Abstract:
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.
Findings : Six valid species have been recorded; Channa ara (Deraniyagala, 1945), C. marulius (Hamilton,
1822) C. kelaartii (Gunther,1861), C. orientalis Bloch and Schneider 1801 C. punctata (Bloch, 1794) and C.
striata (Bloch, 1793). Current review suggests the exiting knowledge on the phylogeny and biogeography of
Channidae in Sri Lanka is far from complete, identifying specific gaps to be prioritized in future research.
Limitations : Current regional studies on the family Chanidae highlight the importance of a complete
systematic revision of Sri Lankan species with an integrative approach. Literature review shows the necessity
of a fresh analysis on the distribution data with ecological niche modeling and molecular phylogenetic
studies to understand biogeographical and evolutionary history of the family.
Originality / Value : Provides a consolidated account of the current knowledge on the taxonomy and
biogeography of the Sri Lankan members of the family Channidae.
