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. Sea stars are mostly carnivorous and prey on mollusks—including clams, mussels and oysters—which they pry open with their suction-cupped feet.
Do starfish eat giant clams?
It may seem like the sheer size of this clam would keep all threats away. But this mollusk does have some predators. Reef fish, eels, and starfish eat the meat of the clam. Humans also harvest these clams to eat their meat.
How do sea stars eat shellfish?
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.
Do brittle starfish eat clams?
Well-Known Member. Most starfish do not eat clams. Some do and are predatory, others do not and are scavengers or detritivores. The starfish in question are small, probably micro brittle stars or asterina stars which are scavengers and are not clam predators.
What is the relationship between starfish and clams?
The sea star climbs onto a clam and using its tube feet, it attaches to the clam’s shells and pulls on the shells until the clam weakens and opens the shells. When there is an opening, the sea star everts its clear, baglike stomach into the space and onto the clam’s body.
Why is Seastar more accurate than starfish?
Why is it more accurate to say “sea star” than “starfish”? Sea stars are bottom-dwelling invertebrates that are not fish at all; they have neither scales nor a backbone. Therefore, sea star is more appropriate for the organism.
How long can a starfish pull on a clam before getting it open?
A closed clam is almost impossible to open, but a hungry sea star can do it. It crawls onto the clam shell and attaches itself, using its hundreds of tiny, tube- shaped feet that work like suction cups. And then it pulls. A sea star can pull for hours, even for days.
How long does it take a starfish to eat a clam?
What are clams predators?

How do you feed a brittle starfish?
Food : They should scavenge the tank floor and rock surfaces at night. You can try supplemental feedings by placing small pieces of fresh uncooked seafood near them. They may come out when they sense that fish food hits the water.

How do sea stars protect themselves from predators?
A sea star uses its strong arms to pry open a mussel shell. It everts its stomach to digest the flesh outside its body. Predator-prey interactions: how sea stars prey on mussels. Through natural selection predators and their prey adapt ways of hunting and defense. Mussels close-up tightly but strong sea stars can still pry them open.
How do echinoderms eat mussels?
