The Cameroon Clawless Otter (Aonyx capensis congicus)[3] is a subspecies of the African Clawless Otter in the Mustelidae family.[1] It is found in Cameroon, Republic of the Congo, Democratic Republic of the Congo, Gabon, and possibly Angola, Burundi, Central African Republic, Equatorial Guinea, Nigeria, Rwanda, or Uganda.[2] Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, subtropical or tropical swamps, subtropical or tropical moist montanes, subtropical or tropical moist shrubland, subtropical or tropical seasonally wet or flooded lowland grassland, rivers, intermittent rivers, shrub-dominated wetlands, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, freshwater spring, inland deltas, saline lakes, intermittent saline lakes, saline marshes, intermittent saline marshes, shallow seas, subtidal aquatic beds, rocky shores, sandy shores, estuarine waters, intertidal flats, intertidal marshes, coastal saline lagoons, coastal freshwater lagoons, water storage areas, ponds, aquaculture ponds, seasonally flooded agricultural land, and canals and ditches. It is threatened by habitat loss.

Very little is known about this species. It is a small otter and found only in the mid-part of Africa, in the tropical belt. It is believed to spend much more time on land than other otters. Congo clawless otters are one of 13 species of otters in the carnivore family Mustelidae. Other members of this family include weasels, skunks, and ferrets. An individual otter maintains a territory. Otters mark their territories with scent, and fervently patrol and defend their territories.


ChaCongo clawless otters are characterized by only partial webbing (between the toes of their black feet and no webbing on their front feet), and small, blunt, peg-like claws. The have very sensitive forepaws, which they use for foraging. Other otters have fully webbed feet and strong, well-developed claws. Clawless otters have slender, serpentine bodies with dense, luxurious fur and long tails. All otters have been exploited for their thick, velvety fur. Their head and body length measure to be about 600-1,000 mm (24-39 in.), and their tail length is between 400 and 710 mm (16-28 in.). Also, these otters can weigh between 13 and 20 kg (29-44 lb.).


As far as their diet goes, the Congo clawless otters probably feed on fairly soft prey items such as small land vertebrates, frogs, and eggs.

Reproduction and Life span

Reproduction may occur throughout the year. Newborn cubs of A. congius are white in color and do not reach their adult color of brownish white until about 2 months old. life span is probably an average of 10–15 years.

Hunting and Conservation

Although otters are known to be difficult to catch, they are occasionally hunted for bushmeat and sold for similar prices of other bushmeat. Otter bushmeat is common in Congo and Cameroon but not for Gabon because of its reputation of being a dangerous. The myth in Gabon ist that otters can give electric shocks when caught with a spear. Otters are also thought to be magical and possess powers that when you catch an otter, skin it, and wear its fur, you are thought to become invisible to an enemy and are able to escape an enemy. The idea come from the otters ability to escape fish traps.Its fur is also used in Cameron to make drums. [4]

Species of otters are protected by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) - a worldwide treaty developed in 1973 to regulate trade in wildlife species. Due to commercial hunting for meat and fur, Congo clawless otter population numbers have undergone severe declines especially in Nigeria and Cameroon.
