Info
The crown-of-thorns starfish (Acanthaster planci) is a starfish with thorn-like spines sprouting all over its body for protection. These echinoderms grow to a diameter of up to 40 cm across and have 12 to 19 arms extending from their center.
The starfish is a coral reef predator (a corallivore) and preys on the coral polyps by climbing onto them, extruding its stomach over them, and releasing digestive enzymes to then absorb the liquefied tissue.
