A team of ichthyologists in their latest study on carnivorous fish of Sri Lanka points out that Channa orientalis also known as the Ceylon snakehead, is the only pelvic-fin less snakehead in Sri Lanka.
Snakeheads are one of the main carnivorous groups of freshwater fish in Sri Lanka. They belong to the family Channidae and the genus Channa. There are six species of Channa in Sri Lanka, two of which are endemic. The two endemic species are Channa ara and Channa orientalis. Channa orientalis also known as the Ceylon snakehead is the only pelvic-fin less snakehead in Sri Lanka.
The latest study on the genetic diversity and morphological stasis in the Ceylon Snakehead found that the taxonomic identity and the type locality of this species were not certain.
Scientist Hiranya Sudasinghe told The Island yesterday: “We show that C. orientalis is composed of two geographically and genetically distinct lineages but which show remarkable morphological similarity between the two lineages. The recognition of two distinct genetic lineages is important because, when it comes to conservation management of this species, these two lineages could be recognised as two Evolutionary Significant Units that would deserve separate conservation attention.”
“We argue that the type locality of C. orientalis is south-western Sri Lanka, to which the species is endemic. Channa orientalis is distinguished from other species of Channa by the absence of pelvic fins, adult colouration in life, dorsal- and anal-fin ray counts, number of vertebrae, and scale counts,” the team pointed out.
This species feeds like a ciclids, experts point out.
The team of scientists comprises of Hiranya Sudasinghe of Evolutionary Ecology and Systematics Lab, Department of Molecular Biology and Biotechnology, University of Peradeniya, Peradeniya, Sri Lanka/ Postgraduate Institute of Science, University of Peradeniya, Peradeniya, SriLanka, R.H.Tharindu Ranasinghe of Butterfly Conservation Society of Sri Lanka, Rohan Pethiyagoda of Ichthyology Section, Australian Museum, 1 William Street, Sydney, NSW 2010, Australia, Madhava Meegaskumbura of Guangxi Key Laboratory of Forest Ecology & Conservation, College of Forestry, Guangxi University, Nanning, People’s Republic of China and Ralf Britz Senckenberg Naturhistorische Sammlungen Dresden, Museum für Tierkunde, Königsbrücker Landstrasse 159, 01109 Dresden, Germany
As the type species of the genus Channa, the identity of the pelvic-finless snakehead Channa orientalis Bloch is important to channid systematics. Although this name has been attached to a Sri Lankan species for the past 160 years, its vaguely specified type locality, ‘India Orientali’, has long cast doubt as to its origin.
Based on a collection across its range in the island and analysis of the cytochrome c oxidase subunit 1 (cox1) barcoding gene, scientists show that the Sri Lankan pelvic-finless Channa is composed of two geographically discrete lineages separated by an uncorrected pairwise cox1 genetic distance of 6.9–8.1%.
The minimum genetic distance between these two lineages and other species of the Gachua group of Channa is 5.1%. Despite their genetic divergence, the two lineages exhibit remarkable morphological stasis: they are indistinguishable from each other in external morphology.

Navy seizes an Indian fishing trawler poaching in Sri Lankan waters north of Talaimannar
During an operation conducted in the wee hours of Tuesday (23 Dec 25), the Sri Lanka Navy seized an Indian fishing trawler and apprehended 12 Indian fishermen, while they were poaching in Sri Lankan waters north of Talaimannar.
Recognizing the detrimental effects of poaching on marine resources and the livelihoods of local fishing communities, the Sri Lanka Navy continues to conduct regular operations as
proactive measures to deter such activities. These efforts underscore the collective robust approach steadfast commitment to safeguarding the nation’s marine ecosystems while ensuring the economic security and wellbeing of its citizens.
The fishing trawler along with the fishermen held in this operation was handed over to the Fisheries Inspector of Mannar for onward legal proceedings.

Sri Lanka’s coastline faces unfolding catastrophe: Expert
Sri Lanka is standing on the edge of a coastal catastrophe, with the nation’s lifeline rapidly eroding under the combined assault of climate change, reckless development and weak compliance, Director General of the Department of Coast Conservation and Coastal Resource Management (DCC&CRM) Dr. Terney Pradeep Kumara has warned.
“This is no longer an environmental warning we can afford to ignore. The crisis is already unfolding before our eyes,” Dr. Kumara told The Island, cautioning that the degradation of Sri Lanka’s 1,620-kilometre coastline has reached a point where delayed action could trigger irreversible damage to ecosystems, livelihoods and national security.
He said accelerating coastal erosion, rising sea levels, saltwater intrusion and the collapse of natural barriers, such as coral reefs and mangroves, are placing entire coastal communities at risk. “When mangroves disappear and reefs are destroyed, villages lose their first line of defence. What follows are floods, loss of homes, declining fisheries and forced displacement,” he said.
Dr. Kumara stressed that the coastline is not merely a development frontier but the backbone of Sri Lanka’s economy and cultural identity. “More than half of our tourism assets, fisheries and key infrastructure are concentrated along the coast.
If the coast fails, the economy will feel the shock immediately,” he warned.
Condemning unregulated construction, illegal sand mining and environmentally blind infrastructure projects, he said short-term economic interests are pushing the coastline towards collapse. “We cannot keep fixing one eroding beach while creating three new erosion sites elsewhere. That is not management—it is destruction,” he said, calling for science-driven, ecosystem-based solutions instead of politically convenient quick fixes.
The Director General said the Department is intensifying enforcement and shifting towards integrated coastal zone management, but warned that laws alone will not save the coast. “This is a shared responsibility. Policymakers, developers, local authorities and the public must understand that every illegal structure, every destroyed mangrove, weakens the island’s natural shield,” he added.
With climate change intensifying storms and sea surges, Dr. Kumara warned that Sri Lanka’s vulnerability will only worsen without urgent, coordinated national action. “The sea has shaped this nation’s history and protected it for centuries. If we fail to protect the coast today, we will be remembered as the generation that allowed the island itself to be slowly eaten away,” he went on to say.
