Answer;
Statocysts
Explanation;
-The small organs of equilibrium in scyphozoan jellyfishes are called statocysts, and these are borne in more complex sense organs called rhopalium.
The statocyst is a balance sensory receptor present in some aquatic invertebrates, including molluscs, bivalves, cnidarians,ctenophorans, echinoderms, cephalopods and crustaceans. These structures aid in orientation and balance during swimming in medusae and are located around the margin of the bell in Craspedacusta.
