Otters are a semi-aquatic mammal with brown fur and a creamy buff coloured belly. Often described as inquisitive, playful and intelligent, they live along river banks, lake edges and sea coasts in holes called holts.
Otters love to eat fish, but they will also take small birds, rodents and in spring even frogs. Their eyes are high on the head so that the rest of the body can remain underwater. With their webbed feet and streamline shape otters are naturally fast and agile swimmers. Underwater they appear silvery in colour, due to bubbles of air trapped in the fur.
Happily populations of otters are now growing again thanks to our cleaner rivers. A tell-tale sign that otters are about is finding their droppings (called spraints) which can be near water. will usually contain fish bones and can be very oily and smelly.
Otters are a secretive and protected species. Find out how you could help the otter by contacting your local Wildlife Trust.

We were able to film this otter using our remote camera. Judging by your messageboard posts the otters are proving very elusive.
