GENERAL HISTOLOGY

Detailed explanation-1: -It pushes one of its two stomachs inside out through its mouth and into the clam’s shell . Inside the shell, this stomach swallows the clam’s soft body. Because sea stars have no teeth, they cannot chew. They must make their food soupy before they can eat it.

Detailed explanation-2: -The starfish forces open the shell with suction disks on the underside of its body, and then inserts its stomach membranes through its mouth into the opening of the shell. Digestive juices break down the shellfish’s body, which is then absorbed into the starfish’s stomach.

Detailed explanation-3: -Did you know that sea stars have a peculiar way of eating? They digest prey outside of their bodies by extruding their stomach out through their mouth and enveloping their meal. Once the food is digested, their stomach is drawn back into their body.

Detailed explanation-4: -Starfish are mostly carnivores and scavengers. Other species are omnivores. These organisms feed on slow-moving creatures like bivalves, gastropods, polychaetes, and barnacles. Other starfish feed on planktons, organic detritus, and fish.

Detailed explanation-5: -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.
