Theswamp musk shrew (Crocidura mariquensis), ormusk shrew,[2] is a species ofmammal in the familySoricidae. It occurs inAngola,Botswana,Democratic Republic of the Congo,Mozambique,Namibia,South Africa,Eswatini,Zambia andZimbabwe. Its natural habitat is swamps, and it is a common species in suitable habitats, with theInternational Union for Conservation of Nature listing it as being of "least concern".[1]
This is a moderate-sized shrew growing to a head-and-body length of about 80 mm (3 in) with a tail of around 60 mm (2.4 in), males being slightly larger than females. The head is long and narrow, with a sharply pointed snout, small eyes and rounded ears. The dorsal pelage is blackish-brown tinged with rust, the individual hairs having greyish bases, brownish bands and brownish-black tips. The ventral surface is paler greyish-brown, there being no clear demarcation between dorsal and ventral fur. The tail is about 70% of the head-and-body length, and is partially haired and some shade of brown, sometimes paler below. Both fore and hind feet are yellowish-brown, reddish-brown or dark brown, and the digits of the hind feet splay apart when the animal is walking. There is considerable variation in colouring over the shrew's range.[2]
The musk shrew is native to southern Africa, where its range extends fromAngola and the southernDemocratic Republic of the Congo, throughZambia, northeasternNamibia and northernBotswana, toZimbabwe, southernMozambique,Eswatini and northeasternSouth Africa. It has a requirement for a wetland habitat and occurs inreed beds and semi-aquatic vegetation, in the vicinity of rivers and lakes and in seasonally flooded areas, with a marked preference formarshes andswamps.[1]
The musk shrew is mainlynocturnal, although it may occasionally be active during the day.[2] It clambers around among the aquatic vegetation with agility; it is not aggressive to other members of its species and does not scent mark its surroundings. In captivity it will feed onsnails andtermites, but does not dig into the ground to forage. In its natural surroundings, nests have been observed in grass tussocks and in debris above the surface of the ground. Breeding mostly takes place in the wet season, with litters averaging three to four young. It ispredated upon by thesouthern fiscal, thebarn owl and theAfrican grass owl.[2]
This shrew was classified as "near threatened" in 2016 bySouth African National Bioinformatics Institute;[3] however, it has a wide range, is presumed to have a stable and large total population, and faces no particular threats, so theInternational Union for Conservation of Nature has assessed its conservation status as being of "least concern".[1]
