I saw a real life (dead) gulper eel last week. in a jar.
The gulper eel, known scientifically as Eurypharynx pelecanoides, is one of the most bizarre looking creatures in the deep sea. Its most notable attribute is the large mouth. This enormous mouth is much larger than the eel's body. The mouth is loosely hinged, and can be opened wide enough to swallow an animal much larger than itself. The hapless fish is then deposited into a pouch-like lower jaw, which resembles that of a pelican. In fact, this eel issometimes referred to as the pelican eel. The gulper's stomach can also stretch to accommodate its large meals. This giant mouth gives the eel its other common name of umbrella mouth gulper.
I also saw a Viper Fish, a type of anglerfish and the obvious inspiration for the aliens in the Alien movie series
The viperfish is one of the most unusual-looking fish in the deep sea. It is also one of the most popular and well-known species. Known scientifically as Chauliodus sloani, it is one of the fiercest predators of the deep. This fish can be easily recognized by its large mouth and sharp, fang-like teeth. In fact, these fangs are so large that they will not fit inside the mouth. Instead, they curve back very close to the fish's eyes. The viperfish is thought to use these sharp teeth to impale its victims by swimming at them at high speeds. The first vertebra, right behind the head, is actually designed to act as a shock absorber. This fearsome looking creature has a long dorsal spine that is tipped with a photophore, a light-producing organ. The viperfish uses this light organ to attract its prey through a process known as bioluminescence. By flashing the light on and off, it can be used like a fishing lure to attract smaller fish.
