Deepest Sea Creatures Will Make Your Body Go Cold

450 million years ago, no I wasn’t around then the sea level was higher coral reefs started to form.

The climate on our planet was stable and warm. Not even dinosaurs were around yet. The time when bony and jawed fish we know as sharks appeared, they’ve been dominating the oceans and making other marine creatures flee in fear ever since.

Many of them like great white sharks have evolved and adjusted to life in the open ocean. As hunters with a pretty high position in the food chain. They’re less diverse today than before. One of the reasons is the asteroid strike from the age of dinosaurs, after it reduced the number of shark species, only smaller in deep water kinds that eat primarily fish survived, these started getting bigger over time. near the surface, sharks such as Mancos, or great white ones, develop faster movements, and are somewhat between gray and blue to blend in with their surroundings.

The epilate shark can even walk on the land, it can’t take a walk on the beach because it can’t breathe outside of the water. But it lives on coral flats in shallow tropical waters, so it can walk in kind of a crawling motion.

But deep down below, there are mysterious alien looking often cute shark species that didn’t come to the surface, which is why they didn’t need to adjust to the new environment and different conditions.

They haven’t changed a lot through time. So there are some living fossils. These creatures mostly don’t have five gill slits, the most common number, but six or seven. It’s because there’s less oxygen, the deeper you go in the ocean, so they need more gills let’s sharks on the surface evolved to have fewer gill slits.

Six skill sharks are the most primitive sharks we have today. Their skeletons are like those of ancient extinct sharks, and they can survive only in very deep waters. like cats, sharks have a layer of reflective cells placed inside their eyes, which helps them see better in the dark, deep sea or cloudy waters. Sharks on the surface have big eyes because they evolved to hunt in the sunlight. So they tend to rely on their vision.

Those that live in shallow waters have small eyes so they can protect themselves from the sand. Like some other deep sea creatures.

Six Gill sharks also have bigger eyes to take in as much light as possible. They have more light sensing rods, but don’t distinguish colors that well. In the oceans twilight zone with a minimum of sunlight. There’s a couple of bioluminescent shark species they don’t take in light within their eyes, but produce or re emitted with their bodies. Their skin or organs have specialized cells that produce a soft blue green light. deep sea creatures that produce their own light do that to attract their prey, deter animals from going after them, or scientists thing communicate with each other. It can even help them to camouflage.

They do it by hiding their silhouettes from animals going after them. They produce enough light to match their surroundings. The biggest luminous underwater creature is the kite fin shark found swimming 980 feet below sea level preying on ground fish or smaller sharks. It can grow almost six feet long and lives 3200 feet below sea level.

Deep Sea sharks are also bigger than those on the surface, the Greenland shark and grow up to 24 feet long, bigger than a great wide. There’s a thing called Deep Sea gigantism. creatures and nutrient poor depths of the ocean grow bigger because that way they lose less energy as heat. The Greenland shark lives its life in slow motion. It has a slow metabolism and can go very long periods without food. With their slow pace. They evolved to live up to 500 years at depths of 7200 feet.

Sharks in shallow waters catch their prey relying on agility and speed. But for them, it’s easier because there’s plenty of food on the surface. Deep Sea sharks with less food and slower life rhythm had to develop a different style. They’re more opportunistic, definitely not picky and don’t care if their future meal is alive or not. frilled shark jar, another living fossil from the darkest depths hasn’t evolved much through time. And they’re one of the last of their kind with all of their relatives already gone extinct.

It grows up to seven feet long, primarily hunts on squid and catches other sharks and fish. It looks like a dinosaur, a snake like phase along smooth in body that moves in a serpentine way. It can propel itself with a power of its tail and curl like snakes. They don’t swim in a straight line like other sharks. Cookie Cutter shark rose up to 20 inches.

It got the name because of the way it feeds biting off small pieces. It’s a parasite creature, which means it feeds off bigger animals but leaves them alive. They have sharp teeth and sometimes even swing Those that fall off on purpose. Some researchers think it could be because they live in the depths that are nutrient poor. If they swallow the teeth, they could recycle calcium and other material from it. privly shark is a rare and unusual creature with many Thorn like denticles and two small dorsal fins.

It lives mostly in the depths of the Pacific region, up to 1900 feet goes sharks are not even real sharks, but fish closely related to them and rays. They have big pectoral and pelvic fins to dorsal fins, pretty big eyes, and unlike their cousins have a single external Gill opening. Ghost sharks have slender tails and can grow up to 80 inches silver to blackish color. They sometimes live in rivers and coastal waters, but also in the depths of the ocean of 8200 feet, or even deeper. They are pretty weak swimmers, so they tend to feed on invertebrates and small fish. Goblin sharks swimming through the deep sea.

This creepy shark with a flabby body suddenly sees a small innocent squid. It goes toward it, but the potential snack notices it and quickly starts moving to Dart away. It seems like a plan could work at first, but then the shark suddenly thrust the jaw of its mouth and catches the poor little squid in a second. After the meal is finished, the animal simply fits the jaw back into the mouth and goes away as if nothing happened.

This is possible because it has a jaw connected to three inch long flaps of skin, which is why it can unfold from the snout. It can grow up to 12 feet long with a weight of 460 pounds. Scientists think Goblin sharks are mostly active in the morning and evening.

The shark has a long prominent snout and specific sensing organs on it. It uses them to sense electrical fields in the dark oceanic depths. Seven Gill shark is a big cow Shar brown to silver gray on top, white underneath black and white spots with a thick body a small dorsal fin and a wide blunt snout. It can grow up to 10 feet long, mostly lives in the depth of 1800 70 feet. But you can also find it in deep channels and bass.

It can be aggressive towards humans if provoked, so don’t like most deep sea creatures. It’s an opportunistic hunter that’s not quite picky, but likes to go after dolphins, seals, porpoises and other marine animals. mega mouth sharks mostly live in the depths of 15,000 feet and spend most of their time in the dark like me. Scientists discovered it in 1976 because it went near the surface at night to feed on zooplankton.

That’s the only time the sharks go there. During the day they return to their quiet, dark and mysterious depths. They are filter feeders, which means they keep their mouths wide open while swimming, so they filter the plantains they like to eat. There are organs that produce light inside of their mouths, which attracts potential prey such as pelagic crustaceans.

These sharks live in the deep parts of the ocean, but you can rarely find them below almost two miles. Scientists think some other stronger bony fishes out competed though. Deep parts of Oceans became oxygenated around 70 million years ago, and sharks have been around way longer. But bony fishes adjusted and adapted efficient ways to use oxygen. While sharks were slow with adaptations, so they lost.

Also oceanic depths are way colder, which is challenging for fish and the rest of cold blooded animals because the speed of their metabolism widely depends upon the external temperature.
