Many jellyfish are capable of avoiding potentially damaging stimuli, but their responses are generally slow and highly localized (Mackie, 1984). less than bell diameter). The directional flexions are conducted by FMRFamide immunoreactive nerves, the lip flaring by an excitable epithelium lining the radial canals. Many of the prolate jellyfish utilize an ambush-style feeding strategy, relaxing their tentacles during extended periods of non-swimming to produce a passive net for ensnaring prey (Colin and Costello, 2002). 2000 Jun;203(Pt 12):1797-807. Watch for jellyfish.

In addition to swimming, their jellyfish-like robot can selectively transport beads of different sizes to mimic food catching, burrow into fine beads to escape from ‘predators’ or target objects, mix different fluids, and generate a chemical path in its wake. This dichotomy was first demonstrated by G.J. Central circuitry in the jellyfish Aglantha digitale. Distinguished by eight bands of cilia. In cnidarian life cycles with medusoid stages, free-swimming jellyfish represent dispersal and reproductive forms that are capable of directional swimming and that can have elaborate feeding, protective and escape responses.
