The longsnout dogfish has an extremely long, angular snout, no anal fin, dorsal fins of similar size with the first placed high on the back and the second having a longer rear free tip, and pitchfork-shaped dermal denticles. It is dark brown and grows to about 114 cm. ^[2]

Reproduction is ovoviviparous. ^[2]

This shark lives at depths between 150 and 732 m. It eats bony fish. ^[2]
