They mainly prey on reef coral polyps and brittle sea stars. But when they are short on food, they can survive on energy reserves.
They eat clams, muscles, and oysters by inserting their stomach in to the shells and digest their food on the spot. Sea stars also like plankton
The sea star's predators are birds, otters, and humans. This is according to http://library.thinkquest.org/J001418/star.html. Sea Stars (like Solaster dawsoni) also prey on other species of sea stars (like Pycnopodia helianthoides).
Sea urchins feed mainly on algae, but can also feed on a wide range of invertebrates such as mussels, sponges, brittle stars and crinoids. On the oral surface of the sea urchin is a centrally located mouth made up of five united calcium carbonate teeth or jaws, with a fleshy tongue-like structure within. The entire chewing organ is known as Aristotle's lantern, which name comes from Aristotle's accurate description in his History of Animals.

Sea Stars do not even have any blood at all in their body. They also do not have a brain either. ! :) Adios Amigos!
Algae are in a symbiotic relationship with coral.Parrotfish, butterfly fish, angelfish, sea slugs, snails, worms and the crown-of-thorns starfish all eat coral.
ummm they live in the ocean
sea stars eat clams and oysters
There is at least one venomous species called the crown of thorns and has poison spikes. Search images to see one.
A starfish called Crown of Thorns starfish.The Crown-of-Thorns Starfish Acanthaster planci, commonly known as the crown-of-thorns starfish, is a large multi-armed starfish (or seastar) that usually preys upon hard, or stony, coral polyps (Scleractinia). It is a coral reef predator which preys on coral polyps by climbing onto them, extruding its stomach over them, and releasing digestive enzymes to absorb the liquified tissue. An individual adult of this species can eat up to six square metres of living reef in a single year.
Many of the fish (butterfly's, angels, wrasse, and many others) eat the coral. There are also numerous invertibrates that eat the coral, a few examples are the crown of thorns starfish, and many many kinds of nudibranch(sea slugs).
Yes. Sea stars are carnivores that eat can eat other sea stars and shrimp and other crustations like crabs. Over a long period of time sea stars move across the ocean floor. Giant sea stars will sometimes specifically prey on other, smaller sea stars. they eat poop
One animal that eats coral is the parrotfish. It has a very hard beak-like mouth and bites off bits of coral, eating the live coral animals and eventually excreting the hard parts as sand. Another is the Crown of Thorns Sea Star, which extrudes it's stomach over the coral to digest it. In groups they can decimate an outcrop of coral. The Crown of Thorns is covered with venomous spines which exude a neurotoxin.
One of the biggest coral eaters would be the crown-of-thorns starfish. Other creatures would include angelfish, scalus parrotfish and filefish.
they eat
The Crown of Thorns starfish is the biggest natural threat to the Great Barrier Reef.
Sea fish eat everything that a sea star would eat. They call them sea stars because thats a more scienctific name. Sea stars and sea fish are the same thing. Answer: clams and musels
