Crown-of-thorns starfish: Community, Taxonomy & Biology

The crown-of-thorns starfish (Acanthaster planci) is a large starfish that preys upon hard coral polyps. The crown-of-thorns starfish, frequently abbreviated to COTS, receives its name from venomous, thornlike spines that cover its upper surface, resembling the biblical crown of thorns. It is one of the largest starfish in the world.
