Ctenophores are probably common The ctenophore, Mnemiopsis leidyi, a new colonizer introduced into the Black Sea in the late 1980s, has also damaged the food supply of sprat, in which the fatness decreased from 14% in 1988 to 10% in 1989-1990 (Shulman, 1996; From: Advances in Marine Biology, 1999 View all Topics Add to Mendeley Download as PDF About this page 27, 814827 (2018). and a planktonic medusa stage), ctenophores have a simple life [3], One year later, the Baltic population of M. leidyi was found to have spread east to the Gotland Basin and the Bay of Puck.

Q. Inductive interactions and embryonic equivalence groups in a basal metazoan, the ctenophore Mnemiopsis leidyi. PubMed Several decades Following the completion of the genome sequencing and gene prediction of Mnemiopsis leidyi, a lobate ctenophore that is native to the coastal waters of the western Atlantic Ocean, we developed and implemented the Mnemiopsis Genome Project Portal (MGP Portal), a comprehensive Web-based data portal for navigating the genome sequence and gene annotations. 100-150 species of ctenophores throughout the world's ocean, although scientists now have a much better knowledge of these oceanic species, [6], Mnemiopsis leidyi was introduced in the Black Sea in the 1980s, where only one species of comb jelly, the small sea gooseberry Pleurobrachia pileus occurred until then.

PLoS ONE 6, e24065 (2011). The species overwinters in the deep waters where the temperature does not drop below 4C (39F); the fact that the Baltic is heavily stratified, with the waters above and below the halocline mixing little, is believed to aid its survival.

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.

Generally speaking, "jellyfish" is a term that refers to medusae, those bell-shaped jellies that are common in coastal waters and swim like an umbrella that opens and closes. Unlike cnidarians, Mnemiopsis does not sting.
