主　　题：Cephalopoda Evolution Flying squid Genome Photophore 

摘      要：Pelagic cephalopods have evolved a series of fascinating traits,such as excellent visual acuity,high-speed agility,and photophores for adaptation to open pelagic ***,the genetic mechanisms underpinning these traits are not well ***,in this study,we obtained high-quality genomes of two purpleback flying squid species(Sthenoteuthis oualaniensis and Sthenoteuthis sp.),with sizes of 5450 Mb and 5651 Mb,*** genomic analyses revealed that the S-crystallin subfamily SL20-1 associated with visual acuity in the purpleback flying squid lineage was significantly expanded,and the evolution of high-speed agility for the species was accompanied by significant positive selection pressure on genes related to energy *** molecular signals might have contributed to the evolution of their adaptative predatory and anti-predatory *** addition,the transcriptomic analysis provided clear indications of the evolution of the photophores of purpleback flying squids,especially the recruitment of new genes and energy metabolism-related genes which may have played key functional roles in the process.
