, adult males are typically 50% larger than females. The Eurasian Otter has a long body and a conical tail. The short, dense pelage is brown to almost black throughout, with slightly paler undersides. The legs are short; the feet are fully webbed and have well-developed claws. There are two to three pairs of mammae. The cranium is large and flat. Dental formula: 13/3, C1/1,P 4/3, M 1/2 = 36.

The diet is mainly fish, frogs, and aquatic invertebrates (including crustaceans and crabs). Birds and small mammals (such as rodents and lagomorphs) may be consumed on occasion. In general, the mean proportion offish declines from 94% on seashores, to 71% on lakes and fish ponds, to 64% on rivers and streams. On inland waters, the abundance of crayfish is an essential food item. In

, over 50% of spraints were composed of sticklebacks (Gasterosteus aculeatus), salmonids and cyprinids, with Sticklebacks constituting the most frequently occurring prey category. The frequency of occurrence of eels (

|
||
<collectingCountry box="[1184,1276,1281,1314]" name="Poland" pageId="26" pageNumber="645">Poland</collectingCountry>

,fish constitutes 51% of the food biomass consumed in spring-summer and 40% in autumnwinter, with perch (Perca fluviatilis), pike (Esox lucius), and roach (Rutilus rutilus) being captured most frequently. Amphibians (mainly Rana temporaria) make up 34% of the food biomass in spring-summer and 58% in autumn-winter. The cold season diet depends on river size. On small rivers with forested valleys, Eurasian Otters feed nearly exclusively on amphibians (72-90% of food biomass). As the size of the river increases, and riverside habitat becomes more open (sedge and reed marshes instead of forests), Eurasian Otters shift to catching predominantly fish (up to 76%). In southern
|
||
<collectingCountry box="[1242,1342,1595,1628]" name="Poland" pageId="26" pageNumber="645">Poland</collectingCountry>
|
||
, the main component of the diet is fish (47-9%, including brown trout Salmo trutta and rainbow trout Oncorhynchus mykiss). Other important food items are 21-4% frogs (

|
||
<collectingCountry box="[576,634,1753,1786]" name="Italy" pageId="26" pageNumber="645">Italy</collectingCountry>
|
||
, spraint analysis revealed that fish represented the dominant food (57-3% mean volume), followed by amphibians (18:9%) and crayfish (15-6%). Seasonal variations in fish consumption were related to changes in fish activity and to environmental conditions; the importance of fish decreased in winter, when flooding increased water speeds and turbidity, and thus reduced the hunting efficiency of the otters. Hibernating amphibians represented a primary alternative resource. Insects and reptiles were eaten more frequently in summer, while birds predominated during their breeding season. In

, the primary food is fish (89-8% for riverine and 87-5% for backwater habitats); Eurasian Otters living in riverine habitats, compared to backwaters, consume more birds (3-9% and 0-7%, respectively), less mammals (0-5% and 0-9%, respectively), less reptiles and amphibians (5-6% and 10-2%, respectively) and less invertebrates (0-1% and 0-6%, respectively); most fish eaten are small-sized (below

Eurasian Otters are excellent swimmers and divers. They are usually found no more than a few hundred meters from water, but they may travel several kilometers overland between wetlands. They swim using movements of the hindlegs and tail; usually dives last one or two minutes,five at the most. When traveling on the ground, snow, or ice they may use a combination of running and sliding. Males typically are solitary, whereas females may occur in groups, either with their own young or with unrelated, reproductive females and their young. The straight-line length of a home range may reach an average of

Females are polyestrous, with the cycle lasting four to six weeks; estrus lasts about two weeks. Mating typically occurs in late winter or early spring. The gestation period is 60-63 days and births peak in April or May. The main entrance of bank burrows may open underwater and then slope upward into the bank to a nest chamber that is above the high-water level. Litter size is one to five, usually two to three. The young are born blind and weigh about
