The Eurasian otter, Lutra lutra, also known as the Eurasian river otter, common otter, Old World otter and European otter, is a European and Asian member of the Lutrinae or otter subfamily, and is typical of freshwater otters. For the rest of this article "otter" will refer specifically to the Eurasian otter.

Range and habitat

The Eurasian otter is the most widely distributed otter species, its range including parts of Asia and Africa as well as being spread across Europe. The otter is believed to be currently 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. For other uses, see Shetland (disambiguation). ... It has been suggested that this article or section be merged with Calore Lucano. ...


The 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. When living in the sea individuals of this species are sometimes referred to as "sea otters", but they should not be confused with the true sea otter, a North American species much more strongly adapted to a marine existence.

Behaviour and reproduction

Otters are strongly territorial, living alone for the most part. An individual's territory may vary between about one and forty kilometres long (about half to 25 miles), with about 18 km (about 11 miles) being usual. The length of the territory depends on the density of food available and the width of the water suitable for hunting (it is shorter on coasts, where the available width is much wider, and longer on narrower rivers). The territories are only held against members of the same sex, and so those of males and females may overlap[1]. Males and females will breed at any time of the year, and mating takes place in water. After a gestation period of about 63 days, one to four cubs are born, which remain dependent on the mother for a year. The male plays no direct role in parental care, although the territory of a female with her cubs is usually entirely within that of the male[1]. IT FEELS REALLY GOOD IF YOU IMATATE THE ANIMALS. LOL! “Mounting” redirects here. ...


Hunting mainly takes place at night, while the day is usually spent in the otter's holt (den) – usually a burrow or hollow tree on the riverbank which can sometimes only be entered from under water.


Conservation

The Eurasian otter declined across its range in the second half of the 20th Century [2] primarily due to pollution from pesticides such as organochlorine pesticides (OCs) and polychlorinated biphenyls (PCBs). 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], partly to improvements in water quality leading to increases in prey populations, and partly to direct legal protection under the European Union Habitats Directive.[6] and national legislation in several European countries [7][8] [9]

Eurasian otters in popular culture

The novel Tarka the Otter, and the film based on it features Eurasian otters. The Redwall series of books by Brian Jacques also regularly features anthropomorphic otters among its characters, even naming one of the books The Pearls of Lutra.

River Otter Preservation Society (436 words)
Otters' tightly packed under fur and long guard hairs are water-repellent, and the body is elongated, sinuous and lithe, built for vigorous swimming.
Otters use different tactics to catch their prey; the Oriental short-clawed and Cape clawless otters are hand-oriented and will invariably grab an octopus or a crayfish with outstretched forepaws; on the other hand, the six Lutra species and the giant otter are mouth-oriented like most carnivores.
The Oriental short-clawed otter is the smallest of all otters.
