Stout sand snake (Maharashtra)

Distribution

In Maharashtra it is reported from Bombay presidency north of 19 degree (Thana and Damanganga districts, Bulsar, Panch Mahal), C.P(Nagpur) and Amravati. In Gujarat; Surat, Valsad, Navsari. In Madhya Pradesh it is recorded from Ujjain and Hoshangabad. These records show that this species is distributed in a very narrow range, including three western Indian states, namely Gujarat (central and south), Maharashtra (northern) and Madhya Pradesh (mainly southern west).

Food and behaviour

Its habits are both terrestrial and arboreal.[1]

In captivity (for a short period), it was observed that the snakes were timid and well set without any aggression. Five types of lizards (Hemidactylus flaviviridis, H. triedrus, Calotes versicolor, and Eutropis carinata and four types of frogs (Duttaphrynus melanostictus, Euphlyctis cyanophlyctis, Sphaerotheca breviceps, and Polypedates maculatus) were provided and accepted as food.

Reproduction

A female collected in Gujarat laid eight capsule shaped eggs.
