starfish

Five-armed crawler

A starfish is a sea creature with a central disk and radiating arms, typically five, giving it a star shape.

Also called sea star.

Starfish move slowly across ocean floors, feed on mollusks, and can regenerate lost limbs.

The word sometimes describes a person lying spread-eagled: She starfished across the bed.
