Sea Otters eat urchins, abalones, mussels, clams, crabs, snails, and many more marine species. Sea Otters eat approximately 25% of their weight in food in each day in order to support their high metabolism. Sea otters usually feed in small groups and all the hunting occurs on the seafloor. They use their sensitive whiskers to locate the small sea creatures and their small forepaws to capture the prey and then rub, roll, and twist It apart. Sea otters usually eat 3 to 4 times a day. After breaking open their food with rocks many otters then wash their prey by holding it on their body and turning around in the water
