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.
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.

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]
Japanese weasels are prey to some larger animals. Foxes, martens, preying birds and domestic cats hunt Japanese weasels and pose a threat to their life. [5] Despite this, Japanese weasels are known to hunt prey larger than them such as rabbits. Even as prey, rabbits pose a threat to weasels and are capable of kicking and dragging in defence. [11]
