SYMMETRY FLAW. “Many sea anemones (class Anthozoa, order Actinaria) exhibit bilaterality. Like Hydra, the external appearance of a sea anemone is that of a simple cylinder with a single central axis of polarity, the oral-aboral axis. The external radial symmetry is nearly perfect, but it is disrupted by the slit-shaped mouth and external openings on the oral disk.”
