They don't have mouthparts. They exude their first stomach from their bodies and into the bivalves they commonly eat. This stomach digests the meat inside the shell and then is drawn back into the starfish to be further digested by the secondary stomach. The starfish is a predator of bivalves such as clams and mussels, but is known to scavenge as well.
A starfish's stomach is on the bottom (the soft, fleshy side closest to the ground) Their main source of food is shellfish. In order to get the shellfish out, the starfish squeezes it untill it can't stand the pressure and it opens up. Once the shellfish has been exposed the starfish puts its stomach out of its mouth to digest it.
When a starfish pries open the shell of a clam it often resists Even if the shell opens slightly the starfish gets its meal Why?
Starfish or sea stars are able to turn their stomachs inside out, the extended stomach hangs outside and engulfs food, partially digesting it. Thus it can feed on food larger than its mouth could handle. Eventually, it and the food it is working on, is sucked or pulled back inside their body. The partially digested food then is passed along to a second stomach that completes the digestive process. They can also use their tube…
Not really, mainly starfish prey prefer shelled animals such as oysters and clams. They would not eat starfish because to feed they tend to push open shells using their tube feet and extend their stomach out to engulf and digest food. Starfish have a rough surface and starfish prefer soft tissue as a food.
Starfish extrude their stomach to digest their prey externally then just suck up the results. You can see how this would work for coral. With clams they pull them apart with their sucker feet. It is not strength here but persistence. The clam eventually tires of 'clamming-up' and opens. The Starfish then extrudes its stomach inside of the clam and digests it.
There is no animal that can take its stomach out. It's impossible but there are some animals that can flip their stomachs inside out. One of those animals is the starfish. Another is the great white shark. . Fun Fact: Starfish have two stomachs: the cardiac stomach and the pyloric stomach. The cardiac stomach is a sack like stomach located at the center of the body and may be pushed out of the body to…
