Sea stars environment?

Question

What rold to sea stars play in their enviornments? How are they specifically adapted to their environment? IF you know a website that gives me this info that would be great!

Answer 1

they are predators on the sea floor, reefs or the rocky intertidal.  they eat shellfish(clams, mussels, oysters).

they have tube feet driven by a hydraulic system that enables them to pull apart shellfish.  their tube feet are also how they move, and how they hold onto rocks when waves come crashing through in the intertidal zone.
