Western Chimpanzee
The western chimpanzee, or West African chimpanzee, (''Pan troglodytes verus'') is a Critically Endangered subspecies of the common chimpanzee. It inhabits western Africa, specifically Côte d'Ivoire, Guinea, Liberia, Mali, Senegal, Ghana, Guinea-Bissau, but has been extirpated in three countries: Benin, Burkina Faso, and Togo. Etymology The taxonomical genus ''Pan'' is derived from the Greek god of fields, groves, and wooded glens, Pan. The species name ''troglodytes'' is Greek for 'cave-dweller', and was coined by Johann Friedrich Blumenbach in his ''Handbuch der Naturgeschichte'' (''Handbook of Natural History'') published in 1779. ''Verus'' is Latin for 'true', and was given to this subspecies in 1934 by Ernst Schwarz, who originally named it as ''Pan satyrus verus''. Taxonomy and genetics The western chimpanzee (''P. t. verus'') is a subspecies of the common chimpanzee (''Pan troglodytes''), along with the central chimpanzee (''P. t. troglodytes''), the Nigeria-Ca ...

Pygmy Hippopotamus
The pygmy hippopotamus or pygmy hippo (''Choeropsis liberiensis'') is a small hippopotamid which is native to the forests and swamps of West Africa, primarily in Liberia, with small populations in Sierra Leone, Guinea, and Ivory Coast. It has been extirpated from Nigeria. The pygmy hippo is reclusive and nocturnal. It is one of only two extant species in the family Hippopotamidae, the other being its much larger relative, the common hippopotamus (''Hippopotamus amphibius'') or Nile hippopotamus. The pygmy hippopotamus displays many terrestrial adaptations, but like the hippo, it is semiaquatic and relies on water to keep its skin moist and its body temperature cool. Behaviors such as mating and giving birth may occur in water or on land. The pygmy hippo is herbivorous, feeding on ferns, broad-leaved plants, grasses, and fruits it finds in the forests. A rare nocturnal forest creature, the pygmy hippopotamus is a difficult animal to study in the wild. Pygmy hippos were unkn ...

West African Lion
''Panthera leo leo'' is a lion subspecies, which is present in West Africa, northern Central Africa and India. In West and Central Africa it is restricted to fragmented and isolated populations with a declining trajectory. It has been referred to as the Northern lion. Results of a phylogeographic study indicate that lion populations in West and Central African range countries are genetically close to populations in India, forming a major clade distinct from lion populations in Southern and East Africa. In 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group subsumed lion populations according to the major clades into two subspecies, namely ''P. l. leo'' and ''P. l. melanochaita''. Within ''P. l. leo'' three subclades are clearly distinguishable. One from Asia, which includes the extinct Barbary lions of North Africa, another one from West Africa and a third one from Central Africa, north of the rainforest belt. ''P. l. leo'' is regionally extinct in North A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nimba Otter Shrew
The Nimba otter shrew (''Micropotamogale lamottei'') is a dwarf otter shrew and belongs to the mammal family Potamogalidae. Otter shrews are shrew-like afrotherian mammals found in sub-Saharan Africa. They are most closely related to the tenrecs of Madagascar. This species belongs to the genus '' Micropotamogale'', literally meaning "tiny river weasel". It is native to the Mount Nimba area which rests along the border of Liberia, Guinea, and Côte d’Ivoire (Ivory Coast) in West Africa. Description The Nimba otter shrew is a small-bodied mammal. Weighing only about it has a body length of with a quarter to a third of its body size being its tail. It has been described as a "miniature sea otter with a rat tail". Its pelage is long, hiding its ears and eyes, and almost always universally colored (usually brown, but black and gray otter shrews have been spotted). Evolution and life history The Nimba otter shrew is classified as a member of Potamogalidae, which is related ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myotis Nimbaensis

Lamotte's Roundleaf Bat
Lamotte's roundleaf bat (''Hipposideros lamottei'') is a species of bat found only at Mount Nimba on the border of Côte d'Ivoire, Guinea and Liberia. It is critically endangered. Taxonomy It was described as a new species in 1984 by French zoologist André Brosset. He chose the species name ''lamottei'' after Dr. Maxime Lamotte, who was also a French zoologist. Its status as a species has been called into question, and some suggested that it might be synonymous with Noack's roundleaf bat, ''Hipposideros ruber''. While its mitochondrial gene for cytochrome b may only differ from that of ''H. ruber'' by only 6%, a 2013 study found that it was morphologically distinct from it. Based on its morphology, it is in the ''caffer/ruber'' species complex of its genus. Other species in this complex include: * Sundevall's roundleaf bat, ''H. caffer'' * Noack's roundleaf bat, ''H. ruber'' *'' H. tephrus'' Based on genetic analysis, it has been hypothesized that Lamotte's roundleaf bat ...

Western Nimba Toad
''Nimbaphrynoides'' is a monotypic genus of true toads from highlands in the Mount Nimba region of the West African countries of Guinea, Liberia, and Côte d'Ivoire. The sole species is ''Nimbaphrynoides occidentalis''. Along with ''Nectophrynoides'', ''Eleutherodactylus jasperi'', and '' Limnonectes larvaepartus'', ''Nimbaphrynoides'' is one of the only anurans that combine internal fertilization with ovoviparity.Wells (2007). ''The Ecology and Behavior of Amphibians.'' Pp. 486–487. Taxonomy and systematics ''Nimbaphrynoides occidentalis'' was first described as ''Nectophrynoides occidentalis'' by Fernand Angel in 1943. A second species from Mount Nimba, ''Nectophrynoides liberiensis'', was described in 1979. The two were then transferred to a newly erected genus ''Nimbaphrynoides'' in 1987. The two species were similar except for the larger size of ''N. liberiensis'' compared to ''N. occidentalis'' and some small colour differences. However, their calls are similar, a ...
