Jellyfish Sensory Organs ( Aurelia Tentaculocysts )

Despite their common name, jellyfish are not fish at all, but are rather cnidarians that have a medusoid, or bell-like, body shape. The jelly, or mesoglea , in scyphozoan jellyfish is thick and surprisingly firm to the touch considering the substance is composed of approximately 90 percent water.
