Predators & defenses : Many different types of animals prey on adult sea urchins, including birds, sea otters, fishes, crabs, lobsters, octopuses, and sea stars. Eggs and larvae of sea urchins are eaten by many types of carnivorous zooplankters and by suspension-feeding invertebrates including hydroids, sea anemones, and mussels, just to name a few.
When a sea star strives to get near an urchin, the urchin moves its spines aside and lets the sea star's arm get really close. Then the pincers chomp on the sea star's tube feet. The sea star immediately backs off. However, purple sea urchins' pincers can't defend against sunflower stars. If a sunflower star approaches, an urchin waves its spines and pincers and retreats. If the urchin doesn't move away fast enough, the sunflower star swallows the urchin whole.
