What do sea otters eat? Sea otters eat sea urchins and other mollusks and crustaceans. This includes clams, snails, sea stars, sea urchins, squid, and octopuses. How would you like to eat sea otter food? They can hold their breath for up to five minutes, allowing a long dive to the ocean floor to hunt for food. They use rocks as tools to crack open prey.
