Trachyrincidae is a family of gadiform fish. The subfamily contains four genera found in Atlantic, Indian and Pacific Ocean. These species live in deep-water. These fishes have a long, narrow and sharply pointed snout. The chin barbel is present. Two genera (Macrouroides and Squalogadus) have a huge and rounded head with the consistency of a water-filled balloon. The eyes are tiny. The chin barbel is absent.
The former subfamily Macrouroidinae is now considered synonymous with Trachyrincidae.
