The silver spinyfin (Diretmus argenteus) is a deep-sea spinyfin found across the world’s oceans (except the Mediterranean Sea) at depths reaching about 2,000 m. It belongs to the family Diretmidae and is the only species in the genus Diretmus. Adults usually reach 13–40 cm in length depending on the measurement type.

Range & habitat
The silver spinyfin lives in tropical and temperate oceans around the world but has not been found in the Mediterranean. It is a deep-sea fish, found mainly between 300 and 1,200 m deep, sometimes down to 2,000 m. Adults usually live in midwater or near the bottom (benthopelagic zone), while larvae drift in surface plankton before moving deeper as they grow. It has been recorded off the coasts of Australia (Western Australia, New South Wales, Victoria, Tasmania), and throughout the Atlantic, Pacific, and Indian Oceans. Although it is widely distributed, it is rarely caught and not considered abundant.
