Lutra species are semiaquatic mammals, so are well-adapted to both water and land. They prefer shallow, narrow areas of streams surrounded by mature trees and with rocks, especially where weirs reduce the flow of the water, as well as attract fishes. They seem to tolerate roads, residential and agricultural areas, but only moderate human interaction. They clearly avoid areas without vegetation cover and rocks.
The otters' diets consist mainly of fish (hence, the aquatic environment). 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 have also feed on plants, specifically grasses. With this large diversity of prey and resources for their diets, otters are considered "opportunistic eaters".
Otters most commonly live in solitude (away from other otters).
