Comb Jellies are often mistaken for jellyfish, but they are not. One main difference between them is that ctenophores do not have stinging cells. They are, however, gelatinous zooplankton as jellyfish are.
Ctenophores have eight rows of comblike plates arranged longitudinally around the body. These combs move the ctenophore forward. They have a mouth, a stomach, but no anus.

Two types of ctenophores are: Pleurobrachia and Beroe.
