Least weasels driven from a mountain hare carcass by a stoat, as illustrated in Barrett-Hamilton's A History of British Mammals. The least weasel is small enough to be preyed upon by a range of other predators. [38] Least weasel remains have been found in the excrement of red foxes, sables, steppe and forest polecat, stoats, eagle owls and ...
Range maps are provided wherever possible; if a range map is not available, a description of the mustelid's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted. All extinct species or subspecies listed alongside extant species went extinct after 1500 CE, and are indicated by a dagger symbol ...
In the UK, the term "weasel" usually refers to the smallest species, the least weasel (M. nivalis), [1] the smallest carnivoran species. [ 2 ] Least weasels vary in length from 173 to 217 mm ( 6 + 3 ⁄ 4 to 8 + 1 ⁄ 2 in), [ 3 ] females being smaller than the males, and usually have red or brown upper coats and white bellies; some populations ...
Sthenictis sp. (American Museum of Natural History). Mustelids vary greatly in size and behaviour. The smaller variants of the least weasel can be under 20 cm (8 in) in length, while the giant otter of Amazonian South America can measure up to 1.7 m (5 ft 7 in) and sea otters can exceed 45 kg (99 lb) in weight.
The elk or wapiti (Cervus canadensis) is one of the largest species of deer in the world and one of the largest mammals in North America and eastern Asia. In the deer family ( Cervidae ), only the moose , Alces alces (called an "elk" in Europe), is larger, and Cervus unicolor (the sambar deer) can rival the C. canadensis elk in size.
Weasels are mammals belonging to the family Mustelidae and the genus Mustela, which includes stoats, least weasels, ferrets, and minks, among others. Different species of weasel have lived alongside humans on every continent except Antarctica and Australia, and have been assigned a wide range of folkloric and mythical meanings.
The American mink (Neogale vison) is a semiaquatic species of mustelid native to North America, though human introduction has expanded its range to many parts of Europe, Asia, and South America. Because of range expansion, the American mink is classed as a least-concern species by the IUCN. [1]
Mustelinae is a subfamily of family Mustelidae, including weasels, ferrets, and minks. [ 1 ] [ 2 ] It was formerly defined in a paraphyletic manner to also include wolverines , martens , and many other mustelids, to the exclusion of the otters ( Lutrinae ).
