Description

The threadsail filefish is a filefish (Monacanthidae) from the northwestern Pacific, around Japan, Korea and China. The species reaches about 30 cm and has a deep, compressed, brown mottled body and a rough skin; the first dorsal spine can be raised like a thread. Juveniles shelter among drifting seaweed. As an omnivore it feeds on small invertebrates and algae. In Japan the species, known as 'kawahagi', is commercially cultured and highly prized, including for sashimi. Through its fine taste it has a high culinary value.
