The slender mongoose (Galerella sanguinea), also known as the black-tipped mongoose or the black-tailed mongoose, is a very common species of mongoose of sub-Saharan Africa. [2]

Range and habitat

The slender mongoose, with up to fifty subspecies, are found throughout sub-Saharan Africa, with the black mongoose of Angola and Namibia sometimes considered a separate species. They are adaptable and can live nearly anywhere in this wide range, but are most common in the savannah and semiarid plains. They are much rarer in densely forested areas and deserts.

As the name suggests, the slender mongoose has a lithe body of 27.5–40 cm (10.8–15.7 in) and a long tail of 23–33 cm (9–13 in). Males weigh 640–715 g (22.6–25.2 oz), while the smaller females weigh 460–575 g (16.2–20.3 oz).

The color of their fur varies widely between subspecies, from a dark reddish-brown to an orange red, grey, or even yellow, but these mongooses can be distinguished from other mongooses due to the prominent black or red tip on their tails. They also have silkier fur than the other African members of their family.

Behavior

The slender mongoose generally lives either alone or in pairs. It is primarily diurnal, although it is sometimes active on warm, moonlit nights. It doesn't seem to be territorial, but will nevertheless maintain stable home ranges that are often shared with members of related species. Indeed, the slender mongoose and these other species may even den together, as most of their relatives are nocturnal. Dens may be found anywhere sheltered from the elements: in crevices between rocks, in hollow logs, and the like.

Reproduction

A male's range will include the ranges of several females, and scent cues inform him when the female is in heat. The gestation period is believed to be 60 to 70 days, and most pregnancies result in one to three (usually two) young. The male does not help care for them. Unusually, for a solitary species, in the Kalahari the males are philopatric whereas the females disperse. [3] This is thought to be due to the benefits of kin cooperation by males in defence of females.

Feeding

The slender mongoose is primarily carnivorous, though it is an opportunistic omnivore. Insects make up the bulk of its diet, but lizards, rodents, snakes, birds, amphibians, and the occasional fruit are eaten when available. It will also eat carrion and eggs. As befits the popular image of mongooses, the slender mongoose is capable of killing and subsequently eating venomous snakes, but such snakes do not constitute a significant portion of its diet.

Slender mongooses are more adept at climbing trees than other mongooses, often hunting birds there.

Conservation

The slender mongoose has been targeted by extermination efforts in the past, due to its potential to be a rabies vector and the fact that it sometimes kills domestic poultry. These efforts have not been conspicuously successful, although some subspecies may be threatened.

Overall, the slender mongoose is in no immediate danger of extinction, and the IUCN Red List evaluated it as least concern. [4]

The East African oryx, also known as the beisa is a species of antelope from East Africa. It has two subspecies: the common beisa oryx found in steppe and semidesert throughout the Horn of Africa and north of the Tana River, and the fringe-eared oryx south of the Tana River in southern Kenya and parts of Tanzania. In the past, some taxonomists considered it a subspecies of the gemsbok, but they are genetically distinct; the diploid chromosome count is 56 for the beisa and 58 for the gemsbok. The species is listed as Endangered by the IUCN.

It lives in burrows, hedgerows and thickets, among groves of trees, and takes shelter under rocks or bushes and even in drains. It is very bold and inquisitive but wary, seldom venturing far from cover. It climbs very well. Usually found singly or in pairs. It preys on rodents, snakes, birds’ eggs and hatchlings, lizards and variety of invertebrates. Along the Chambal River it occasionally feeds on gharial eggs. It breeds throughout the year.

Black mongoose species of mammal

The black mongoose is a species of mongoose found in Namibia and Angola. Although originally described as a separate species by Thomas (1928), it has often been considered a subspecies of the slender mongoose. However, genetic analysis has confirmed its status as a separate species. Evidence suggests the two species diverged around four million years ago, likely due to some populations becoming separated as the habitat in southern Africa was changing. The black mongoose now occupies a distinct habitat in areas with large boulders and rocky outcrops known as inselbergs in the mountainous regions of northwest Namibia and southwest Angola. After remaining in these areas for millions of years, the black mongoose is highly specialized to survive in the harsh arid environment.
