Whereas most medusae grow to adult size before beginning These cilia easily refract light and cause pulsing rainbows to travel along their body. Contentious relationships in phylogenomic studies can be driven by a handful of genes. This illustrated key includes the common species found not far offshore of the American west coast, from intertidal and shallow water strandings to open ocean surface and deep water. There are probably about Recently some scientists are including the very dissimilar salps under the word-umbrella "jellyfish", but the salps, which are chordate-herbivores in the subphylum Tunicata, and have their own closer-relatives including doliolids, pyrosomes, and appendicularians (larvaceans), are really not jellyfish in any traditional sense of the word.

Not all ctenophores are bioluminescent: Pleurobrachia. Even with all possible precautions in place to assure A carnivorous predator on edible zooplankton (including meroplankton), pelagic fish eggs and larvae, M. leidyi causes negative impacts right through the foodchain of the areas it has invaded. Up to 100 animals per cubic metre were counted in the Baltic, whereas the population density in the North Sea was at a much lower 4 animals/m3 at most. 156, 537551 (1993).
