mongoose, any of nearly three dozen species of small bold predatory carnivores found mainly in Africa but also in southern Asia and southern Europe. Mongooses are noted for their audacious attacks on highly venomous snakes such as king cobras. The 33 species belong to 14 genera. The most common and probably best-known are the 10 species of the genus Herpestes, among which are the Egyptian mongoose, or ichneumon (H. ichneumon), of Africa and southern Europe and the Indian gray mongoose (H. edwardsi), made famous as Rikki-tikki-tavi in Rudyard Kipling’s The Jungle Books (1894 and 1895). The meerkat (Suricata suricatta) is also a member of the mongoose family. The colloquial term mongoose may also include Malagasy mongooses—a group of five species found on the island of Madagascar that are closely related to fossas, falanoucs, and fanalokas (the Malagasy civet) and which most sources classify within the family Eupleridae.
Mongooses are short-legged animals with pointed noses, small ears, and long furry tails. The claws do not retract, and in most species there are five toes on each foot. The fur is gray to brown and is commonly grizzled or flecked with lighter gray. Markings, when present, include stripes, dark legs, and pale or ringed tails. The adult size varies considerably, with the smallest being the dwarf mongoose (Helogale parvula), which measures 17–24 cm (7–10 inches) with a 15–20-cm (approximately 6–8-inch) tail. The largest mongoose is the white-tailed mongoose (Ichneumia albicauda), whose body length measures 48–71 cm (about 19–28 inches) long with a tail that may extend up to an additional 47 cm (18.5 inches).
Natural history
Mongooses live in burrows and feed on small mammals, birds, reptiles, eggs, and occasionally fruit. A number of mongooses, especially those of the genus Herpestes, will attack and kill venomous snakes. They depend on speed and agility, darting at the head of the snake and cracking the skull with a powerful bite. Mongooses are bitten occasionally; however, they possess a glycoprotein that binds to proteins in snake venom, deactivating them and making them harmless.
A number of species are noted for their peculiar habit of opening eggs as well as other food items with hard shells (crabs, mollusks, and nuts). The animal stands on its hind legs and hits the egg against the ground. Sometimes it carries the egg to a rock and, standing with its back to the rock, throws the egg between its legs and against the rock until the shell is broken. Early reports of this behaviour met with skepticism but have been verified by other observers. The Malagasy narrow-striped mongoose (Mungotictis decemlineata) exhibits the same behaviour but lies on its side and uses all four feet to toss the egg.
Most species are active during the day and are terrestrial, although the marsh mongoose (Atilax paludinosus) and a few others are semiaquatic. Some mongooses live alone or in pairs, but others, such as the banded mongoose (Mungos mungo), dwarf mongooses (genus Helogale), and meerkats, live in large groups. Litters usually consist of two to four young.
Some species, mainly the Javan mongoose (Herpestes javanicus) but also the Indian gray mongoose, were introduced to numerous islands, including Mafia Island (off the coast of East Africa), Mauritius, and those of Croatia, Hawaii, and Fiji. Originally intended to help control rodents and snakes, these introductions were disastrous, because the mongooses severely depleted the populations of native fauna. Because of their potential destructiveness, importation of all mongooses into the United States is strictly regulated.
Classification
The presence of an anal scent gland and associated sac is one of the most important anatomical features that differentiates mongooses from members of the family Viverridae—the group of small Old World mammals that contains civets, genets, and linsangs—in which they were formerly classified. The classification below considers the carnivore families Herpestidae and Eupleridae and their subdivisions. According to most classifications, mongooses span family Herpestidae and the Galidiinids (Malagasy mongooses) of family Eupleridae. The euplerid subfamily Euplerinae—made up of fossas, falanoucs, and fanalokas—is also included below; these animals are related to Malagasy mongooses, but they are not considered mongooses.
