Habitat

Terrestrial; nocturnal; inhabits the vicinity of streams and small rivers in lowland and hilly areas. Found foraging among rocks and vegetation right at the waters edge.

Diet

Feeds on small insects and invertebrates.

Reproduction

Oviparous. Courtship and mating behavior is strictly ritualized and starts in April–June. Hatchlings emerge at the end of August–September .

Note

Death-feigning behavior has been observed in this species: In captivity all of these, when handled, dropped on their back and remained immobile for around 35–45 seconds. During this period the animal becomes stiff, stretching out its fore and hind limbs. Just before the animal regained mobility, a rapid heartbeat was observed and then the animal was seen to roll over very quickly on its feet and attempt a quick escape.
