In New Leaf

In New Leaf, an information board in the aquarium will list information about this creature.

"These star-shaped creatures have hundreds of tiny feet attached to their mobile arms. This allows them to slowly walk and open shellfish for food, making them effective predators. If an arm gets caught and ripped off by another predator, the sea star's arm will just grow back. Some sea stars eat by extending their stomachs out of their mouths to trap and then digest prey."
