The Eurasian otter (Lutra lutra) is an endangered species for which diet analyses are needed as part of its conservation efforts. Forestry intern Emma shares her knowledge and love of these secretive mammals. The European otter (Lutra lutra), also called the Eurasian otter, inhabits Europe, most of Asia and parts of North Africa.In the British Isles, they were common as recently as the 1950s, but became rare in many areas due to the use of chlorinated hydrocarbon pesticides, habitat loss and water pollution (they remained relatively common in parts of Scotland and Ireland).

J. J. As for their size, the Eurasian otters reach up to 69 centimeters in length, of which about 42 centimeters correspond to their tail. Prey preference and seasonal variation in the diet of the Eurasian otter, Lutra lutra (Linnaeus, 1758), were examined by the analysis of 789 spraint samples collected along a 10‐km section of a small lowland salmonid river in Serbia, with a trout farm situated in its lower part, from June 2009 to March 2012.

An otters diet mainly consists of fish, however, it can also include birds, insects, frogs, crustaceans and small mammals. peer-00633606, version 1 - 19 Oct 2011. Eurasian otters feed on fishes, amphibians, crabs, birds, and insects [ 3, 4 ], and are at risk of intake of polluted diets, which may lead to a further decline in their population [ 5 ].

We investigated how the foraging strategy of the Eurasian otter Lutra lutra (L.) has responded to this change in a Mediterranean catchment of the Iberian Peninsula, over a 30-year time span (1980 vs. 2010).

They develop slowly and the eyes will open in five weeks.

Keywords Eurasian otter.Diet.Coastal.Marine. Knowledge of the effect of habitat type and region on diet and feeding behaviours of a species facilitates a better understanding of factors impacting populations, which contributes to effective conservation management. In many areas of Europe and Asia, otters remain a species of conservation concern following widespread population declines during the 20th century (Ruiz-Olmo et al. The Eurasian otter (Lutra lutra L.) is a top predator in aquatic systems and plays an important role in ecosystem functioning.However, it has undergone dramatic declines throughout Europe as a result of environmental degradation.
