SpawningIn the Japan Sea, it was estimated that a female spawns about 5,500-13,000 eggs in summer.
EggsEggs are oval, weakly greenish tint.
This species seems to be a mesopelagic boundary species associated with continental or island shelves (Tsuchiya, 1993; Young, 1995). It is distributed from off the Philippines, East China Sea, Japanese coast of Japan Sea, Kuroshio-Oyashio transition zone to near Hawaiian waters.
