Arctocebus
Angwantibos are two species of strepsirrhine primates classified in the genus ''Arctocebus'' of the family Lorisidae. They are also known as golden pottos because of their yellow or golden coloration. Angwantibos live in tropical Africa and their range includes Nigeria, Cameroon north of the Democratic Republic of Congo. Angwantibos grow to a size of 22 to 30 cm, and have almost no tail at all. They only weigh up to 0.5 kg. Their fur is yellow brown to golden in color. Their snout is more pointed than that of the other lorids and this, along with their round ears, gives it the bear-like appearance that lends them their name in German: ''Bärenmaki'', "bear lemur". Solitary, nocturnal and arboreal, they prefer the underbrush and the lower layers of the forests. They spend the day hidden in the leaves. Like all lorisids they are characterized by slow movements. The diet of angwantibos consists predominantly of insects (mostly caterpillars), and occasionally fruits. Owin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calabar Angwantibo
The Calabar angwantibo (''Arctocebus calabarensis''), also known as the Calabar potto, is a strepsirrhine primate of the family Lorisidae. It shares the genus ''Arctocebus'' with the golden angwantibo (''Arctocebus aureus''). It is closely related to the potto (''Perodicticus potto'') and to the various lorises. The Calabar angwantibo lives in the rainforests of west Africa, particularly in tree-fall zones. In areas where the forest has been cleared, it has been known to live on farmland. Its range covers Cameroon, Nigeria and Equatorial Guinea. The species takes its name from the Nigerian city of Calabar. The Calabar angwantibo weighs between 266 and 465 grams. It has orangish-yellow fur on its back, grey or white fur on its belly, and a distinctive white line on its forehead and nose. Like other lorids, this angwantibo has a very short index finger, which allows it to get a strong grip on tree branches. The second toe on each foot has a specialised claw that the angwantibo us ...

Arctocebus Aureus
The golden angwantibo (''Arctocebus aureus'') is a strepsirrhine primate of the family Lorisidae. It shares the genus ''Arctocebus'' with the Calabar angwantibo (''Arctocebus calabarensis'') and together they are commonly called the golden pottos. The golden angwantibo is found in Cameroon, the Republic of Congo, Equatorial Guinea and Gabon. Its usual habitat is rain forest, but it has also been known to live on farmland. Like the Calabar angwantibo, the golden angwantibo weighs between 266 and 465 grams and has a stumpy tail, abbreviated index fingers, a specialised grooming claw on each foot and a white line on its face. It can be distinguished from its cousin largely by its colour. The fur on its back is red-gold, with a more muted red on its belly. Unlike the Calabar angwantibo, the golden angwantibo has no nictitating membrane. The golden angwantibo is a nocturnal and arboreal species that is typically found on small branches 5–15 metres above ground. Its diet consists ...

Arboreal
Arboreal locomotion is the Animal locomotion, locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally, but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species.Cartmill, M. (1985). Climbing. In ''Functional Vertebrate Morphology'', eds. M. Hildebrand D. M. Bramble K. F. Liem and D. B. Wake, pp. 73–88. Cambridge: Belknap Press. Furthermore, many of these same principles may be applied to climbing without trees, such as on rock piles or mountains. Some animals are exclusively arboreal in habitat, such as the tree snail. Biomechanics Arboreal habitats pose numerous mechanical challenges to animals moving in them, which have been solved in diverse ways. These challenges include moving on n ...

Mammals Of Cameroon
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...

Lorises
Loris is the common name for the strepsirrhine mammals of the subfamily Lorinae (sometimes spelled Lorisinae) in the family Lorisidae. ''Loris'' is one genus in this subfamily and includes the slender lorises, ''Nycticebus'' is the genus containing the slow lorises, and ''Xanthonycticebus'' is the genus name of the pygmy slow loris. Description Lorises are nocturnal and arboreal. They are found in tropical and woodland forests of India, Sri Lanka, and parts of southeast Asia. Loris locomotion is a slow and cautious climbing form of quadrupedalism. Some lorises are almost entirely insectivorous, while others also include fruits, gums, leaves, and slugs in their diet. Female lorises practice infant parking, leaving their infants behind in trees or bushes. Before they do this, they bathe their young with allergenic saliva that is acquired by licking patches on the insides of their elbows, which produce a mild toxin that discourages most predators, though orangutans occasionally ea ...

The Overloaded Ark
''The Overloaded Ark'', first published in 1953, is the debut book by British naturalist Gerald Durrell. It is the chronicle of a six-month collecting trip, from December 1947 to August 1948, to the West African colony of British Cameroonnow Cameroonthat Durrell made with aviculturist and ornithologist John Yealland. Their reasons for going on the trip were twofold: "to collect and bring back alive some of the fascinating animals, birds, and reptiles that inhabit the region", and secondly, for both men to realise a long cherished dream to see Africa. Its combination of comic exaggeration and environmental accuracy, portrayed in Durrell's light, clever prose, made it a great success. It launched Durrell's career as a writer of both non-fiction and fiction, which in turn financed his work as a zookeeper and conservationist. '' The Bafut Beagles'' and ''A Zoo in My Luggage'' are sequels of sorts, telling of his later returns to the region. History Durrell had married Jacqueline ...

Gerald Durrell
Gerald Malcolm Durrell, (7 January 1925 – 30 January 1995) was a British naturalist, writer, zookeeper, conservationist, and television presenter. He founded the Durrell Wildlife Conservation Trust and the Jersey Zoo on the Channel Island of Jersey in 1959. He wrote approximately forty books, mainly about his life as an animal collector and enthusiast, the most famous being ''My Family and Other Animals'' (1956). Those memoirs of his family's years living in Greece were adapted into two television series (''My Family and Other Animals'', 1987, and ''The Durrells'', 2016–2019) and one television film (''My Family and Other Animals'', 2005). He was the youngest brother of novelist Lawrence Durrell. Early life and education Durrell was born in Jamshedpur, British India, on 7 January 1925. He was the fifth and youngest child (an elder sister having died in infancy) of Louisa Florence Dixie and Lawrence Samuel Durrell, both of whom were born in India of English and Irish ...

Copulation (zoology)
In zoology, copulation is animal sexual behavior in which a male introduces sperm into the female's body, especially directly into her reproductive tract. This is an aspect of mating. Many animals that live in water use external fertilization, whereas internal fertilization may have developed from a need to maintain gametes in a liquid medium in the Late Ordovician epoch. Internal fertilization with many vertebrates (such as all reptiles, some fish, and most bird Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweig ...s) occurs via cloacal copulation, known as cloacal kiss (see also hemipenis), while mammals copulate vaginally, and many primitive (biology), basal vertebrates reproduce sexually with external fertilization.

Territory (animal)
In ethology, territory is the sociographical area that an animal consistently defends against conspecific competition (or, occasionally, against animals of other species) using agonistic behaviors or (less commonly) real physical aggression. Animals that actively defend territories in this way are referred to as being territorial or displaying territorialism. Territoriality is only shown by a minority of species. More commonly, an individual or a group of animals occupies an area that it habitually uses but does not necessarily defend; this is called its home range. The home ranges of different groups of animals often overlap, and in these overlap areas the groups tend to avoid each other rather than seeking to confront and expel each other. Within the home range there may be a ''core area'' that no other individual group uses, but, again, this is as a result of avoidance. Function The ultimate function of animals inhabiting and defending a territory is to increase the indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
