Weasels feed on small mammals and have from time to time been considered vermin because some species took poultry from farms or rabbits from commercial warrens. They do, on the other hand, eat large numbers of rodents. Their range spans Europe, North America, much of Asia and South America, and small areas in North Africa.
The least weasel is the product of a process begun 5–7 million years ago, when northern forests were replaced by open grassland, thus prompting an explosive evolution of small, burrowing rodents. The weasel's ancestors were larger than the current form, and underwent a reduction in size to exploit the new food source.

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.
They typically eat about 100–120 grams (3.5–4.2 oz) of food daily, and cache excess food. [6] In urban areas in China, Siberian weasels prey extensively on rats. They are capable of killing and dragging the largest fowls. [7] Siberian weasels are active hunters and chase prey through snow, logs, water and people's houses. [3] [8]
Opposable thumbs enable humans to do tasks that most animals can’t even attempt – from eating food easily to driving a car. You may not realize that we are not alone with our amazing thumbs ...
It is a long, slender-bodied weasel, with fur ranging from yellowish to brown to near black. It may be confused with the fisher (Pekania pennanti), but the marten is lighter in color and smaller. Identification of the marten is further eased by a characteristic bib that is a distinctly different color than the body.
