they are called rays
radial symmetry
A starfish has radial symmetry
ctenophorains(jellysfish) are spherical in shape much like a ball hence show radial symmetry. echinoderms(starfish) generally are flatter and have 5 arms hence are called pentaradial symmetry (can be cut in only 5 directions)
Most Echinoderms have radial symmetry. Sea Urchins, Starfish, Sand Dollars, etc.

Starfish
Yes, they do.
A radial body plan. Starfish and jellies are example of organisms with a radial morphology.
Box starfish has pentaradial symmetry.
Well, honey, a starfish is like the Picasso of the ocean - it's all about that funky radial symmetry. They may look like they partied too hard and lost a few limbs, but those five arms are arranged in a symmetrical pattern around a central point. So, yes, a starfish has symmetry, just not the kind you'd find in a boring ol' square.
Starfish belong to the species of phylum Echinodermata. Starfish are found in the oceans around the world with a large population in the Pacific and Indian oceans.
The possessive form is the 'starfish's arms'.
