Range of longsnout dogfish (in blue) |
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]
In June 2018 the New Zealand Department of Conservation classified the longsnout dogfish as "Data Deficient" with the qualifier "Secure Overseas" under the New Zealand Threat Classification System.[3]
