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. meaning that a single ctenophore carries both male and female cycle in the plankton, so they are considered to be "holoplanktonic".

Mnemiopsis leidyi is an actively hunting lobate ctenophore (comb jelly) with a translucent body reaching 12 cm in length (NIMPIS 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. Mnemiopsis leidyi (Agassiz 1865) is a ctenophore native to the east coast of North and South America (Gesamp 1997) and a successful invader, with a range spanning from the Black Sea to the.

Mnemiopsis leidyi was introduced in the Black Sea in the 1980s, where only one species of comb jelly, the small sea gooseberry Pleurobrachia pileus occurred until then. As adults, they lack tentacles and can grow to several inches in length. In its different successive stages of life . (small size).
