Purpose : Fish species of the family Channidae, commonly known as snakeheads, represent biggest and most caught native freshwater species in Sri Lanka. Despite importance for biodiversity and fisheries in Sri Lanka, members of this family are one of the least studied on taxonomic status and geographic distribution. Research Method : As an initial step of a study to revise the taxonomy and biogeography of freshwater fish in the family Channidae based on molecular phylogenetic and morphological relationships and biogeographical affinities, authors reviewed all the available published information and examined the specimens available at the National Museum of Sri Lanka.
