The silver spinyfin, Diretmus argenteus, is a spinyfin of the genus Diretmus, found around the world except the Mediterranean, at depths down to 2,000 m. Their length is between 30 and 40 cm.
The silver spinyfin is a widely distributed but rare species with a flattened disc-shaped body with a sharp scute-covered edge on the belly. A large upturned mouth and huge eye dominate the front half of the disc and a small forked tail projects from the other. They are oviparous and the larvae spend time in the plankton.
It has small spiny scales but no lateral line and is a uniform silvery colour, the top of the back being black.
