Are free-swimming (actually, more free-floating; they’re most of all captives of the currents). Comb jellies are named for their unique feature: plates of giant fused cilia, known as combs, which run in eight rows up and down their bodies. The combs act like tiny oars, propelling the comb jelly through the water. Many microscopic organisms, such as bacteria, also use cilia to swim—but comb jellies are the largest known animals to do so.

comb jellies are approximately 1.5 cm long and egg-shaped, with one mouth on one end and anal pores on the other one ( aboral end).

The comb jelly is a stunning, oval-shaped animal that takes its name from the eight rows of tiny, comb-like plates that it uses to propel itself through the water. As it swims, the rows of comb plates diffract the light to produce a shimmering, rainbow effect that keeps our tour guests coming back for more.

Eight rows of brush-like cilia beat against the water, creating a current that brings prey closer to the mouth. Comb jellies have adapted to take in a large amount of food at one time, a tactic that benefits them in the wild, where the food they come across is sparse.
