THE BULLFROG

26 September 2013

www.leopard.tvThe giant bullfrog Pyxicephalus adspersus and the African bullfrog Pyxicephalus edulis are the two largest types of bullfrog in South Africa. The latter mainly occurs in Mozambique and in open woodland in eastern and southern Africa. The giant bullfrog has a wider distribution in South Africa, also occurs in the more western parts of South Africa and has a finger-like distribution to the coast of the Eastern Cape province. The generic name Pixicephalus is derived from the Greek word pyxi for box and kephale for head and refers to the box-shaped head. The specific epithet adspersus is the Latin word for scattered and refers to the scattered markings on the elevated skin ridges, while the epithet edulis is the Latin word for edible.

The giant bullfrog can become 245 mm long and weigh up to 1.4 kg. It usually is dark, olive-green in colour but may vary to grey and brown, or rarely bluish. The scattered, short dorsal skin ridges are white to cream in colour. The giant bullfrog usually only waddles around and is not a prodigious jumper. It inhabits seasonal, shallow grassy plains, wetlands and other rain-filled depressions on open flat terrain in grasslands, thickets and bushveld. For much of the year it hibernates in mud up to 1 m underground and only emerges after sufficient rain during the wet season...(Become a subscriber for more)
