Sometimes though, for convenience, scientists lump medusae and ctenophores together and call them both "jellyfish", when the scientists are trying to make a point about these two groups of unrelated organisms that are ecologically very similar and often found in the same places (see also the paragraph just above this one). 189, 190192 (1995). 212, 338348 (2002). 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.
