2021-03-13 · Comb jellies are the largest known animals to use cilia for motility and can range in size from around 1 mm (0.4 inches) to 1.5 m (4 ft 11 in). Comb jellies are radially symmetrical The phylum Cnidaria includes other jellyfish , corals, and sea anemones, all of which are radially symmetrical. Ctenophores, commonly known as the Comb Jellies have biradial symmetry. Regarding the number of germ layers, Ctenophores are a little controversial. Traditionally, these animals are considered to be diploblastic.
dorsal The two halves of a radially symmetrical animal may be described as the side with a mouth (“oral side”) and the side without a mouth (“aboral side”). This form of symmetry marks the body plans of animals in the phyla Ctenophora (comb jellies) and Cnidaria (corals, sea anemones, and other jellies). The fundamental domain is a half-plane through the axis, and a radial half-line, respectively.
Ctenophores, commonly known as the Comb Jellies have biradial symmetry. Regarding the number of germ layers, Ctenophores are a little controversial.

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. Each single comb within a row is made up of several thousand cilia, and each row may have dozens of combs, so an individual ctenophore is endowed with many thousands of cilia.
