Arnoldichthys spilopterus, the Niger tetra, is a characin endemic to Nigeria. It is the only member of its genus.
Arnoldichthys spilopterus is a tropical freshwater species found only in a limited number of locations in Nigeria (Ogun and Niger rivers). [1] Males are on average 9.6 centimetres (3.8 in) long. Its diet consists of worms, insects, and crustaceans. Females in captivity can lay about 1,000 eggs, which hatch within 30–34 hours. [2]
This species is currently classified as endangered by the IUCN due to its limited range coupled with losses to the aquarium trade and ongoing habitat degradation. [1]
Niger is a landlocked nation in West Africa located along the border between the Sahara and Sub-Saharan regions. Its geographic coordinates are longitude 16°N and latitude 8°E. Its area is 1.267 million square kilometers, of which 1 266 700 km2 is land and 300 km2 water, making Niger slightly less than twice the size of France.
Tetra is the common name of many small freshwater characiform fishes. Tetras come from Africa, Central America, and South America, belonging to the biological family Characidae and to its former subfamilies Alestidae and Lebiasinidae. The Characidae are distinguished from other fish by the presence of a small adipose fin between the dorsal and caudal fins. Many of these, such as the neon tetra, are brightly colored and easy to keep in captivity. Consequently, they are extremely popular for home aquaria.
The white-throated guenon, also known as the red-bellied monkey and the red-bellied guenon, is a diurnal primate that lives on trees of rainforests or tropical areas of Nigeria and Benin.
Sclater's guenon, also known as Sclater's monkey and the Nigerian monkey, is an Old World monkey that was first described by Reginald Innes Pocock in 1904 and named after Philip Sclater. It is an arboreal and diurnal primate that lives in the forests of southern Nigeria. It should not be confused with the closely related species, the white-throated guenon, which occurs in Nigeria and Benin. Sclater's guenon was formerly classified as a subspecies of the red-eared guenon.
The black duiker, also known as tuba in Dyula, is a forest-dwelling duiker found in the southern parts of Sierra Leone, Liberia, Côte d'Ivoire, Ghana, Benin, and Nigeria.
The mona monkey is an Old World monkey that lives in western Africa between Ghana and Cameroon. The mona monkey can also be found on the island of Grenada as it was transported to the island aboard slave ships headed to the New World during the 18th century. This guenon lives in groups of up to thirty-five in forests. It mainly feeds on fruit, but sometimes eats insects and leaves. The mona monkey has brown agouti fur with a white rump. Its tail and legs are black and the face is blue-grey with a dark stripe across the face. The mona monkey carries food in cheek pouches.
The crested servaline genet, also known as the crested genet, is a genet species endemic to Nigeria and Cameroon. As the population has declined due to loss of habitat, it is listed as Vulnerable on the IUCN Red List. It was first recorded in the Mamfe Division in Cameroon and initially considered a subspecies of the servaline genet. But now it is regarded as a distinct species.
Environmental issues in the Niger Delta are caused by its petroleum industry. The delta covers 20,000 km2 (7,700 sq mi) within wetlands of 70,000 km2 (27,000 sq mi) formed primarily by sediment deposition. Home to 20 million people and 40 different ethnic groups, this floodplain makes up 7.5% of Nigeria's total land mass. It is the largest wetland and maintains the third-largest drainage basin in Africa. The Delta's environment can be broken down into four ecological zones: coastal barrier islands, mangrove swamp forests, freshwater swamps, and lowland rainforests. Fishing and farming are the main sources of livelihoods for majority of her residents.
The northwestern fat mouse is a species of rodent in the family Nesomyidae. It is native to tropical West Africa where it occurs on grassland and crop land.
The dainty fat mouse is a species of rodent in the family Nesomyidae. It is found in Benin, Burkina Faso, Mali, Niger, Nigeria, and Senegal. Its natural habitat is subtropical or tropical dry shrubland.
The spot-winged starling is a species of starling in the family Sturnidae. It breeds in northern India and western Nepal; it winters in Northeast India, north-eastern Bangladesh and Myanmar. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. This species was first bred in the UK by Mrs K.M. Scamell in 1969. A detailed account of the breeding can be found in the January/February 1970 edition of Foreign Birds, the journal of the Foreign Bird League.
Savile's bustard is a species of bird in the family Otididae. Otididae are an Old-World and understudied family of birds mostly found in Afro-Tropical regions. It is found in Burkina Faso, Cameroon, Chad, Ivory Coast, Gambia, Mali, Mauritania, Niger, Nigeria, Senegal, and Sudan.
Pennant's colobus or Pennant's red colobus is a species of tree-dwelling primate in the family Cercopithecidae. It is endemic to tropical Central Africa. Three subspecies have traditionally been recognised but its distribution is peculiarly disjunct and has been considered a biogeographical puzzle, with one population on the island of Bioko, a second in the Niger River Delta in southern Nigeria, and a third in east-central Republic of Congo. It is found in rainforests and marshy forests. It is threatened by habitat loss and hunting for bushmeat.
The Voi shrew is a species of mammal in the family Soricidae. It is found in Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Ethiopia, Ghana, Kenya, Mali, Niger, Nigeria, Somalia, Sudan, and Togo. Its natural habitat is dry savanna.
The wildlife of Niger is composed of its flora and fauna. The wildlife protected areas in the country total about 8.5 million hectares, which is 6.6% of the land area of the country, a figure which is expected to eventually reach the 11% percent target fixed by the IUCN with addition of more areas under the reserve category. The dama gazelle has become a national symbol. Under the Hausa name meyna or ménas the dama appears on the badge of the Niger national football team, who are popularly called the Ménas.
The Niger stingray or smooth freshwater stingray is a species of stingray in the family Dasyatidae, native to rivers in Nigeria and Cameroon. Attaining a width of 40 cm (16 in), this species can be distinguished by its thin, almost circular pectoral fin disk, slightly projecting snout tip, and mostly smooth skin with small or absent dermal denticles. The Niger stingray feeds on aquatic insect larvae and is ovoviviparous. The long stinging spine on the tail of this ray can inflict a painful wound. It has been assessed as Critically Endangered by the International Union for Conservation of Nature (IUCN), as its numbers are declining in some areas and it faces heavy fishing pressure and habitat degradation.
Protomelas spilopterus is a species of cichlid endemic to Lake Malawi. It is believed to be a specialist predator on fish fry. This species can reach a length of 24 centimetres (9.4 in) TL. It can also be found in the aquarium trade.
The West African giraffe, also known as the Niger giraffe or Nigerian giraffe is a species or subspecies of the giraffe distinguished by its light colored spots. It is found in the Sahel of West Africa.
The Niger Delta red colobus is a critically endangered species of colobus monkey endemic to the western part of the Niger Delta. It is threatened by hunting and habitat loss.
Dagetichthys lakdoensis is a species of freshwater sole native to the Bénoué basin in Cameroon, with recent records from Nigeria in the Niger Delta. This species grows to a length of 40 centimetres (16 in) TL. This species is one of only two known members of its genus, the other being the marine Dagetichthys lusitanica.
