Northern Sea Star Feeding

Watch this short video to see the sea star’s inverted stomach! The sea star has a feeding method unlike any other; it secures its prey with its tube feet and pries it open—like the shells of bivalve (clams and mussels are favorites!), and then ejects its stomach from its own body, placing it over the digestible parts of the prey. Digestive enzymes produce a soup-like slurry out of the prey, which is then drawn back into the sea star’s digestive glands.
