(Galerella sanguinea)
The common slender mongoose (Herpestes sanguineus), also known as the black-tipped mongoose or the black-tailed mongoose, is a very common mongoose species native to sub-Saharan Africa. The scientific name Herpestes sanguineus was proposed by Eduard Rüppell in 1835 who described a reddish mongoose observed in the Kordofan region. The common 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 common 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.
