Ctenophores are distinguished from all other animals by possession of sticky cells called colloblasts and their eight rows of cilia. This sequencing effort has produced the first set of whole-genome sequencing data on any ctenophore species, and is amongst the first wave of animal genomes to be sequenced de novo using solely next-generation sequencing technologies. Reassessing embryogenesis in the Ctenophora: the inductive role of e1 micromeres in organizing ctene row formation in the mosaic embryo, Mnemiopsis leidyi. can only be seen in darkness.

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).

By 1989, the Black Sea population had reached the highest level, with some 400 specimens per m3 of water (>10 animals/cubic foot) in optimal conditions. animal that is simple to maintain and interesting to watch. 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.
