Goliath Frog (Conraua goliath), FMNH no. 248830. Field Museum of Natural History, Chicago. Conservation status: endangered. The largest frog in the world is known only from the Nkongsamba region of southwestern Cameroon and south to Monte Alen in mainland Equatorial Guinea. Populations have declined by 50% in the last 15 years. The main threat to this species is hunting for food and it is considered a delicacy. New, sophisticated traps are being used in Cameroon. Goliath frogs are imported from Cameroon to the USA by animal dealers for zoos, the pet trade and competitive frog races. It is also affected by the loss of forest for agriculture, logging, and human settlements, as well as by sedimentation of its breeding streams in its tropical forest habitat. No conservation programs exist and the species is under particular threat due to its limited range.  ..As biologists describe new species and add to our understanding of the interrelated nature of life on Earth, a species becomes extinct every 20 minutes (100 to 1000 times the background extinction rate as seen in the fossil record). Collections in natural history museums play important roles in conservation, education and research. Most of that work and the associated specimens are not on public display in museums? typically, less than five percent of specimens are exhibited.
