ctenophoreor comb jellyAny 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. How to thank TFD for its existence?

| The most likely candidates for biocontrol include Baroe, another ctenophore that eats only comb jellies, and the butterfish, a fish of low commercial appeal with a fairly catholic diet that includes Mnemiopsis. Included in the new assemblage of more than 1,000 specimens are the first representatives of modern chaetognaths (arrowworms) and ctenophores (jellyfish). |
