How It Works

33 Starfish eject their own stomachs to eat

-

Travelling at 15 centimetre­s per minute starfish are some of the slowest moving creatures in the ocean. So how do they munch down a meal along the way? Without any razor-sharp teeth or claws to grasp their food, starfish have evolved a unique way to capture their prey that still makes them a deadly predator. Striking fear into the hearts of corals, clams and oysters alike, starfish deploy their own stomach to engulf and digest their food. Extending out through their mouths, their stomach absorbs their prey while a digestive enzyme begins to break down the food. Now a seafood soup, the liquidised prey and the stomach are then retracted back via the mouth, and digestion continues in their ten digestive glands.
