seastar
Five-armed ocean dweller
A seastar is an echinoderm with a central disc and radiating arms, more commonly called a starfish.
The term seastar is preferred in scientific contexts because the creature is not actually a fish.
Most have five arms, though some species have many more, and they can regenerate lost limbs.
Seastars are found in oceans worldwide, from shallow tide pools to deep sea floors, where they feed primarily on mollusks and other invertebrates.
