Range edit

Occidozyga baluensis is found in northwestern Borneo (Sarawak, Malaysia, Brunei, and Kalimantan, Indonesia) and was also recorded once in Lampung, Sumatra, although the latter is questionable.[1] Its name refers to its type locality, "Mount Kina Balu, North Borneo".[2]

Description edit

Occidozyga baluensis are small–medium-sized frogs. Males grow to a snout–vent length of about 25 mm (0.98 in) and females to 35 mm (1.4 in). Dorsal colouration is variable, brown, grey, or olive, sometimes with dark markings. Some individuals have a vertebral stripe. The belly is cream with an abundance of brown spots. Tadpoles have a long tail with low tail fin; the tip is pointed. The mouth is terminal in position and the orifice appears quite small.[3]

Habitat edit

Occidozyga baluensis inhabit shallow ponds or water-filled depressions where clear water seeps out at the base of a slope. Tadpoles live in the shallow water film that covers the leaf litter in seepage areas. They are predatory and ingest small invertebrates.[3] The species is threatened by habitat loss caused by clear-cutting.[1]
