The marsh mongoose (Atilax paludinosus), also called water mongoose [1] [2] is a medium-sized mongoose species native to sub-Saharan Africa that inhabits freshwater wetlands. It has been listed as Least Concern on the IUCN Red List since 2008. [1]
The generic name Atilax was introduced in 1826 by Frédéric Cuvier. [3] In 1829, Georges Cuvier referred to a mongoose in the marshes of the Cape Province using the scientific name Herpestes paludinosus. [4] It is the only extant member of the genus Atilax, [5] although an extinct ancestral species from the Early Pleistocene known as Atilax mesotes was also a member of the genus. [6]
The marsh mongoose's fur is dark reddish brown to black with white and fawn coloured guard hairs. The hair behind the neck and in front of the back is short, but longer on the hind legs and on the tail. Its muzzle is short with a fawn coloured mouth, short whiskers and a naked rhinarium. It has 3.1.3.23.1.3.2 × 2 = 36 teeth. Its short ears are round. It has two nipples. Its feet have five flexible digits each with curved claws, but without any webbing. The soles of its feet are naked. [7]
Females measure 48.72 cm (19.18 in) in head-to-body length, and males 51.38 cm (20.23 in), with a 32.18–34.11 cm (12.67–13.43 in) long tail. In weight, adults range from 2.56 to 2.95 kg (5.6 to 6.5 lb). Both sexes have anal glands in a pouch that produce a musky smelling secretion. [8]
Female marsh mongooses have 36 chromosomes, and males 35, as one Y chromosome is translocated to an autosome. [9]
The marsh mongoose occurs across much of sub-Saharan Africa from Senegal and The Gambia to Ethiopia, and throughout much of Central, Eastern and parts of Southern Africa. [1] It inhabits freshwater wetlands, marshes and swamps along slow-moving rivers and streams, in forested, jungle and savanna regions. It is occurs in river deltas, estuarine and brackish-water habitats in coastal areas. [7] It was likely introduced by humans to Pemba Island in the Zanzibar Archipelago. [10]
In Guinea's National Park of Upper Niger, it was recorded during surveys conducted in 1996 to 1997. [11] In Gabon's Moukalaba-Doudou National Park, it was recorded only in forested habitats during a two-months survey in 2012. [12]
In the Ethiopian Highlands, it was recorded at an elevation of 3,950 m (12,960 ft) in Bale Mountains National Park. [13]
The marsh mongoose is primarily a solitary species. [2] It is an excellent swimmer and can dive for up to 15 seconds, using its feet to paddle. On land, it usually trots slowly, but can also move fast. [14] Radio-collared marsh mongooses in KwaZulu-Natal were active from shortly after sunset until after midnight showing a crepuscular activity pattern. [15] A radio-collared male marsh mongoose in Dzanga-Sangha Special Reserve was most active during early mornings and late evenings, but rested by day in burrows situated in dry areas above water and mud in a dense cover of high grasses and climbing plants. [16]
Feeding behaviour of eight captive marsh mongooses was studied in 1984. When the mongooses sighted prey in the water, they swam or walked towards it, used their digits to seek it out, but kept their heads above water. Once located, they grabbed it with the mouth and killed it outside the water. They killed rodents and frogs by biting them in the head, and occasionally also shook them. When finished eating, they wiped their mouths with the forefeet. They broke eggs by throwing them backwards between the legs. [2] Scat of marsh mongooses collected around Lake St Lucia contained foremost remains of crustaceans, amphibians, insects and fish. Marsh mongooses were observed while carrying mudcrabs (Scylla serrata) ashore. They removed the chelipeds and opened the sternum to feed on the body contents. [17] They deposit scat at specific latrine sites located on low shrubs, on rocks or sand well away from the water edge. Scat of marsh mongoose collected in a rocky coastal habitat contained remains of sandhoppers, shore crab (Cyclograpsus punctatus), pink-lipped topshell ( Oxystele sinensis ) and Tropidophora snails. [18] Research in southeastern Nigeria revealed that the marsh mongoose has an omnivorous diet. It feeds on rodents like giant pouched rats (Cricetomys), Temminck's mouse (Mus musculoides), Tullberg's soft-furred mouse (Praomys tulbergi), grass frogs (Ptychadena), crowned bullfrog (Hoplobatrachus occipitalis), herald snake ( Crotaphopeltis hotamboeia ), mudskippers (Periophthalmus), insects such as spiders and Coleoptera, snails and slugs, Bivalvia, Decapoda as well as fruits, berries and seeds. [19]
After a gestation of 69 to 80 days, females give birth to a litter of two to three young, which are fully furred. Their eyes open between the 9th and 14th day, pupils are bluish at first and change to brown at the age of three weeks. Their ear canal opens between the 17th and 28th day. Females start weaning their offspring earliest on the 30th day, and young are fully weaned by the age of two months. [20]
In 2006, it was estimated that about 950 marsh mongooses are hunted annually in the Cameroon part of the Cross–Sanaga–Bioko coastal forests. [21]
A mongoose is a small terrestrial carnivorous mammal belonging to the family Herpestidae. This family is currently split into two subfamilies, the Herpestinae and the Mungotinae. The Herpestinae comprises 23 living species that are native to southern Europe, Africa and Asia, whereas the Mungotinae comprises 11 species native to Africa. The Herpestidae originated about 21.8 ± 3.6 million years ago in the Early Miocene and genetically diverged into two main genetic lineages between 19.1 and 18.5 ± 3.5 million years ago.
