Active studies of the underwater world began relatively recently—not even 100 years ago—after scientists were able to invent things like sonar, scuba equipment, bathyscaphes, and even orbital satellites. The depths of the sea have revealed countless surprises. The diversity of life forms is simply astonishing, even though a lot of them look quite unsettling.
Meet the most terrifying, strange, and alien-looking deep-sea creatures that humanity has discovered.
1. Angler fish
Discovered in 1930, these bizarre ocean dwellers prefer the darkest waters where the sunlight can never reach them. Angler fish use a special appendage that glows on their forehead to lure their prey. Thanks to its special metabolism and extremely sharp teeth, it can eat anything it comes across, even if the victim is many times larger. Its mating rituals are also quite bonkers. Given the extremely harsh conditions and rarity, the male, who is ten times smaller than the female, attaches himself to the flesh of his chosen one and makes the “transfer” through the blood.
2. Pelican eel
This fish, with its absurdly large mouth and tiny body, resembles a creature from a horror movie. Its massive, pelican-like jaws can open wide enough to swallow prey much larger than itself. Unlike other eels, this one uses its mouth as a giant sack to gather food from the murky depths of the ocean. It also has a bioluminescent tail that it uses like a glowstick to lure in unsuspecting prey. Although it looks intimidating, it’s actually a master of stalking, relying on the darkness and its glowing appendage to do all the work for it.
3. Vampire squid
Despite its fearsome name, the vampire squid is not a predator. This otherworldly creature, which lives in the oxygen-poor depths of the ocean, has a pitch-black body and eerie webbed arms that glow in the dark. Instead of feeding on live prey, the vampire squid feasts on dead plankton, feces, and other particles that drift from the upper parts of the ocean. Equipped with light-producing organs called photophores, the vampire squid puts on a dazzling show to confuse predators and slip away into the abyss.
