Snaggletooth
There are any number of small, deep sea stomiid fish in this genus of Astronesthes. They have a bioluminescent red chin barbel which is used as a lure to attract small prey and they also have delicate skin, and mouths that are filled with sharp, needle-like, curved teeth. Freaky.
Deep Sea Pompeii Worm
Ugh, meet the species of deep sea polychaete worm (which is commonly referred to as “bristle worms”). It can be found only at hydrothermal vents in the Pacific Ocean, and was discovered in the early 1980s off the Galápagos Islands by French marine biologists.
