Everglades-Otter Otter Florida otters have very beautiful brown fur, the male is slightly larger and darker. An otter is about the size of a cat.
Otters are very good swimmers which is good because they mostly eat fish.
The otter is not a fussy eater. It will eat small land animals, such as muskrats, shrews, and young beavers. But it catches most of its food in the Everglades waters. An otter will eat almost anything that swims or floats - fish, frogs, tadpoles, turtles, insects, even ducks and other birds. Perhaps its favorite treats are the crayfish that live on the bottom of rivers and ponds.
