is often mistaken for a jellyfish, but it actually has its own Phylum,
Ctenophora and is only remotely related to the Cnidaria. Although
comb jellyfish do have tentacles they are unable to sting. The tentacles
are "sticky" and are used to catch their prey, such as large crustaceans
and even small fish.
Eight rows of cilia
are used for locomotion and most species are dictated by currents
where to go. However, some species do attach themselves to substrate
or benthic organisms such as sponges, seacucumber or anemones.
