However, during the winter and in colder environments, fish consumption is significantly lower and the otters use other resources for their food supply. Their diets can consist of amphibians (mainly frogs and pond turtles), bird predation (mainly anserine species), small rodents , and invertebrates such as water beetles, snails, and crayfish.
They range in size from the least shrew tenrec, at 4 cm (2 in) plus a 6 cm (2 in) tail, to the giant otter shrew, at 34 cm (13 in) plus a 39 cm (15 in) tail. Afrosoricids primarily eat invertebrates , particularly insects and earthworms, though some will also eat small lizards or other vertebrates.

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.
