The Alien Sharks – named for its huge fang-like teeth – was caught in the Pacific Ocean near Taiwan.
Using its terrifying mouth, it can swallow larger fish totally whole with a quick fiendish snap.
It is an incredibly rare species, with only a handful of the glow-in-the-dark sharks being caught since they were discovered in 1986.
With its large teeth, snapping jaws, and jet-black bug-eyed looks, the creatures hold an eerie resemblance to the Xenomorphs from the Alien franchise.
Taiwan’s Fisheries Research Institute revealed it has now picked up five of the creatures in a survey near Donghe Township.
Little is known about the viper shark, but they are believed to live around 1000 feet in the darkness of the ocean.
They are believed to travel up to 500 feet deep during the night.
Scientists have now caught a living specimen, however the creature died within a day of being placed into a tank.
Viper sharks mainly enjoy a diet of crustaceans and bony fish, including lanternfishes – believed to be attracted by the predator’s glowing body.
The species was first discovered in 1986 off the coast of Shikoku Island, Japan, by the bottom-trawler, Seiryo-Maru.
Its scientific name Trigonognathus kabeyai honours the fishing vessel’s captain, Hiromichi Kabeya.
The creatures are also relatively small – with the largest known example being just 21 inches long.
It is one of many very strange undersea creatures found in the depths of the ocean.
Video of a mysterious sea creature, believed to have been a type of squid, changing colour was revealed last week.
