The otter is a carnivore and is an opportunistic feeder, its prey includes- eels, salmonids and crayfish. In spring, otters often eat a lot of frogs. Otters can be difficult to see, but you can tell if they are using an area as they mark their territory by leaving ‘highly scent ’spraints or droppings (marking their territory) and by their five toed foot prints. Otters spend most of their time on land on land but are seldom far from water. They can be found along the whole of the river even in the saltwater of the estuary.
