The deeper the ocean goes, the less it is studied. This is explained by the fact that the deeper you dive, the greater the pressure. While the human limit is a maximum
of two hundred meters, drones made of strong alloys have a much higher limit. For example, the record holder was able to dive to 11,000 meters. It is these drones that
have given the world images of creatures that have adapted to pressures so terrifying that even the best human technology can destroy them.
Some of deep Ocean creatures known to mankind:
Vampire squid
The vampire squid (*Vampyroteuthis infernalis*, which literally translates to "vampire squid from hell") is perhaps one of the most misunderstood creatures
in the ocean. Despite its sinister name, it is an incredibly cool and peaceful animal.
A Living Fossil (A Genetic Outlier) The vampire squid is neither an octopus (which has eight tentacles) nor a squid (which has ten).
It is so unique that scientists had to assign it its own distinct order: Vampyromorphida. It is the only surviving member of this order on Earth—a
relict species that has remained virtually unchanged for 300 million years (it was swimming the oceans even before dinosaurs appeared!).
A Master of Survival in the "Dead Zone" It inhabits depths ranging from 600 to 900 meters—a region known as the Oxygen Minimum
Zone. Oxygen levels there are so low that most other animals would simply suffocate. However, the vampire squid possesses an incredibly slow metabolism
and unique blood (which uses copper instead of iron, giving it a bluish hue) that binds even the tiniest amounts of oxygen with extreme efficiency. As a
result, it has virtually no natural predators in this environment.
Fishing rods instead of jaws Since expending energy on active hunting is not an option in the oxygen minimum zone, it has found a brilliant
solution. It possesses two long, slender filaments that can be retracted into special pockets on its body. It simply hovers in the water, extends these "fishing rods,"
and waits for "marine snow"—dead plankton, bits of algae, and excrement slowly drifting down from above—to adhere to them. It then scrapes this food off with
its tentacles and conveys it to its mouth.
The "Pineapple" Posture Scientists amusingly refer to that "Dracula’s cape" trick as the "pineapple posture." When the
vampire gets startled, it turns its webbed tentacles inside out and wraps them around its body. The inner surface of the tentacles is
studded with fearsome-looking (yet completely soft and harmless) spiky projections. In this pose, the creature resembles a prickly, inedible ball to a predator.
A Light Show Instead of Ink Releasing ink in the pitch-black darkness of the deep ocean is pointless. That is why the vampire
squid’s body is covered in photophores (light-producing organs). False eyes: It has two large spots on the top of its head that it can turn on and off. If a
predator attacks, the vampire squid extinguishes these glowing "eyes" and slowly contracts, creating the illusion that it has rapidly swum away into the distance.
Black Dragon Fish
The Black Dragonfish (Idiacanthus atlanticus) is one of the most alien-looking predators lurking in the deep ocean. With its long, snakelike body and a mouth full of
terrifying, needle-sharp teeth, it looks like a creature straight out of a nightmare. However, beneath this fearsome appearance lies a fascinating story of extreme
survival in the pitch-black depths.
Sexual Dimorphism Among black dragonfish, the females are truly terrifying hunters. They are black with six stripes and possess massive fangs,
pelvic fins, and a specialized chin barbel. The males, however, are completely different: they are brown, lack teeth entirely, and have no pelvic fins or chin barbel.
Nighttime migration of females Female dragonfish lead highly active lives. Every night, they undertake a massive vertical migration, ascending from
depths of over 500 meters—where they hide during the day—to the uppermost waters. In contrast, the toothless males never migrate, remaining permanently in thepitch-black
darkness at depths below 1,000 meters.
Tiny Weight Although these creatures look like giant, eerie sea monsters in close-up photos,
they are actually incredibly light. They weigh only 13 to 15 grams.
MonkFish
The Monkfish, often referred to as the "sea devil," is a master of ambush that looks like a creature from a prehistoric
nightmare. With its enormous, flattened head, massive mouth filled with inward-pointing teeth, and mottled skin, it
perfectly camouflages itself against the ocean floor. But do not let its grumpy appearance fool you - this bizarre fish
is one of the ocean's most patient, fascinating, and deadly predators.
The Built-In Fishing Rod (The Lure)Unlike predators that chase their food, the monkfish brings
the food to itself. It has an elongated spine on its head that acts just like a fishing pole. It dangles a fleshy
piece of tissue right above its jaws, wiggling it to mimic a small, injured animal. When a curious fish comes to
investigate, the monkfish springs its trap!
Walking on the Ocean Floor Monkfish are notoriously lazy swimmers and prefer not to swim in
the traditional sense at all. Instead, their pectoral fins have evolved to be highly muscular and arm-like.
They use these strong fins to literally "walk" or drag themselves across the sand and mud at the bottom of the sea.
A Stomach Like a Black Hole When a monkfish decides to attack, it opens its gigantic mouth in
mere milliseconds. This incredibly fast movement creates a powerful vacuum that instantly sucks the prey inside.
Their stomachs are remarkably stretchy, allowing them to swallow creatures almost as large as themselves-including
small sharks and even diving seabirds like ducks and gulls!
Inward-Pointing Teeth (No Escape)Once something goes into a monkfish's mouth, it
does not come back out. Their terrifying, needle-like teeth are angled backward toward their throat.
This means any struggling prey only pushes itself further down the predator's throat.
