Several otter species live in cold waters and have high metabolic rates to help keep them warm. Eurasian otters must eat 15% of their body weight each day, and sea otters 20 to 25%, depending on the temperature. In water as warm as 10 °C (50 °F), an otter needs to catch 100 g (3.5 oz) of fish per hour to survive.
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.
