- We know of 13 different species of otter in the world but only the Eurasian otter (Lutra lutra) is native to Britain.
- Eurasian otters are extremely widespread: they can be found in 81 countries throughout Europe, Asia, and Africa.
- Otters have the thickest fur of any mammal.
- The fur does not just keep them warm but also helps them stay buoyant by trapping air close to their skin.
- They can close their ears and nose when swimming.
- Their closest relatives are weasels.
- Otters are very vocal:
- Otter droppings are called spraint; they are used to communicate and mark territories. Those who know say that spraint smells like jasmine tea!
- This far south, otter pups can be born at any time of the year.
- The pups have to be taught to swim, usually when they are about two months old.
