Crown-of-thorns starfish skeleton. Coloured X-ray of the crown-of-thorns starfish (Acanthaster planci). This starfish lives on coral reefs in the Indo-Pacific region. It has between 12 and 19 arms, covered in long spines on the upper surface. These spines contain glands that release poison into the skin of an attacker. Its mouth is on its lower side and it feeds on the polyps that build coral. The increase in numbers of this starfish poses a serious threat to coral reefs.
