dipleurula larva A type of echinoderm (Echinodermata) larva that incorporates features common to all types of echinoderm larvae and is hypothetically the ancestral type. It has bilateral symmetry, three coelomic sacs (see COELOM), longitudinal ciliated bands for locomotion, and adoral ciliated bands for feeding. Some authorities claim similarities between this and the tornaria larva indicate affinities between Echinodermata and Chordata.
