WebMar 2, 2024 · Cnidarians are radially symmetrical (i.e., similar parts are arranged symmetrically around a central axis). They lack cephalization (concentration of sensory organs in a head), their bodies have two cell layers rather than the three of so-called higher animals, and the saclike coelenteron has one opening (the mouth). WebCephalization is an evolutionary phenomenon in which the mouth, sense organs, and nerve ganglia are concentrated at the front end of an animal over many generations, resulting in a head region. This is linked to movement and bilateral symmetry, which means the animal has a distinct head end. Is it true that all animals have cephalization?
