This species can reach a length of 9.3 centimetres (3.7 in) TL.
WThe Lake Oku clawed frog is a species of frog in the family Pipidae, endemic to Lake Oku, a small crater lake in northwest Cameroon. It is a small, dark-coloured, fully aquatic frog with a length of 28 to 36 mm, males being slightly smaller than females. The International Union for Conservation of Nature has rated this frog as "critically endangered" on the basis of its small area of occurrence at a single location, and the possibility that introduction of non-native fish into the lake could cause the frog to be wiped out.

WThe myaka (Myaka myaka) is a critically endangered species of cichlid endemic to Lake Barombi Mbo in western Cameroon. It prefers open, deeper waters where it feeds on phytoplankton and small insects, only venturing into shallower waters to spawn. This species can reach a length of 6.7 centimetres (2.6 in) SL. It is currently the only known species in its genus, but it is very close to Sarotherodon. The myika is threatened because of pollution and sedimentation due to human activities. It is potentially also threatened by large emissions of carbon dioxide (CO2) from the lake's bottom (compare Lake Nyos), although studies indicate that Barombo Mbo lacks excess amounts of this gas. Konia, Pungu and Stomatepia are three other equally threatened genera of ciclids that also are endemic to Lake Barombi Mbo.
WThe nsess (Stomatepia mariae) is a species of cichlid endemic to Lake Barombi Mbo in western Cameroon. It can also be found in the aquarium trade. It is critically endangered because of pollution and sedimentation due to human activities. It is potentially also threatened by large emissions of carbon dioxide (CO2) from the lake's bottom (compare Lake Nyos), although studies indicate that Barombo Mbo lacks excess amounts of this gas.

WPetropedetes johnstoni is a species of frog in the family Petropedetidae. It is endemic to coastal Cameroon and known with certainty only from few localities. For a period, Petropedetes newtonii was considered a junior synonym of this species, leading to a much broader distribution. The two species are now considered distinct, but information on Petropedetes johnstoni sensu stricto is limited. Common name Johnston's water frog has been coined for this species.
WPhrynobatrachus njiomock is a species of frogs in the family Phrynobatrachidae. It is endemic to Cameroon and is only known from Mount Oku where it occurs near Lake Oku. It has not been observed after 2010 and might already be extinct. The specific name njiomock means "eleventh" in Oku language and refers to the name "Phrynobatrachus sp. 11" that Jean-Louis Amiet used in 1978 to refer to a specimen collected near Lake Oku. Common name Lake Oku puddle frog has been proposed for this species.
WThe pindu is a critically endangered species of cichlid endemic to Lake Barombi Mbo in western Cameroon.
WThe pungu is a species of cichlid endemic to Lake Barombi Mbo in Cameroon where it prefers shallow waters of about 1 to 3 metres in depth. It feeds on invertebrates, sponges, diatoms and macrophytes. This species can reach a length of 10 centimetres (3.9 in) SL. It is currently the only known member of its genus, but it is very close to Sarotherodon. The pungu is threatened because of pollution and sedimentation from human activities. Konia, Myaka and Stomatepia are three other equally threatened genera of cichlids that also are endemic to Lake Barombi Mbo. The specific name of this fish honours the Fisheries Development Officer of Nigeria, P.I.R. MacLaren, who used his position to collect specimens of fishes, including the type of this species.

This species reaches a length of 18.5 centimetres (7.3 in) SL. It is critically endangered because of pollution and sedimentation due to human activities. It is potentially also threatened by large emissions of carbon dioxide (CO2) from the lake's bottom (compare Lake Nyos), although studies indicate that Barombo Mbo lacks excess amounts of this gas.
WEisentraut's shrew is a species of mammal in the family Soricidae. It is endemic to Cameroon. Its natural habitat is subtropical or tropical high-altitude grassland.
WStomatepia is a genus of cichlids endemic to Lake Barombi Mbo in western Cameroon. Although generally recognized as distinct, the genus is very close to Sarotherodon. The Stomatepia species are all recognized as critically endangered by the IUCN because of pollution and sedimentation due to human activities. They are potentially also threatened by large emissions of carbon dioxide (CO2) from the lake's bottom (compare Lake Nyos), although studies indicate that Barombo Mbo lacks excess amounts of this gas. Konia, Myaka and Pungu are three other equally threatened genera of ciclids that also are endemic to Lake Barombi Mbo.
WThe volcano clawed frog is a species of frog in the family Pipidae endemic to Cameroon. Its natural habitats are subtropical or tropical high-altitude grassland, swamps, intermittent freshwater lakes, freshwater marshes, pastureland, and aquaculture ponds. It is threatened by habitat loss.