The yellow mongoose, sometimes referred to as the red meerkat, is a member of the mongoose family. It averages about 0.45 kg (1 lb) in weight and about 510 mm (20 in) in length. It lives in open country, semi-desert scrubland and grasslands in Angola, Botswana, South Africa, Namibia, and Zimbabwe. It is the only species in the genus Cynictis.
Atilax is a genus of mongoose containing a single living species, the marsh mongoose (Atilax paludinosus). A single fossil species probably ancestral to the marsh mongoose is also known from South Africa.
The stripe-necked mongoose is a mongoose species native to forests and shrublands from southern India to Sri Lanka.
A genet is a member of the genus Genetta, which consists of 17 species of small African carnivorans. The common genet is the only genet present in Europe and occurs in the Iberian Peninsula, Italy and France.
The crab-eating mongoose is a mongoose species ranging from the northeastern Indian subcontinent and Southeast Asia to southern China and Taiwan. It is listed as Least Concern on the IUCN Red List.
The Egyptian mongoose, also known as ichneumon, is a mongoose species native to the tropical and subtropical grasslands, savannas, and shrublands of Africa and around the Mediterranean Basin in North Africa, the Middle East and the Iberian Peninsula. Whether it is introduced or native to the Iberian Peninsula is in some doubt. Because of its widespread occurrence, it is listed as Least Concern on the IUCN Red List.
The golden palm civet is a viverrid endemic to Sri Lanka. It is listed as Vulnerable on the IUCN Red List. Its distribution is severely fragmented, and the extent and quality of its habitat in Sri Lanka's hill regions are declining.
The long-nosed mongoose is a mongoose native to Central African wetlands and rainforests. It has been listed as Least Concern on the IUCN Red List since 1996. Although formerly classified in Herpestes, more recent studies indicate that it belongs in the monotypic taxon Xenogale.
The white-tailed mongoose is a species in the mongoose family Herpestidae. It is the only member of the genus Ichneumia.
Herpestes is a genus within the mongoose family Herpestidae. Several species in the family are known as slender mongooses. It is the type genus of the family, and comprises 5-6 living species, each with several subspecies. Fossil remains of three prehistoric species were excavated in France, and described in 1853.
Potamonautes sidneyi is a species of freshwater crab in the family Potamonautidae. The common name is the Natal river crab or Sidney's river crab, although they may also be referred to as "river crabs", "fresh water crabs" or "land crabs".
The small Indian mongoose is a mongoose species native to Iraq and northern South Asia; it has also been introduced to several Caribbean and Pacific islands.
Urva is a genus comprising the Asian mongooses within the mongoose family Herpestidae. Species in the genus were formerly classified in the genus Herpestes, which is now thought to comprise exclusively African mongooses; phylogenetic evidence indicates that the Asian mongooses form a monophyletic group and had an Asian common ancestor. Urva forms a clade with Xenogale and Atilax, while Herpestes forms a clade with all other African mongoose species.
Atilax mesotes is an extinct species of mongoose that lived in Africa during the Early Pleistocene around 1.98 million years ago.
