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. Mnemiopsis leidyi appeared in the Black Sea in 1982, connected to the Gulf of Mexico seeding population, occurred in 1982 (Pereladov, 1988), the invader then rapidly spread through the whole Black Sea and the Caspian Sea and was found at the turn of the century in various Mediterranean basins (Shiganova et al., 2019 and references included). Ctenophores Mnemiopsis leidyi reacts to a sharp change in light intensity as a stress stimulus.. Directional movement towards or away from light is a lack in adult M. leidyi..
