What Lives In The Deepest Part of the Ocean? 7 Incredible Mariana Trench Animals

The ocean is highly considered as one of the most vulnerable and least understood places within the vast universe due that more than 80% remains unexplored in this largest body of water. The Mariana Trench is one of the most diverse ecosystems in the world. These are several Mariana Trench animals to know about.

Marianas Trench is formed through subduction of two oceanic crust that collide with each other making one piece push and pulled the other underneath – is considered as the deepest part of the ocean with about 36,032 feet estimated depth in the challenger deep.

Its distance from the surface is greatly characterized by zero visibility, great pressure, and temperatures that are extremely cold that giving scientists a difficult environment to discover and explore the unknown mystery of the Mariana Trench.

Hence, most collected data for ocean exploration has greatly relied on the advancements of technologies.

In a Western Pacific Ocean where a crescent-shaped Mariana trench found lives many beautiful however physically weird deep-sea creatures.

Let’s get to know some of them as we read this article further.

What Lives In The Deepest Part of the Ocean?

1. Barreleye Fish

It is somewhat like transparent plastic, very clear that made all the contents within its body visible. It has a transparent head filled with fluids and flat fins that allows the fish to stay still and moved precisely in the dark sea.

It is unable to live 2,500 feet below the surface as it collapsed due to a change of deep to shallow pressure.

2. Benthocodon

The uncommon type of jellyfish due to its characteristic that prefers to live in an environment far from the sea surface and far different from the usual jellyfish as it is an opaque creature. It lives beyond 2,500 feet and is oftentimes on a seafloor.

It has a rounded top termed a bell that is smaller than 2 to 3 centimeters in diameter. The reddish opaque color of the bell helps benthocodon to hide its eaten prey, especially those that are luminous, and keep them away from danger.

About 1,500 wispy tentacles in red color surround its body which helps a lot in whisking itself in the water. They feed themselves through smaller crustaceans and foraminiferans.

3. Comb jellies

Its attributes include having gelatin-like and luminous body structures, which diffract the light that may fall unto them. The name was generated from the comblike plates in its body that helped in move around the deep ocean.

This underwater animal is extra greedy for food that it intends to attack and eat its fellow comb jellies.

4. Deep-sea dragonfish

This fish is believed to be harmful because of its oversized teeth and hideous face. Instead of having a scale, its body is wrapped with slippery and slimy skin that looks like an eel.

Its length is about 6 inches long and they are preferable to swim in the parts of the ocean having no light, decreasing temperature, and at the depth of approximately 700 and 6,000 feet below the sea surface.

Moreover, their body is luminescent one where it provides a glow to help them in communicating with other fish and provide camouflage for both prey and possible predators.

A small fish possess skinny and bioluminescent bodies and shiny scales that contribute to its metallic appearance. Its bioluminescent bodies have the ability to alter its brightness that allowing them to counterilluminate its body to be able to camouflage.

The dim light that they can produce in itself is their protection against their predator. They are found below the sea surface at 5,000 feet deep that eventually contributes to their ruggedness look.

6. Dumbo Octopus


It is named after a Disney favorite Dumbo octopus can be found estimated at 9,800 meters below the sea in Marianas Trench.

Its length ranges from 8 to 12 inches and it is adorable to see them swimming by flapping their ears. However, they may be soothing to see but it is an undeniably lethal creature as they can swallow their prey in one big gulp.

7. Frilled Shark

Its name is attributed to its 6-7 frilled gills. Their body structure composes of a flattened head and a rounded body. Apart from that, this frilled shark also contains about 300 teeth that could possibly tear any animals that may go near them.

They extremely love to stay at the location 4,000 feet below the surface. Like any other sea creatures who used to live at the ocean’s bottom, when they pull up above their preferable depth, they tend to perish.

What has been discovered recently is made possible through the technologies that continuously advance through time.

With technologies, we have been given an opportunity to discover and explore a little, not just our pet animals or those that live above ground, but also what lives in the deepest part of the ocean. However, some mysteries behind the deepest ocean are yet to be discovered.

Surely, as time passes by, there will be a series of discoveries to come out. However, the progress may not be as fast as sending scientists to outer space as we know deep oceans are undesirable environments to explore gradually.

Marianas Trench as the deepest part of the ocean will remain a mystery to all until researchers and scientists can find new ways and strategies to investigate further the undiscovered deep sea.

Soon enough, the knowledge and understanding of what lies in the deep ocean will be a complete puzzle for the science community and for the people.

animals that live in the deepest part of the ocean

Animals that live in the deepest part of the ocean are known as abyssal creatures. These creatures have adapted to the extreme conditions of high pressure, low temperature, and complete darkness that characterize the abyssal zone. Some of the most well-known abyssal creatures include giant squid, anglerfish, and fangtooth fish.

Can anything live in the deepest part of the ocean?

Yes, there are organisms that can survive in the deepest part of the ocean, known as the hadal zone. These organisms have adapted to extreme pressure, cold temperatures, and darkness.

Some examples of hadal zone organisms include amphipods, snailfish, and giant isopods. Despite the harsh conditions, these organisms have found ways to thrive in one of the most extreme environments on Earth.

What fish lives in the deepest part of the ocean?

The fish that lives in the deepest part of the ocean is the Mariana snailfish. This fish is found in the Mariana Trench, the deepest part of the ocean, at depths of up to 8,000 meters. The Mariana snailfish has adapted to the extreme pressure and darkness of the deep ocean by having a soft, gelatinous body and large, sensitive eyes.

What lives in the deep deep ocean?

Deep sea creatures are organisms that live in the deepest parts of the ocean. These organisms are adapted to extreme conditions such as high water pressure, low temperatures, and lack of sunlight. Some examples of deep sea creatures include anglerfish, giant squid, and viperfish.
