Otters mainly hunt in water. Sensitive whiskers on their muzzle help them find their prey. Otters can dive for up to eight minutes. Their webbed fingers and toes make them fast swimmers.
Otters live right on the water's edge. They mark their waterside territory, which is up to 20km long, with faeces and scent marks. They build their den on waterside embankments. The entrance is under the water’s surface. Their living quarters are located above the flood line and are complete with ventilation shafts.
