The Southern driftfish or ragfish, Icichthys australis, is a medusafish of the genus Icichthys found circumpolar in all southern oceans between latitudes 50Â° S and 60Â° S, from the surface down to 1.24 mi (2,000 m). Its length is from 13.78 to 31.50 in (35 to 80 cm).
The southern driftfish is similar to the rudderfish, and has soft easily-damaged fins, large eyes, and a small flexible mouth. Its flesh is soft and its bones are weakly ossified, giving rise to its second common name as it has the limp feel of a rag doll.
Its color is a uniform dark brown with black eyes.
