The small-headed frog or tiny oriental frog (Occidozyga diminutiva) is a species of frog in the Dicroglossidae family. It is endemic to the Philippines where it is found on Mindanao, Basilan, and in the Sulu Archipelago.[2]

Description

Occidozyga diminutiva is a small stocky frog, not exceeding 30 mm (1.2 in) in body length. Skin of back and head is smooth or faintly shagreened. Tympanum is completely hidden or with only anterior rim visible. Toes are incompletely webbed and nostrils are lateral (these characters can be used to distinguish it from Occidozyga laevis with completely webbed toes and superior nostrils). Males have a nuptial pad in their hands and paired subgular vocal sacs; with mean snout–vent length of 19 mm (0.75 in), they also appear to be smaller than females.[3]

Habitat

Its habitats are streams and quiet pools of water in undisturbed and disturbed lowland forests. This common frog is declining; it is threatened by habitat loss (loss of lowland rainforests and the pollution of mountain streams and rivers).[1]
