Do not expect the animals in Mariana Trench to look like the usual fish you see because they don't. In fact, you'll be surprised at how terrible they look and might find some scary and be surprised at their lifestyle.
Popular Animals in Mariana Trench
Marian Trench has many animals, but we will share five of the weirdest creations in the deep.
1. Goblin Shark (Mitsukurina owstoni)
Only little is known about them because they live so deep, and only a few specimens were discovered. In fact, it's rare to encounter them because they don't live within our reach.
The ampullae of Lorenzini, along with their snouts, are a sensory organ that allows them to pick up weak electrical impulses in the water, such as the passing pulses of possible prey. If they come within reach of a victim, their jaws catapult forward violently and pierce it with teeth that resemble needles and have evolved for spearing rather than cutting.
2. Black seadevil (Melanocetus)
Fans of Finding Nemo may be familiar with the fearsome black seadevil, an alien-like anglerfish that employs a bioluminescent lure to attract food in the deep sea's gloom. The Monterey Bay Aquarium Research Institute (MBARI) first documented a black seadevil in motion in 2014.
Black seadevils normally measure around 20 centimeters (8 inches) in length. Yes, they are not that big, but their scary appearance, gaping mouth, and sharp teeth will blow you away.
3. Dumbo octopus (Grimpoteuthis)
The dumbo is the deepest-living octopus, moving across the deep ocean. They flap their ear-like fins and use their arms to steer so that they can move around.
Since females will carry eggs at various stages of development, they have evolved into the ultimate opportunists to survive the poor dating climate of deep-sea life. They are ready to cross with a male and can store sperm until the right circumstances arise for conception.
4. Vampire Squid
Vampire squid got their name from the sanguine hue that reminded people of the fabled undead bloodsuckers. They also have a cape-like webbing of skin between their arms.
They are not immortal, but because they live more slowly and in open ocean environments at depths of 500 to 3,000 meters (1,600 to 9,800 feet), they survive longer than most cephalopods.
Life at this depth is more about floating than swimming, meaning you require a little oxygen and can survive on zooplankton and other low-calorie debris. Along with having multiple reproductive cycles while other species only have one, the vampire squid has a more active sex life than most cephalopods.
5. Zombie worms (Osedax)
Zombie worms are huge fans of dead bodies, particularly those of whales. Osedax, which means "bone eater," alludes to how these worms would pierce through corpses to get the fatty lipids trapped inside their skeletons. Zombie worms were first discovered at an extraordinary depth of 3,000 meters (10,000 feet), and their desire for whale wrecks and other dead creatures led to their evolution to occupy life on the seafloor.
A productive zombie worm relies heavily on collaboration, with the females doing most of the labor. Acids are used to drill into the bone, liberating the lipids for processing by symbiotic bacteria.
It may be argued that the male isn't doing his share, but given that he is a microscopic organism trapped inside the female's body, possibly just one of the hundreds, it's probably unreasonable to expect much more than sperm.
What Is Mariana Trench?
Mariana Trench is the deepest location on Earth. According to National Geographic, while thousands have successfully climbed Mount Everest, the highest point on Earth, only two individuals have descended to the Challenger Deeps in the Pacific Ocean's Mariana Trench.
It is located in the western Pacific east of the Philippines and approximately 124 miles east of the Mariana Islands. It is a crescent-shaped scar in the Earth's crust, 1,500 miles long and 43 miles wide.
As part of the first global oceanographic trip, the British ship H.M.S. Challenger explored the Mariana Trench for the first time in 1875. Using a weighted sounding rope, the Challenger's scientists measured a depth of 4,475 fathoms(nearly five miles or eight kilometers). The H.M.S. Challenger II, a British ship, returned to the area in 1951 with an echo sounder and determined a depth of about 7 miles (11 kilometers).
