HabitatRead full entry
The terrestrial habitat is largely moist forest, or sites where mountain forests previously existed, such as rice fields, tea gardens, meadows covering the shores of mountain ponds and lakes, forest edges, etc.. The animals generally remain close to water (AmphibiaWeb, 2010). Aquatic habitats include various freshwaters including permanent pools and forest streams, natural and artificial ponds, rain puddles and swamps (Seglie, 2002). Breeding occurs in the shallow areas of these water bodies. In the southern part of its range it is generally an upland species occurring at elevations between 1,000 - 3,000 m., in the northern part of its range T. verrucosus is reported from low hills below 1,000 m. (IUCN, 2010)
Although it is not usually common, population density may locally be very high, from 71 to 101 per 100 square meters breeding pond (Seglie, 2002). Food consists of aquatic and terrestrial insects, bivalves, cannibalized eggs of T. verrucosus and vegetal material (Anders et al., 1998). Young larvae feed on mosquito larvae, microcrustaceans, chironomids and various other benthic prey; larvae of later stages prey on aquatic insects and small crabs; after metamorphosis food consists of small bivalves and terrestrial food such as Collembola, larval Lepidoptera, larval Diptera and isopods. The adult diet consists of Lumbricidae, larval Diptera, Coleoptera, Lepidoptera, and Odonata, adult dytiscid beetles, larvae of frogs and cannibalized eggs (Dasgupta, 1996).
