Snakes of Sri Lanka


According to the published literature on snake fauna of Sri Lanka, a total of 103 snake species occur in the island, of which 49 are endemic. Out of above 103 species 88 snakes inhabit inland (terrestrial, fossorial, arboreal or freshwater) eco systems while 15 sea snakes are also to date recorded from the Indian Ocean around the island. However status of following species is doubtful and needs to be examined with more samples.
1) Argyrogena fasciolata         2) Dendrelaphis oliveri        3) Dryocalamus gracilis        4) Typhlops ceylonicus
5) Typhlops lankaensis           6) Typhlops malcolmi           7) Typhlos tenebrarum         8) Typhlops veddae
9) Typhlops violaceus            10) Platyplectrurus madurensis                                            11) Rhinophis dorsimaculatus
12) Rhinophis porrectus         13) Uropeltis ruhunae           14) Enhydris enhydris
