Otter Lutra lutra

Otters are one of our top predators, feeding mainly on fish, waterbirds, amphibians and crustaceans. Otters have their cubs in underground burrows, known as a 'holt'. Excellent and lithe swimmers, the young are in the water by 10 weeks of age. Otters are well suited to a life on the water as they have webbed feet, dense fur to keep them warm and can close their ears and nose when underwater. For the best chances of seeing an otter in the wild, try the west coast of Scotland, the Shetland Islands or some parts of Wales, northern England and East Anglia.

Otters can be distinguished from Mink by their much larger size, more powerful body, paler grey-brown fur, broader snout and broader, pale chest and throat.

Facts

Seeing the signs of otters is far easier than seeing the animals themselves. Along riverbanks and waterways, look for five-toed footprints (about 6-7cm long) and droppings or 'spraints'. Otters leave spraints in prominent places, such as fallen trees, weirs and bridges, as 'scented messages', helping them to find mates and defend territories. They contain visible fish bones and have a distinctive, pleasant smell, reminiscent of Jasmine tea!
