in Guyana, symbolising the resurrection of Christ. Families and communities gather in open spaces, and the skies were filled with dazzling displays of colourful kites made from bamboo sticks and tissue paper. Some kites were even designed to produce musical sounds as they soar. The activity is accompanied by picnics, music, and festivities, fostering a sense of hope, renewal, and unity. Witnessing and participating in this tradition for the first time was a heart-warming experience.

Navigating Security: The Police and Godfather

“Mr. Chandi are you experienced in handling firearms?” the hotel’s Security Manager asked me one day. Surprised, I replied, “I have very little experience, gained long ago during cadet training in army camps in Ceylon. Why do you ask?” He explained that as General Manager, I was expected to keep a pistol for personal protection, but first, I would need to undergo police training and obtain a Guyanese firearm licence. Reluctantly, I agreed, knowing it was better to comply with local expectations.

The Security Manager arranged for me to meet Commissioner of Police Laurie Lewis, who would later become a close friend and a regular guest at private functions in my apartment. Fortunately, I never had to use the pistol, which remained securely locked away throughout my tenure.

Another memorable encounter involved a tall, tough-looking Afro-Guyanese man who introduced himself as ‘Sevens.’ When he arrived at the hotel, the female front office staff seemed uneasy, and even the Security Manager spoke with him in a tone of respect. Sevens entered my office uninvited, shook my hand firmly, sat down, and declared, “I look after the Kingston Seawall Road area. I provide your hotel protection.”

Without hesitation, I asked the Security Manager to leave, locked my office door and responded to Sevens sarcastically, “Take a seat, please. I thought my friend Mayor Hamilton Green oversaw this area! I had a meeting with the Police Commissioner Lewis yesterday about security, but he didn’t mention you. Let me call him now to check if he knows you!” Sevens, taken aback, quickly backtracked. “OK, boss. No need to call the Commissioner. This is just a courtesy visit.” Our discussion ended shortly thereafter, but I treated him with respect in public as I escorted him out, which he seemed to appreciate.

Interestingly, Sevens would prove helpful on occasion. When a television set was stolen from the staff canteen, I called him. Within an hour, he returned with the thief and the TV. After ensuring the thief apologised to me, Sevens issued a stern warning to him: “If you ever steal from the Pegasus again, I’ll break your legs!” His reputation as the local ‘godfather’ ensured the hotel remained safe without us ever paying any protection money.

Engaging with the Trade Union

During my second week, I asked my secretary to arrange a meeting with the president of the union who oversaw hotel employee rights. “Shall I book a meeting room here?” she inquired. “No,” I replied, “set it at their head office downtown.” She was surprised but complied.

The Guyana Agricultural and General Workers’ Union (GAWU) is the country’s largest and the oldest trade union, founded in 1946. At the time, it had close links with the ruling People’s Progressive Party (PPP), whose leader, President Dr Cheddi Jagan, had long championed workers’ rights. In fact, Dr Jagan was Honorary President of GAWU for many years. Throughout of his political career he had embraced the ideology of the working class and was guided by Marxist – Leninist tenets.

When I arrived at the union’s office, both the president and general secretary seemed surprised. “We usually give new General Managers a few months to settle in before arranging a courtesy call,” they said. “Why did you come so early?” I smiled and explained, “Because you’re very important to the hotel and me. I’m a pro-union manager and want to share some quick changes I plan to implement to improve working conditions, staff meals, recreation, and remuneration. I want us to be aligned and make sure that you guys get some credit for our new initiatives.”

This proactive approach worked wonders. We maintained a harmonious relationship, communicated openly, and avoided any major union disputes during my tenure.

The ‘Racial Colour Coding’ Formula

At the monthly all-staff meeting, I introduced a new format where ten staff members, representing various departments, spoke for five minutes each. This replaced the traditional one-sided management address. The first meeting was a success, but during a post-meeting quick review I did, three senior managers in my team – an Irish Deputy General Manager, an Indo-Guyanese Financial Controller, and an Afro-Guyanese Executive Chef – raised a concern.

“Boss, the skin colour of the ten speakers wasn’t balanced,” they said. Initially, I was shocked by what seemed like an indirectly racist comment. Upon further clarification, I understood that it was a practical observation in the Guyanese context. Unintentionally, most speakers were Afro-Guyanese or ‘Portuguese’ (the term used locally for white individuals, irrespective of heritage), while there were no Amerindian Guyanese represented.

From then on, we implemented a ‘Racial Colour Coding Formula’ to ensure fair representation in public forums. If ten participants were invited, the breakdown was as follows:

5 Indo-Guyanese (Brown)

3 Afro-Guyanese (Black)

1 Amerindian Guyanese (Red)

1 Portuguese (White) or Mulatto (Mixed Black and White).

This approach reflected the demographic diversity of Guyana and was well-received by staff and stakeholders.

Management Restructuring

A month later, when my deputy, Irishman – Sean McGarth, resigned to venture into business, I took the opportunity to restructure the management team. We transferred a Bahamian hotelier from our sister property, the Nassau Beach Hotel in the Bahamas, to serve as the Rooms Division Manager at the Guyana Pegasus. I expanded the responsibilities of Raj Singh, our Indo-Guyanese Financial Controller, and promoted Courtney Hinds, our Afro-Guyanese Executive Chef to Food & Beverage Manager.

This marked a historic moment, as Courtney (a ranker who had joined the Pegasus at the inception as a cook) became the first Guyanese to hold that pivotal position at the Pegasus in its 25-year history. When Courtney was a bit nervous about the promotion, I assured him that he is fully capable of being a divisional head. Given my previous experience as a Food & Beverage Director of large five-star hotels, I became a useful mentor for Courney and later arranged for him to be qualified with a Diploma in Hotel Management. The decision was widely appreciated by our Guyanese clientele, who commended me for recognising and promoting local talent.

Subsequently, during a trip to Sri Lanka, I broke journey in Dubai, to interview and recruit a talented young Scottish chef from another international hotel chain to join the Pegasus team as Executive Chef, reporting directly to Courtney. Rather than appointing a new Deputy General Manager, I delegated equal authority to Brian, Raj, and Courtney, with all other departmental managers reporting to them. This redistribution of responsibilities allowed me to step back from the day-to-day operations and dedicate more time to strategic planning, visionary collaborations, and high-level public relations.

The restructured approach proved highly effective. Reflecting on its success, I believe it was largely due to my willingness to embrace the “racial colour coding” formula suggested to me. This approach, tailored to Guyana’s unique context, ensured a harmonious balance and celebrated the diverse strengths of the team.

Whenever needed we had help and input from an international team working for Forte PLC. They included an Italian Regional Vice President – Lorenzzo (my immediate boss, who hired me), a Sri Lankan Finance Director from the Forte head office in London – Wije, an English Regional Training Manager based in the Bahamas – Linda, an American Regional Purchasing Manager operated from Miami, and a team of multi-national regional sales team based in New York and Washington D. C. I occasionally met all those colleagues in their bases, during my travels.

Conclusion

My time in Guyana was a deeply enriching experience that reaffirmed the importance of understanding and respecting the ‘ABC’ of a host country. By immersing myself in local culture, engaging proactively with stakeholders, and adapting to unique challenges, I not only gained invaluable insights but also built lasting relationships.

From celebrating Phagwah and flying Easter kites to navigating complex security dynamics and fostering harmonious union relations, each experience contributed to my growth as a global hotelier. Guyana taught me that cultural adaptability, respect, and open communication are the true keys to success in any international assignment.

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.”
