No. Most have radial symmetry. No. Most have 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)
Radial symmetry
pentaradial symmetry ;)
pentaradial
the same type as blue footed underwater donkeys.
Box starfish has pentaradial symmetry.
starfish = pentaradial
Yes, all echinoderms have radial symmetry.
they have what we call "pentaradial" symmetry, but certain species, such as the sand dollar, and the sea cucumber, have a secondary body symmetry, which is a bilateral symmetry
5, it displays "pentaradial" symmetry.
