Northwest Pacific: southern Hokkaido to Kyushu and the southern Korean Peninsula (Ref. 559). Three morphotypes observed (reddish type; blackish type; brownish type), and may be reproductively isolated from each other (Ref. 44259).

Biology     Glossary (e.g. epibenthic)

Juveniles associate with drifting seaweed. Plankton feeder (Ref. 12114, 12115). Viviparous (Ref. 34817).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Males established territories ranging from 12 to 70 sq. m; initiated courtship when females approached the territories; lateral display, rushing and turning movements were frequently observed during courtship. Mating pair formed about 30 min before copulation; the pair ascended to 1.5-2.0 m above bottom then males suddenly coiled around the body of females to copulate.
