Description: Describes the characteristics of the echinoderm body plan and shows how it is adapted for locomotion, respiration, digestion, and reproduction. Examples of the five classes of echinoderms are shown., Defines echinoderms and examines the body plan of the sea star. Shows their spines and hydraulic system. Illustrates the five classes of echinoderms through live-action and close-up photography. Reveals how reproduction takes place using microcinematography and animated drawings of classic laboratory experiments.
