The scourge of the sea – crown-of-thorns starfish – is reportedly scavenging coral off the coast of Krabi’s Phi Phi Island.

Upon first glance, the crown-of-thorns starfish looks a lot like an enemy creature you'd find in a nature-based video game. Long spikes cover its body, which can reach 2 1/2 feet in diameter. It's somewhat reminiscent of a land mine, if a land mine had 14 to 21 movable arms.
