radial symmetry
A starfish has radial symmetry
Starfish tend to have pentamerous radial symmetry. In other words, the typical starfish has five lines of symmetry throughout their body. Some species have more lines because they have more arms.
Most Echinoderms have radial symmetry. Sea Urchins, Starfish, Sand Dollars, etc.
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)
