Ichthyophis billitonensis

Ichthyophis billitonensis, the Billiton Island caecilian, is a species of amphibian in the family Ichthyophiidae endemic to the Belitung island, Indonesia. It was rediscovered in 2022 from Gunung Tajam, Belitung, after not having been recorded since the original description of the species in 1965. This appears to be a small species, measuring 135 mm in total length. Habitat requirements are unknown but it probably inhabits moist lowland forests. It may be threatened by habitat loss caused by opencast tin mining.
