How often do starfish eat?

Answer 1

Starfish eat clams, mussels, oysters, and other shelled creatures. Sometimes they eat hermit crabs and very rarely tiny ocean bugs or parasites.

AnswerMost sea star (starfish) species are generalist predators, some eating bivalves like mussels, clams, and oysters; or any animal slow enough to be unable to evade the attack (e.g. dying fish). Some species are detritivores, eating decomposed animal and plant material, or organic films attached to substrate. The others may consume coral polyps (the best-known example for this is the infamous Acanthaster planci), sponges or even suspended particles and planktons (sea stars from the Order Brisingida). The process of feeding or capture may or may not be aided by special parts; Pisaster brevispinus or Short-spined Pisaster from the west coast of America may use a set of specialized tube feet capable of extending itself deep into the soft substrata, hauling out the prey (usually clams) from within.

Some species take advantage of the great endurance of their water vascular systems to force open the shells of bivalve mollusks such as clams and mussels, and inject their stomachs into the shells. Once the stomach is inserted inside the shell it digests the mollusk in place. The cardiac stomach is then brought back inside the body, and the partially digested food is moved to the pyloric stomach. Because of this ability to digest food outside of its body, the sea star is able to hunt prey that are much larger than its mouth would otherwise allow including arthropods, and even small fish in addition to mollusks.

Some starfish have been shown to live for several weeks without food under artificial conditions it is believed that they may receive some nutrients from organic material dissolved in seawater.
starfishes eat any animal that is slow so it can not attack
starfish eat corals, kelp,clam, and oyster
Starfish eat mussels, clams, oysters, snails, sponges, sea anemones, coral or other sea stars.
I live by the ocean in BC/while walking my dog we found a star fish in a pool

Just waiting to get caught by an eagle or seagull ( it is a nice size about 10-12"

across and purple in colour) yes! I rescued it I am only two minutes from beach..

It is now resting in a large pool of seawater in my backyard, I would like my grand children to see it when they come out for Easter dinner on Sunday ( I am going to go back and get it some clams when the tide goes out a bit more) and then on Sunday they can take it back to its rightful home and let it go, when the tide is in..

It is such a pretty colour a deep purple, At first my dog thought it was a new play toy !!NoT !!....

I know nothing about these sea creatures,,,So any in put would be good!!

Thanks

Answer 2

Seastars have two stomachs, one of which can be everted out of the animal's mouth. When scavenging on dead things, the star can simply plop out its stomach onto the food. Digestive enzymes go to work on the food, and the resulting slurry is slurped up as the stomach is retracted back into the star's body.
