The Grammicolepididae are a small family of deep-sea fishes, called tinselfishes due to their silvery color.
They are related to the dories, and have similar deeply compressed bodies. The largest species, the thorny tinselfish, Grammicolepis brachiusculus, grows up to 64cm (25inches) long.
They are found in isolated areas of the Atlantic and Pacific Oceans, where they inhabit deep waters: they have been found down to about 1000m (3,000feet). They are rarely caught in trawls. Five have been caught south of the Bay of Biscay. One was caught off Scotland in 2004, and one off County Kerry, Ireland in December 2010 by Rossaveal trawler "Maria Magdelena III"
