Talk:Crown-of-thorns starfish

Crown-of-thorns starfish (Acanthaster planci) naturally occur on coral reefs.

They are corallivores (i.e., they eat coral polyps). Covered in long poisonous spines, they range in color from purplish blue to reddish-gray to green. They are generally 25-35 cm in diameter, although can be as large as 80 cm.

Crown-of-thorns starfish (COTS) are found throughout the Indo-Pacific region, occurring from the Red Sea and coast of East Africa, across the Pacific and Indian Oceans, to the west coast of Central America.

Predators of COTS include the giant triton snail, the stars and stripes pufferfish (Arothron hispidus), the titan triggerfish (Balistoides viridescens), and the humphead maori wrasse (Cheilinus undulates).
