[kohm]
comb jelly, common name for transparent organisms of the phylum Ctenophora.
or comb jelly

Any of nearly 90 species (phylum Ctenophora) of usually colourless marine invertebrates that have a series of vertical ciliary combs over their bodies. Ctenophores are sometimes mistaken for jellyfish. The body is round or spherical, with tentacles to capture food, and the combs beat to provide locomotion. Most species are small (not much greater than 0.1 in. [3 mm] in diameter), but at least one species grows larger than 3 ft (1 m). Ctenophores live in almost all ocean regions, floating freely in the water. All comb jellies except one parasitic species are carnivores, consuming young mollusks, crustacean and fish larvae, copepods, and other zooplankton.

The Bloodybelly Comb Jelly (Lampocteis cruentiventer) is a variety of Ctenophore (simple marine animals), commonly known as comb jelly. Despite its name, this particularly stunning comb jelly ranges in body color from deep red to pale to deep purple, sometimes black. Scientists believe that the deep color of its belly helps mask the Bloodybelly Comb Jelly's bioluminescence from potential predators.
