Ctenophores , commonly known as the Comb Jellies have biradial symmetry . 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 have a wide variety of body shapes, from small, roughly spherical species of less than a centimeter in diameter, to flattened, ribbon-shaped forms that reach lengths of up to two meters. They are of biradially symmetrical and acoelomate.

'comb' and φέρω, pherō, 'to carry'; commonly known as comb jellies) comprise a phylum of invertebrate animals that live in marine waters worldwide. 2007-01-29 · Comb jellies are the largest of all animals that utilize the beating of cilia for locomotion. It doesn't stop there - with lengths up to 2 mm, ctenophore cilia are the longest of any known.
