Habitat and Ecology:This species occurs in broad-leaved evergreen forest, secondary forest, grassland and swamps. It inhabits vegetated areas with constantly humid substrates, and breeds in shaded still waters such as ponds and temporary pools in forests. On Tokunoshima the species occurs in and near sugar cane fields, at altitudes of 100-200m asl (Utsonomiya, Utsonomiya and Kawachi 1978). It is terrestrial, and while eggs are laid on land in one or several clutches, the larvae develop in water.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Recent deforestation and other forms of land development, as well as road and drainage ditch construction, have been causing population declines on each island. It is also collected illegally for the pet trade.
