Brittle stars have several natural predators, including fish, crabs, sea birds, and some marine mammals. They are also vulnerable to certain species of larger sea stars that may feed on them. Additionally, brittle stars may face competition for food and resources from other bottom-dwelling marine organisms.
Some harmful echinoderms include crown-of-thorns starfish, which can devastate coral reefs by feeding on coral polyps; the flower urchin, which can overgraze algae and disrupt marine ecosystems; and sea cucumbers, which can damage habitats by overconsuming sediments.
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).
Some animals that have thorns include the porcupine, certain species of sea urchins, and spiny anteaters. These thorns are often used for defense against predators or to help with camouflage.
Sea stars feed on different types of prey, such as bivalve mollusks, snails, and barnacles. One of their favorite foods is clam species. They use their tube feet to pry open the clam's shell and then push their stomach out to digest the soft tissues inside.
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).
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.
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 of the biggest coral eaters would be the crown-of-thorns starfish. Other creatures would include angelfish, scalus parrotfish and filefish.
The Crown of Thorns starfish is the biggest natural threat to the Great Barrier Reef.
they eat
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
