What is the starfish that eats coral?
crown-of-thorns starfish
The crown-of-thorns starfish (Acanthaster planci or COTS) eats coral.
What do starfish do in coral reef?
Normally, the starfish contribute to the reef’s diversity by eating faster-growing coral species, which allow for slower-growing species to thrive. But at outbreak levels, the starfish are able to eat coral — a polyp that builds the limestone reefs on which they communally live — faster than the coral can reproduce.
Are starfishes poisonous?
The answer is no, starfish are not poisonous at all and their spikes can’t hurt you unless it pierces your skin – or if the spike has a venomous substance on them which only happens in some species of sea stars like urchins. Experts often tell people not to pick up starfish, especially if they’re on the shore.

What is the largest coral reef in the world?
the Great Barrier Reef
Stretching for 1,429 miles over an area of approximately 133,000 square miles , the Great Barrier Reef is the largest coral reef system in the world. The reef is located off the coast of Queensland, Australia, in the Coral Sea.
Why can an atoll island sink?
If corals and reef sand isn’t produced fast enough to keep up with sinking islands or rising seas, the atolls will eventually drown – just as has happened in the most northwest of the Hawaiian Islands. However, if water temperatures are too warm, corals bleach and skeletal growth is inhibited.
Do starfish eat coral reef?
The crown-of-thorns starfish (Acanthaster planci or COTS) eats coral. It prefers fast growing hard corals such as plate and staghorn corals but when these aren’t available it will eat all species. However, the consequence of a large outbreak is well understood – the decimation of the coral reefs in its path.
Are starfish Reef Safe?

Why do fishermen hate starfish?
Starfish off of Cape Cod are apparently reproducing like crazy and devouring all of the shellfish—mussels, oysters, scallops—which are prized by fishermen. They actually eat their prey by shooting their stomach out of their mouth, which is “disgusting” to even the most hardy fishermen.
Is it illegal to take starfish from the ocean?
It is illegal in California to take sea stars (starfish) off nearshore rocks if they are between the mean high tide line and 1,000 feet seaward of the mean low tide line? Outside of this zone you may take 35 sea stars and you’ll need a valid fishing license.
What type of starfish eats coral?
In recent years, over 50% of the Great Barrier Reef was destroyed by crown-of-thorns starfish (COTS), large marine invertebrates covered in long, poisonous spines. These spiky and colorful starfish are known to eat coral polyps, which reside on coral reefs.
What do Crown of thorns starfish eat?
Crown-of-thorns starfish usually eat the polyps of hard, relatively fast-growing stony corals, such as staghorn corals. If food is scarce, they will eat other coral species. They feed by extruding their stomach out of their bodies and onto the coral reef and then using enzymes to digest the coral polyps.
What are facts about the Crown of thorns starfish?
