Good to know
Six things about the otter
ReturnBack from the brink
Otters almost vanished from England in the 1970s. Cleaner rivers have let them return to every county.
FurThe thickest coat
An otter's fur is so dense that water never reaches its skin.
HomeA holt
An otter's den is called a holt. It is often among tree roots on the bank.
SignsSpraint
Otter droppings are called spraint. They are left on rocks as messages, and are said to smell of jasmine tea.
SwimmingBuilt for water
Webbed feet, a strong tail, and ears and nostrils that close underwater make the otter a superb swimmer.
FoodFish supper
Otters eat mostly fish, especially eels, along with frogs and crayfish.
The real thing

Out and aboutHow to spot one
Look on rocks and under bridges for tarry droppings full of fish bones, and for five-toed prints in mud. Then wait at dawn or dusk.
Lend a handHow to help
Keep dogs out of the water in quiet stretches, take fishing line and litter home, and report sightings to your local wildlife trust.
