Rare and Endangered Animals
According to one estimate, 285 species of Vertebrate are reported to be endemic to Western Ghats, which include 12 mammals, 16 birds, 89 reptiles, 87 amphibians, and 84 fresh water fishes. Among large mammals, no species is endemic to Kerala. However, birds such as White breasted laughing thrush, Wayanad laughing thrush, White bellied shortwing, Southern treepie, Rufous babbler are possible endemic birds which may slightly overlap state boundaries in the southern Western Ghats.
High diversity area like West Malaysia has only about 10 endemic snakes, whereas the South West India has about 55. Among reptiles, Cochin forest cane turtle and Travancore tortoise are endemic to evergreen forests of southern Western Ghats. Arboreal agamid genera Otocryptis and Salea and the rare endemic genus of burrowing snake, Xylophus and others of the family Uropeltidae have been accorded high conservation value.
The
monotypic agamid genus Dravidogecko is reported from Anamalais only.
Thirty species of lizards are reported endemic to Western Ghats which
include Calotes rouxi, Cnemaspis sisparensis,
C.wynadensis and Chalcides pentadactylus. Out of 57
endemic snakes in the Western Ghats four species viz., Boiga
dightsni, Melanophidum bilineatum, Plectrurus aurenus
