Lutra lutra forage in water and nest on land. They inhabit rivers, lakes, streams, freshwater and peat swamp forests, ricefields, ocean shores, fjords, caves, and terrestrial habitats adjacent to waterways. Covered dens and dry resting sites are found in earth tunnnels, tree roots, boulder piles, shrubs, and banks. In its territory of 1 to 4 miles, each river otter has fixed locations for getting into and out of the water, rolling, sunbathing, and sliding on "otter stairways". (Grzimek 1990, Sivasothi 1994)
