Radial symmetry
pentaradial
The symmetry of the larvae of echinodermata is bilateral.
Deuterostomes that show radial symmetry in their adult form called phylum Echinodermata. Phylum Echinodermata are things like sea stars, sea urchins and sea cucumbers.

The phylum Echinodermata has radial symmetry as adults. These organisms include sea stars, sea urchins, and sand dollars, among others. Radial symmetry means that body parts are arranged around a central axis, like the spokes of a wheel.
The most prominent animal phyla with radial symmetry are the Echinodermata (starfish and sea urchins) and the Cnidaria (jellyfish and corals).
The body of the Phylum Echinodermata is divided into 5 equal sections whereas the body of the Phylum Chordata is divided bilaterally (2 sections).
Radial symmetry
Cnidaria (Hydra, jellyfish, sea anemones, corals, etc.), generally have radial symmetry, although not all sea anemones or corals do. Echinodermata (sea stars, sea urchins, crinoids, sea cucumbers, etc.) are radially symmetrical as adults, but not as larvae.
Yes, echinoderms are multicellular organisms. They are characterized by radial symmetry and a water vascular system that helps in locomotion and feeding.
No. Most have radial symmetry. No. Most have radial symmetry.
