The ribbonfish are any lampriform in the family Trachipteridae. These pelagic fish are named for their slim, ribbon-like appearance. They are rarely seen alive as they typically live in deep waters (though are not bottom feeders).

They are readily recognized by their anatomy: a long, compressed, tape-like body, short head, narrow mouth and feeble teeth. A high dorsal fin occupies the whole length of the back; an anal fin is absent, and the caudal fin, if present, consists of two fascicles of rays of which the upper is prolonged and directed upwards. The pectoral fins are small, the pelvic fins composed of several rays, or of one long ray only. They have heavy spines along their lateral lines, and numerous lumps in the skin.[1] Ribbon fish possess all the characteristics of fish living at very great depths. Their fins especially, and the membrane connecting them, are of a very delicate and brittle structure. In young ribbonfish some of the fin-rays are prolonged in an extraordinary degree, and sometimes provided with appendages.

Specimens have been taken in the Atlantic, the Mediterranean,they have been found in Bay of Bengal, at Mauritius and in the Pacific. The species from the Atlantic has occurred chiefly on the northern coasts, Iceland, Scandinavia, Orkney and Scotland. The north Atlantic species is known in English as deal fish, in Icelandic "vogmær" and Swedish vågmär. Its length is usually 5 to 8 feet (1.5–3.5 m), but it can sometimes be found at over 20 feet. Specimens seem usually to be driven to the shore by gales in winter, and are sometimes left by the tide. S. Nilsson, however, in Scandinavia observed a living specimen in two or three fathoms (4–5 m) of water moving something like a flatfish with one side turned obliquely upwards. A specimen of Trachipterus ishikawae was discovered on a beach in Kenting, Taiwan in November 2007, alive but with a 10-cm cut wound to its side, and was returned to deeper water.

The species, Trachipterus ishikawae, is commonly called "earthquake fish" in Taiwan because the fish are popularly believed to appear following major earthquake events due to alleged sensitivity to disturbances in the ocean floor. There are records of such appearances following a 100-year earthquake in Hengchun in late 2006 and in Taidong in 2007, as well as the numerous recent March 2010 sightings along the coast of Japan, but other recorded sightings do not correspond with seismic disturbances.
