The Otter is a shy and secretive marine mammal that can mainly be seen in the south west of England, as well as in some areas of the north east and the south east. It spends a lot of time in rivers and streams looking for food, but is very rarely seen because it mainly hunts for its food at night. However, if an Otter lives in the sea it may be seen more often.

The Otter has quite a long body and a long thickset tail. It has grey-brown fur and a big black nose that is the shape of a hexagon. It has a broad long face with long whiskers on either side and its mouth is set under its face just like the mouth of a shark.

On land Otters can look quite awkward when they walk because their back legs are longer than their front legs. However, in water Otters look elegant and graceful. When Otters want to swim fast, they keep their short front legs by their sides and use their back legs and powerful tails to propel themselves forward. Otters communicate in the water by whistling to each other. They often whistle when they want to find each other in dark waters. Otters eat lots of fish, but their favourite food is eels.
