Marine Otter

Unlike other coastal otters, like the Eurasian otter, once it has been in salt water the Marine otter doesn’t need to clean its fur in fresh water. The Marine otter has different, more rigid, fur that protects it against rocks if it is fishing in rough waters.

Otters Around the World

Find out all about information on otters in certain countries. Please note, there are no wild otter populations in Australasia* and Antarctica.

*Otters are said to be absent from Australasia. However, New Zealand was reported to have an indigenous mammal living in the rivers and lakes of South Island when the first European settlers came in 1777. In 1851 the Maoris described an animal resembling an otter or badger and in 1861 Julian Haast wrote "I frequently saw tracks which resembled a European otter".

By the 1950s it was concluded that there was very little evidence to say that this animal ever existed, although a little doubt still remains and we should not ignore the possibility, however small.
