gelatinous, aquatic invertebrate also known as a “comb jelly”. They use rows of cilia (“combs”) to swim. Most species have eight strips, called comb rows, that run the length of their bodies and bear comb-like bands of cilia, called “ctenes”. When the cilia beat, those of each comb touch the comb below . The name “ctenophora” means “comb-bearing” in Greek.
