Description

The common icefish or noodlefish is a very slender, almost transparent fish of the family Salangidae (icefishes) reaching about 10 cm. The glass-clear, scaleless body recalls a glass noodle; the species remains larva-like in build throughout life (neoteny) and is almost invisible in the water. It comes from East Asia and lives in coastal and estuarine water around Japan, Korea and the Russian Far East. It is amphidromous: it shuttles between sea, brackish and fresh water and migrates to fresher water to spawn, where most individuals spawn once and then die. In schools it filters small zooplankton. In East Asia it is a valued delicacy, eaten fresh or dried.
