Walter's duiker (Philantomba walteri) is a species of duiker found in Togo, Benin and Nigeria. It was described in 2010.  Its name commemorates Professor Walter Verheyen, who was the first to obtain a specimen of this species of duiker from Togo in 1968. 
It measures under 40 cm (16 in) tall at the shoulder, and weighs between 4 and 6 kg (8.8 and 13.2 lb). It was described in 2010 following comparison of specimens in museum collections with those from bushmeat markets.  It is a small antelope and is characterised by a slightly raised back, short legs, a small head and short, rounded ears. It has a long tail, pedal glands and a distinctive stripe above the eye.  It is intermediate in size between the larger Maxwell's duiker (Philantomba maxwellii) and the smaller blue duiker (Philantomba monticola), but is clearly different in morphology, cranial structure and DNA analysis. 
Walter's duiker was first recognised as a new species in 2010 when specimens of this duiker were found on sale at a bushmeat market. The duikers have not been observed by researchers in the wild, (until Spring of 2021, via video cameras) but are believed to come from the Dahomey Gap, an area of savannah which is a portion of the Guinean forest-savanna mosaic with a relatively dry climate, that extends all the way to the coast in Benin, Togo and Ghana, separating the rainforest zones on either side. 
This species is known from only forty-one specimens found in the last few decades and it has not been viewed in the wild. The International Union for Conservation of Nature considers the species too poorly known for it to be able to evaluate this animal's conservation status, so they have assessed it as being of "data deficient". 
A duiker is a small to medium-sized brown antelope native to sub-Saharan Africa, found in heavily wooded areas. The 22 extant species, including three sometimes considered to be subspecies of the other species, form the subfamily Cephalophinae or the tribe Cephalophini.
Bushmeat is meat from wildlife species that are hunted for human consumption, most often referring to the meat of game in Africa. Bushmeat represents a primary source of animal protein and a cash-earning commodity for inhabitants of humid tropical forest regions in Africa, Latin America and Asia. Bushmeat is an important food resource for poor people, particularly in rural areas.
The African palm civet, also known as the two-spotted palm civet, is a small feliform mammal widely distributed in sub-Saharan Africa. It is listed as Least Concern on the IUCN Red List.
The gerenuk, also known as the giraffe gazelle, is a long-necked antelope found in parts of East Africa. The sole member of the genus Litocranius, the gerenuk was first described by the naturalist Victor Brooke in 1879. It is characterised by its long, slender neck and limbs. The antelope is 80–105 centimetres tall, and weighs between 18 and 52 kilograms. Two types of colouration are clearly visible on the smooth coat: the reddish brown back or the "saddle", and the lighter flanks, fawn to buff. The horns, present only on males, are lyre-shaped. Curving backward then slightly forward, these measure 25–44 cm.
The royal antelope is a West African antelope, recognized as the world's smallest antelope. It was first described by Swedish zoologist Carl Linnaeus in 1758. It stands up to merely 25 centimetres (10 in) at the shoulder and weighs 2.5–3 kilograms (5.5–6.6 lb). A characteristic feature is the long and slender legs, with the hindlegs twice as long as the forelegs. Horns are possessed only by males; the short, smooth, spiky horns measure 2.5–3 centimetres (1.0–1.2 in) and bend backward. The soft coat is reddish to golden brown, in sharp contrast with the white ventral parts. In comparison to Bates's pygmy antelope, the royal antelope has a longer muzzle, broader lips, a smaller mouth and smaller cheek muscles.
The bay duiker, also known as the black-striped duiker and the black-backed duiker, is a forest-dwelling duiker native to western and southern Africa. It was first described by British zoologist John Edward Gray in 1846. Two subspecies are identified. The bay duiker is reddish-brown and has a moderate size. Both sexes reach 44–49 cm (17–19 in) at the shoulder. The sexes do not vary considerably in their weights, either; the typical weight range for this duiker is 18–23 kg (40–51 lb). Both sexes have a pair of spiky horns, measuring 5–8 cm (2.0–3.1 in). A notable feature of this duiker is the well-pronounced solid stripe of black extending from the back of the head to the tail.
