The river otter (Lutra canadensis)  is  a long, elongated water-loving animal found throughout Florida except the Keys.     Its legs are short and has webbed toes for swimming.  The ears are appear large on it's small flattened head.   River otters seem to prefer fresh water, and can be in rivers, creeks, lakes, ponds, and swamps.  Otters live in burrows on the bank of the water body, often under the roots of a tree.  They may dig their own burrow, or remodel the burrow of a beaver.  They normally feed on animals such as crayfish and fish.  If you have a fish pond an otter may find it.

The best way to control the otter is to exclude the otter from pond with fencing or a cover.   This will also prevent other animals such as raccoons, or some birds from finding the goldfish, which are an easy prey item for many species.  Problems otters may be trapped and relocated but permits from the FWC are required from the regional office.
