Dorsale stekels (totaal) : 76 - 83; Dorsale zachte stralen (totaal) : 0; Anale stekels: 2; Anale zachte stralen: 35 - 42; Wervels: 83 - 90.
Facultative air-breathing in the genus (Ref. 126274); Found in tide pools or the intertidal zone to 20 m depth, on sandy-mud bottoms and among rocks of rocky reefs (Ref. 43239); also in eelgrass (Zostera marina) beds (Ref. 559). Sometimes to 200 m depth (Ref. 43239). Feeds on gammarids. Juveniles associate with drifting seaweed (Ref. 12114, 12115). Although rarely used for commercial food, this species is highly valued as fried fish in the spring months in Tokyo and neighboring areas (Ref. 7031).
