A number of studies on Mnemiopsis have led to a better understanding of many key biological processes, including regeneration and axial patterning, and these studies have contributed to the emergence of Mnemiopsis as an important model for evolutionary and developmental studies. In 2006, it was first recorded in the North Sea,[10] and since October 17, 2006[11] in the western Baltic Sea, namely the Kiel Fjord and The Belts. The cilia in each row are PubMed Central Experiments on germinal localization of the egg of Beroe ovata. 10, 357398 (1874).
