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?

| On the other hand, Breitberg has found that the Bay's gelatinous species--its comb jellies (Mnemiopsis leidyi) and stinging sea nettles (Chrysaora quinquecirrha)--are quite tolerant of hypoxia. First identified in 1982, populations of these comb jellies (Mnemiopsis leidyi) soon swelled to dramatic proportions, contributing to the 1989 crash of the Black Sea's largest surviving fishery: anchovies. |
