Habitat
Eurasian otters primarily inhabit freshwater environments such as rivers, lakes, and streams, often with abundant vegetation and bankside cover for shelter. They are found across Europe, Asia, and parts of North Africa, preferring clean, unpolluted waters and avoiding heavily urbanized areas. These otters are adaptable but thrive in areas with access to both water and nearby terrestrial habitats for resting.
Diet
Eurasian otters mainly eat fish such as perch and eels, supplemented by amphibians like frogs, crustaceans, and occasionally small birds or mammals. They hunt primarily at dawn and dusk using their sensitive whiskers to detect prey in murky waters. Feeding behavior involves diving and chasing, with otters consuming about 1 kg of food daily.
Behavior
Eurasian otters are mostly solitary and territorial, marking their ranges with spraint (feces) to communicate with others. They are primarily nocturnal or crepuscular, spending much of their time swimming and foraging, while resting in dens called holts during the day. Notable behaviors include playful sliding on riverbanks and agile hunting techniques in water.
Conservation Status
The IUCN status of the Eurasian otter is Near Threatened, with populations stable or increasing in some areas but declining due to habitat loss and pollution. Major threats include water contamination from pesticides and urban development, which fragment their habitats.
