<em>Todarodes pacificus</em> is a cephalopod mollusk in the family Ommastrephidae, order Oegopsida, commonly known as the Japanese flying squid or common flying squid. The species is classified as Least Concern on the IUCN Red List. <em>Todarodes pacificus</em> is native to Asian waters, with documented occurrences including Taiwan, and is widely distributed across the northwestern Pacific Ocean. This species is one of the most commercially important squid species in the world, supporting major fisheries in Japan, China, and South Korea. It typically inhabits open ocean environments from the surface to mesopelagic depths, undertaking extensive diel vertical migrations. The common name refers to the ability of this species to leap from the water and briefly glide through the air, propelled by jets of water and using its fins and outstretched tentacles for lift — a behavior observed in several ommastrephid squids. Populations exhibit distinct migratory patterns linked to oceanographic conditions and spawning cycles. Biological traits of this species remain poorly documented in the scientific literature.
