Why do animals live in rivers?

Rivers support the plants and animals that need running water – for animals this means species that depend on constantly high oxygen levels – like stoneflies and many (but not all) mayflies – and filter feeders, like blackflies or net spinning caddis larvae, that depend on moving water to bring their food to them.

How do you find a river otter?

OTTER TRACKS

Toes fan out widely, but webbing rarely prints, except in mud. Running stride is 12–24″ (300–600 mm). Look for tracks on muddy river banks around ponds, streams, lakes, rivers, marshes and beaches near fresh water.
