Starfish; Asteroidea

On reflection a better name is Sea Star; they can be seen most times you’re underwater with the Chaloklum Diving School team.

A giant, multi-legged starfish and eater of corals. They are OK within a balanced ecosystem, but massively destructive when out of control.

They have no arms but the 5 body segments are still apparent. Their mouths are below, and they eat by extruding their stomachs onto their food; charming !

These are more like peoples idea of a starfish or sea star - note that they can have more than 5 arms.
