The crown-of-thorns is a venomous starfish that lives in the Great Barrier Reef. Growing up to massive lengths of 80 centimetres and having a body entirely covered in toxic spikes, the starfish is almost indestructible and is a vicious predator. They eat coral, the building blocks of the Great Barrier Reef. It’s said that one adult starfish can eat up to ten square metres of coral every year.
