Eurasian river otters can be found in Europe, Asia and Northern Africa. They even live at the sea shore. Otters are solitary animals doing nocturnal migrations, which may lead lots of kilometres through areas of solid ground. Their physiques are well adapted to life and hunt in water.
Females are a little smaller than males.
River otters hunt fish but also all other kinds of small animals living in or near the water. The amount of fish they eat varies through the seasons. Since there is no certain mating season in River otters, young are born throughout the year. Pregnancy lasts for 9 weeks. A litter consists of 1 - 3 pups, which stay with their mother for about one year.
