Coral reefs are busy places.
They’re home to lots of weird and wonderful animals – like sea stars!
Most sea stars have five arms, but not this one.
Meet the sunflower sea star.

Crazy Skill:
Regeneration
This sped-up footage shows a sunflower sea star on the move!
These sea stars have around 20 arms, covered in thousands of sticky tube feet.
They use these tube feet to move around and to catch food.
Sunflower sea stars have tough, spiny skin, to help protect them from predators, but that doesn’t always stop them from being attacked.
A king crab tears off this one’s arm!
Luckily, it has the amazing ability to regenerate its arm! In a few weeks, it will have all its arms again – phew!
