Quasipaa spinosa

Quasipaa spinosa, the giant spiny frog, can grow above 10cm, making it the largest frog in Hong Kong, and males may weigh at least 133g. It is dark brown with dense yellowish mottling. Its altitude range is about 200–1,500m, and no certain records exist from Vietnam, where earlier records may refer to another species (Wikipedia, general species account).

It breeds in streams, laying eggs in water under stones. Males call near slow-flowing stretches of streams or pools adjacent to streams, with an advertisement call of three to seven notes, the last being the longest. Farming it may not reduce pressure on wild populations (Wikipedia, general species account).
