No. Most have radial symmetry. No. Most have radial symmetry.
How are echinoderms radial symmetry different from a jellyfish?
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)
Adult echinodermata have symmetry?
Radial symmetry
What does a starfish illustrate?

Adult echinodermata have what kind of symmetry?

Type of symmetry exhibited by echinoderm larvae?

Do box starfish have bilateral or radial symmetry?

Why is a starfish's symmetry different from a jellyfish's?

Is radial symmetry common in echinoderms?
Yes, all echinoderms have radial symmetry.
Do echidnodermata have 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
How many arms does a starfish usally have?
5, it displays "pentaradial" symmetry.
Five example of animals that exhibit pentaradial symmetry?
butterfly,rat,tiger,bird,dog
