Echinoderms are a phylum with usually 5 fold symmetry, spines and calcium carbonate plates.
No, echinoderms do not have bilateral symmetry. They have radial symmetry, which means their body parts are arranged around a central axis.
water vascular system
Among the listed animals, echinoderms, such as starfish, do not display segmentation. Segmentation refers to the division of the body into repetitive segments, which is seen in animals like annelids (earthworms) and arthropods (insects and crustaceans). Echinoderms have a unique body plan characterized by radial symmetry and a water vascular system, rather than the segmented structure found in other groups.
