Sea otters search for food using their front paws and highly sensitive noses. Whiskers, in the nose act like fingers; they can move individually and sense where their prey is. Prey can include a multitude of different foods, including sea snails, mussels, crabs, clams, abalone, sea urchins, and many other animals.

Otters are carnivores that are on the top of the food chain. Food chains are forming a food web. Imagine there were no otters. This would influence all the animals that surround it in the food chain. If pollution, such as plastic, enters the water and the otters didn’t eat it, would this still be bad for otters?
