ISSN 1750-2799 (online) The presence of a functionally tripartite through-gut in Ctenophora has implications for metazoan character trait evolution. Lesser known species include the lobe-flapping Ocyropsis, which does a kind of frog kick with its feeding lobes for locomotion. tentacles that are used roughly like fishing lines for capturing University of Washington A rapid 3-week egg-to-egg generation time makes Mnemiopsis suitable for a wide range. Ctenophores are distinguished from all other animals by their eight rows of comb plates, which are their primary means of locomotion. examined, it appears that ctenophores reproduce at a young age To address this problem, we have developed straightforward protocols that can be easily implemented to establish long-term multigenerational cultures for biological experimentation in the laboratory.
