Starfish are predators, and they’re probably the most important predator in the shallow ecosystem – so the depths where we would dive or swim. They eat basically anything that they can come across, and they have a major role in keeping the numbers of other organisms down, other species down, such as mussels.

[NOTE: Starfish are now referred to as sea stars because the starfish is not a fish, it's an echinoderm.]
