WhyReef - Fun Facts
The crown-of-thorns sea star is one of the largest sea stars on the reef! It is located in especially large numbers in Australia’s Great Barrier Reef, as well as in reefs in the Red Sea and the Pacific and Indian oceans. It can grow to almost 16 inches (40cm) across, and has 12 – 19 arms, not the standard 5 arms that most starfish have. The crown-of-thorns sea star is covered with spiky spines that protect its body from predators, but even if someone did bite off one of its arms, it can re-grow it! This is something that all sea stars can do.
