Eurasian Otter
Lutra lutraAlso known as European Otter, Common Otter, Old World Otter, Eurasian River Otter
Eurasian otters are sleek, semiaquatic predators equipped with dense, water-repellent fur and webbed feet that make them incredibly agile swimmers. They are highly territorial, patrolling extensive river systems, lakes, and coastal areas where they scent-mark their boundaries using sweet-smelling droppings called spraint. While they primarily hunt fish, their opportunistic diet also includes amphibians, crustaceans, and waterfowl.

- Very high
- Why interaction risk is low
- Capable of delivering a painful bite if cornered; observe quietly from a safe distance.
- What to notice
- Look for a long, streamlined body with a broad, flattened head and a thick, tapered tail.
- Support conservation
- Avoid disturbing potential holts or resting sites, and keep dogs on leashes near sensitive riverbanks.
Responsible observation
- Look for spraints: Search flat rocks, fallen logs, and under bridges for sweet-smelling, fishy droppings used to mark territory.
- Watch the water: Scan calm river surfaces at dawn or dusk for a V-shaped wake and a small, flat-headed profile.
- Listen for whistles: Listen closely near riverbanks for high-pitched whistles, which mothers and cubs use to communicate.
