The European Otter, Lutra lutra, also known as the Eurasian River Otter, Common Otter, and Old World Otter, is a European member of the Mustelidae or weasel family, and is typical of freshwater otters. For the rest of this article 'otter' will refer specifically to the European otter, although the information may be applicable to other otter species.

Range and habitat

The European otter is the most widely distributed otter species, the name being something of a misnomer, as the species' range includes parts of Asia and Africa, as well as being spread across Europe. The otter is believed to be extinct in Liechtenstein, the Netherlands, and Switzerland. Otters are now very common along the coast of Norway and in Northern Britain, especially Shetland where 12% of the UK breeding population exist.[citation needed] In Italy, they can be found in the Calore river area.

An otter's diet mainly consists of fish but can also include birds, insects, frogs, crustaceans and sometimes small mammals. In general this opportunism means they may inhabit any unpolluted body of freshwater, including lakes, streams, rivers, and ponds, as long as there is good supply of food. Otters may also live along the coast, in salt water, but require regular access to freshwater to clean their fur. For other uses, see Bird (disambiguation). ...

Behaviour and reproduction

Otters are strongly territorial, living alone for the most part, with individual's home ranges varying between 1-40 km, with about 18 km being usual, depending on the density of food available. Males and females will breed at any time of the year when mating takes place in water. After a gestation period of about 63 days 1-4 pups are born, which remain dependent on the mother for a year. The male plays no role in parental care, because a few days before the young otters are born, the female otter begins to bite her partner until the male otter leaves. Otherwise the male otter would probably eat his young generation, because he is not able to tell the difference between rats and new born otters.


Hunting mainly takes place at night, while the day is usually spent in the otter's 'holt', a burrow in the riverbank which can only be entered from underwater.


Conservation

The European otter declined acrosss its range in the second half of the 20th Century [1] primarily due to pollution from pesticides such as organochlorine pesticides (OCs) and polychlorinated biphenyls (PCBs) [2]. Other threats included habitat loss and hunting, both legal and illegal[3] Image File history File linksMetadata Download high-resolution version (1280x960, 666 KB) A pair of otters in a wildlife sanctury I, the creator of this work, hereby grant the permission to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1. ...

Otter populations are now recovering in many parts of Europe for example in Britain the number of sites with an otter presence increased by 55% between 1994 and 2002 [4].


Recovery is partly due to a ban on the most harmful pesticides that has been in place across Europe since 1979 [5]and partly to direct legal protection under the European Union Habitats Directive.[6] and national legislation in several European countries [7][8] [9]

European Otters in popular culture

The novels Ring of Bright Water and Tarka the Otter, and the films based on them, each feature European Otters. The Redwall series of books by Brian Jacques also regularly features anthropomorphic otters among its characters, also titling one of his books The Pearls of Lutra. Ring of Bright Water is a 1960 autobiographical book by Gavin Maxwell and a 1969 film, loosely based on the book, starring Bill Travers and Virginia McKenna. ...

Otter (575 words)
Otters are aquatic or marine carnivorous mammals, members of the large and diverse family, Mustelidae, which also includes weasels, polecats[?], badgers and others.
Otters have a dense layer of very soft underfur (almost half a million hairs per square inch of skin) which, protected by their outer layer of long guard hairs, keeps them dry under water and traps a layer of air to keep them warm.
To survive in the cold waters where many otters live, the specialised fur is not enough: otters have very high metabolic rates and burn up energy at a profligate pace: Eurasian Otters[?], for example, must eat 15% of their body weight a day; Sea Otters[?], 20 to 25%, depending on the temperature.
