Most starfish eat ____
A
sponges
B
cnidarians
C
worms
D
mollusks
Explanation: 

Detailed explanation-1: -Their diets include clams and oysters, arthropods, small fish and gastropod molluscs.

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: -What Eats Them. Predators (animals that eat them) include crabs, lobsters, bottom dwelling fish, other sea stars, and seagulls. Sometimes a predator will grab onto a sea star’s arm and the sea star can detach or let go of it to get away. But don’t worry, they can regrow their arms!

Detailed explanation-4: -They usually feed on coral, sponges, clams, oysters, sand dollars, and mussels because these animals also attach themselves to rocks and move slowly, so they’re nearby. Some starfish will also eat other animals, such as fish, if they are injured and unable to move away in time.
