Country distribution from AmphibiaWeb's database: Seychelles

View distribution map using BerkeleyMapper.
This is a relatively abundant species, inhabiting all of the granitic islands in the Seychelles group. This species can be found in moist leaf litter and soil, under wood and rocks, in debris piles, and occasionally in streams.

Life History, Abundance, Activity, and Special Behaviors
Not much is known about the behavior and diet. They presumably eat earthworms and terrestrial arthropods. There have been reports of this species consuming frogs. In captivity, they are sit-and-wait predators with a strong bite

Trends and Threats
They seems to be abundant where found.

Relation to Humans
Its diet of arthropods helps to control pest populations and its burrowing aids in soil turning and aeration.
