About The Cover

The rose sea anemone (Tealia piscivora) exemplifies the beauty of many cnidarians, the simplest animals having a nervous system. Tentacles of the cosmopolitan anemone (Haliplanella luciae) have mechanoreceptors on the surface that tune to the movements of prey identified by chemodetection. See page 1589.
