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.Iwamoto, T., Nakayama, N., Shao, K.-T. & Ho, H.-C. (2015): Synopsis of the Grenadier Fishes (Gadiformes; Teleostei) of Taiwan. Proceedings of the California Academy of Sciences, (Series 4), 62 (3): 31-126. 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.Iwamoto, T., Nakayama, N., Shao, K.-T. & Ho, H.-C. (2015): Synopsis of the Grenadier Fishes (Gadiformes; Teleostei) of Taiwan.

The former subfamily Macrouroidinae is now considered synonymous with Trachyrincidae.
