Diversity of Serpentoid Reptiles (Snakes)


According to the published literature on snake fauna of Sri Lanka, a total of 101 snake species occur in the island, of which 47 are endemic. Out of above 101 species 86 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
