Description

The Japanese velvetfish is a velvetfish (Aploactinidae), related to the scorpionfishes, from coastal waters of the northwest Pacific, off East Asia. The species grows to about 12 cm and has a stocky, brownish body with a velvety skin of fine prickly scales and a high dorsal fin starting far forward. As an ambush hunter it shelters motionless on soft bottoms. The dorsal-fin spines carry venom and can cause a painful sting; handle with care.
