Trachichthyidae

Slimeheads, also known as roughies and redfish, are mostly small, exceptionally long-lived, deep-sea beryciform fish constituting the family Trachichthyidae, coming from the Ancient Greek τραχύς (trakhús), meaning "rough", and ἰχθύς (ikhthús), meaning "fish". Found in temperate to tropical waters of the Atlantic, Indian, and Pacific Oceans, the family comprises about 50 species in eight genera. Slimeheads are named for the network of muciferous canals riddling their heads.

Gephyroberyx is a genus of fishes in the slimehead family.
