The knifetooth dogfish (Scymnodon ringens) is a little known deepwater shark that is observed at depths of 200-1,600 metres in the eastern Atlantic (Scotland down to Mauritania and Senegal). According to reports they are common in this range but rarely caught as bycatch from commercial trawls or deep-water surveys off of western Scotland.
Here's a cool #finfact: The knifetooth dogfish is not included in the list of species covered by the European Union Total Allowable Catch for deepwater sharks, and is not covered by fisheries measures. A small shark (getting up to 1.1 metres), they are black, have green eyes, and small dorsal fins (and small spines to match). With narrow pectoral fins, a short snout, and knife-cusped teeth in lower jaw to go for its... well, unknown prey. But those teeth may show that they can go after large prey. Another #finfact about these animals: no anal fin!
We don't know much else about these animals- including reproductive methods. They are most likely viviparous with yolk sac. The IUCN assessed these animals as Data Deficient (DD).
