Sea otters are carnivorous. They will eat nearly any seafood they can find in their kelp forest foraging grounds. Their diet consists of marine invertebrate herbivores and filter feeders such as mussels, sea urchins (Strongylocentrotus sp.), snails, and abalone. Otters also are known to eat crabs, octopus, squid, sea stars, and fish. Individuals tend to be specialized in their choice of prey: one otter may consume only urchins and crabs while another will eat mostly fish, all depending on the abilities of the individual otter and what is available in the area. Otters need to consume 20-25% of their body weight each day. They obtain most of their water from prey but will drink seawater to satisfy thirst also.
