seastars
Five-armed ocean dwellers
Seastars is an alternative name for starfish—marine animals with radial symmetry, typically five arms, and the ability to regenerate lost limbs.
The term avoids the misnomer in *starfish*, since these creatures aren't fish at all.
Scientists and aquariums increasingly prefer *sea star* as the more accurate designation.
