To fill the void regarding the availability of high-quality, genome-scale sequence data in this part of the evolutionary tree, we have sequenced, assembled, annotated, and performed a preliminary analysis on the 150 megabase genome of Mnemiopsis. The comb jelly has the capacity for self-fertilization, as they are hermaphroditic. Carr, D., Rouvire, C. & Sardet, C. In vitro fertilization in ctenophores: sperm entry, mitosis, and the establishment of bilateral symmetry in Beroe ovata. 193, 245247 (1997). These comb plates are the largest known ciliary structures in the animal kingdom, and ctenophores are the largest animals that swim by means of cilia.