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 blue duiker is a small antelope found in central, southern and eastern Africa. It is the smallest duiker. The species was first described by Swedish naturalist Carl Peter Thunberg in 1789. 12 subspecies are identified. The blue duiker reaches 32–41 centimetres (13–16 in) at the shoulder and weighs 3.5–9 kilograms (7.7–19.8 lb). Sexually dimorphic, the females are slightly larger than the males. The dark tail measures slightly above 10 centimetres (3.9 in). It has short, spiky horns, around 5 centimetres (2.0 in) long and hidden in hair tufts. The subspecies show a great degree of variation in their colouration. The blue duiker bears a significant resemblance to Maxwell's duiker.
Jentink's duiker, also known as gidi-gidi in Krio and kaikulowulei in Mende, is a forest-dwelling duiker found in the southern parts of Liberia, southwestern Côte d'Ivoire, and scattered enclaves in Sierra Leone. It is named in honor of Fredericus Anna Jentink.
The Maxwell's duiker is a small antelope found in western Africa.
The red-flanked duiker is a species of small antelope found in western and central Africa in countries as far apart as Senegal and Sudan. Red-flanked duikers grow to almost 15 in (35 cm) in height and weigh up to 31 lb (14 kg). They have russet coats, with greyish-black legs and backs, and white underbellies. They feed on leaves, fallen fruits, seeds and flowers, and sometimes twigs and shoots. The adults are territorial, living in savannah and lightly wooded habitats, and the females usually produce a single offspring each year. They have lifespans of ten to fifteen years in captivity.
The zebra duiker is a small antelope found primarily in Liberia, as well as the Ivory Coast, Sierra Leone, and occasionally Guinea. They are sometimes referred to as the banded duiker or striped-back duiker. It is believed to be one of the earliest duiker species to have evolved.
The yellow-backed duiker is a forest dwelling antelope in the order Artiodactyla from the family Bovidae. Yellow-backed duikers are the most widely distributed of all duikers. They are found mainly in Central and Western Africa, ranging from Senegal to Western Uganda with possibly a few in Gambia. Their range also extends southward into Rwanda, Burundi, Zaire, and most of Zambia.
The Upper Guinean forests is a tropical seasonal forest region of West Africa. The Upper Guinean forests extend from Guinea and Sierra Leone in the west through Liberia, Côte d'Ivoire and Ghana to Togo in the east, and a few hundred kilometers inland from the Atlantic coast. A few enclaves of montane forest lie further inland in the mountains of central Guinea and central Togo and Benin.
Benin has varied resources of wildlife comprising flora and fauna, which are primarily protected in its two contiguous protected areas of the Pendjari National Park and W National Park. The former is known for many species of avifauna and the latter park is rich in mammals and predators. In addition, many other forest reserves are noted in the country but are not easily accessible, well protected or adequately surveyed for its wildlife resources. The protected area system of Benin defined as National Protected Area System is situated in the northern Benin, mostly with a woody savanna ecosystem. It covers 10.3% of the national territory and is part of the three nation transboundary W-Arly-Pendjari (WAP) complex.
The forest giant squirrel or Stanger's squirrel is a species of rodent in the family Sciuridae found in Angola, Benin, Burundi, Cameroon, the Central African Republic, the Republic of the Congo, the Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Gabon, Ghana, Kenya, Liberia, Nigeria, Rwanda, Sierra Leone, Tanzania, Togo, and Uganda. Its natural habitats are subtropical or tropical moist lowland forests and plantations.
The wildlife of Togo is composed of the flora and fauna of Togo, a country in West Africa. Despite its small size the country has a diversity of habitats; there are only remnants of the once more extensive rain forests in the south, there is Sudanian Savanna in the north-western part of the country and larger areas of Guinean forest-savanna mosaic in the centre and northeast. The climate is tropical with distinct wet and dry seasons. There are estimated to be over 3000 species of vascular plant in the country, and 196 species of mammal and 676 species of bird have been recorded there.
Philantomba is a mammal genus which contains three species of duiker, a type of small antelope. The three species are Maxwell's duiker, the blue duiker and the Walter's duiker.
Walter Verheyen's African dormouse is a monotypic species of rodent in the family Gliridae. From the Central Congolian lowland forests ecoregion in the central Congo Basin, it has been found in west-central Democratic Republic of the Congo, in the vicinity of the Lukenie River and of Wafania, near the left bank of the Luilaka River. Although not found in immediate association, Lorraine's dormouse and the short-eared African dormouse are understood to be "broadly sympatric". Most closely resembling Jentink's dormouse, it differs from this species both in its much smaller size and in its relative proportions. On the IUCN Red List, its conservation status has been assessed as Data Deficient.
