How do starfish eat?

Starfish

A starfish’s mouth, underneath its flat body, leads directly into a large, bag-like stomach. The starfish can push its stomach out through its mouth.  Starfish like to eat clams and oysters.  Encircling a clam with its powerful arms, the starfish attaches its sucker-like tube feet to the clam’s shell.

With ever-increasing force, it pulls the two halves of the shell apart.  Then, the starfish pushes out its stomach and digests the food.  When the starfish has completed its meal, it pulls back its stomach, and leaves only an empty clam shell behind.–Dick Rogers

What is a starfish?

Starfish

A starfish is a star-shaped animal that lives on the bottom of the sea in bays and shallow water.  Starfish eat clams and other shellfish by pulling the shells apart and pushing their stomach into the shells to digest the food.

Starfish have a peculiar way of eating.  The common starfish feeds mostly on shellfish, it especially likes to eat clams, oysters, and mussels.

To open a clam shell, the starfish wraps its arms around it.  Under each arm are rows of tube like feet that stick to the shell like suction cups.  The starfish then pulls the two section of the clam’s shell assist with its powerful arms.

A starfish’s mouth is under its body.  As soon as a starfish has pulled open the clam, it opens its mouth, turns it stomach inside out and pushes it inside the clam’s shell and digests the clam’s soft body.

Once the meat is finished, the starfish pulls back its stomach, leaving only an empty clam shell behind.  Most starfish have five arms, but some have seven arms or more.  If a starfish loose an arm, it can grow another. – Dick Rogers
