Chromosome-scale genome assembly of brownspotted flathead Platycephalus sp.1 provides insights into demersal adaptation in flathead fish

Flatheads are valuable commercial fish species endemic to the Indo-West Pacific.Due to their economic value and unique biological traits,such as metamorphosis and camouflage,they serve as ideal marine organisms for studies on demersal adaptation and evolution.The brown-spotted flathead(Platycephalus sp.1)is the most widely distributed in the northwestern Pacific.Despite the lack of a valid scientific name,it has been long recognized and exploited in the marine fisheries of China,Japan,and Korea.In the current study。
