This species occurs on the eastern peninsula and southeastern peninsula of Sulawesi, and on Muna, Buton, Wowoni and Kabaena Islands, in Indonesia, where it occurs up to 600m asl. It also occurs in the Maluku Islands (Halmahera, Seram, Ambon, Haluku, Saparua, Buru, and some other smaller islands) and is widespread on the New Guinea mainland in Indonesia and Papua New Guinea. It ranges up to 1,600m asl in New Guinea.
Habitat and Ecology
It is a semi-aquatic species living and breeding along side and in small and large streams, swamps and pools in tropical rainforest. It is also found in rural gardens, large pools, and degraded forest.
It is an abundant species, although it is only considered reasonably common in New Guinea.
The main threat is exploitation for human food, since the animals on Sulawesi, which represent an undescribed species, are very large. It is also eaten in New Guinea.
It occurs in the Raua Aopa Nature Reserve and several protected areas in New Guinea. The taxonomy of this species requires clarification to determine whether or not it harbours one or more sibling species with potentially restricted ranges.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This form is a complex that probably includes more than one species. The population on Sulawesi appears to be an undescribed species (D. Iskandar pers. comm.).
