Starfishes, sea urchins, and sea lilies all belong to the phylum echinodermata. Like some other invertebrates, echinoderms live their lives entirely in water. They can be recognized by their spiny skin and by their five part radial symmetry.
Yes, all echinoderms have radial symmetry.
No, echinoderms do not have bilateral symmetry. They have radial symmetry, which means their body parts are arranged around a central axis.
According to animal classification into bilateria and radiata (ACCORDING TO SYMMETRY)the echinoderms and molluscs are bilaterally symmertrical.
All echinoderms have radial symmetry
yeah yeah
No. Most have radial symmetry. No. Most have radial symmetry.

Echinoderms are thought to have evolved from bilaterally symmetrical ancestors because their larval forms exhibit bilateral symmetry. Over time, echinoderms undergo a process called pentaradial symmetry, where they develop a five-point radial symmetry characteristic of adult echinoderms. This suggests a modification from bilateral to radial symmetry during evolution.
Echinoderms are a phylum with usually 5 fold symmetry, spines and calcium carbonate plates.

Radial! :D
Cnidarians are true radially symmetrical animals. They include jellyfish. Echinoderms (like starfish) also display radial symmetry. It is important to note that the larvae of echinoderms are bilaterally symmetrical and that Echinoderms evolved from a bilaterally symmetrical group.
