There Are 500 Million Years Old, These 6 Ancient Sea Animals Are Still Living Until Now

Do you know what creatures belong to ancient sea animals?

Ancient sea animals means sea animals that have lived since prehistoric times, tens or even hundreds of years ago, friends.

Among ancient sea animals that once ruled the ocean, there are ancient sea animals that are still alive today, lo.

Let's find out some ancient sea animals that are still alive today!

Pygmy Right Whale (23 Million Years)

Pygmy right whales have been on Earth since 23 million years ago.

Pygmy right whale is one of the smallest species of whale. The habitat is the open ocean and is believed to exist in the cold waters of the southern hemisphere.

At present, the pygmy right whale species is the rarest, lo.

He was so mysterious that scientists had not yet succeeded in discovering the type of food, breeding process, and behavior of these whales, friends.

This whale is increasingly threatened because of the increasingly hot sea water conditions, friends.

Frilled Sharks (80 Million Years)

This shark lives in a deep ocean, friends.

Although the appearance of this frayed shark is a bit creepy, it is known to have a chubby, frayed cheek. This is because he has six gills.

Oh yes, even though he is a shark family, frayed sharks also resemble snakes.

This fish is known to have sharp teeth. The number of teeth there are 300 teeth, lo.

It can also lurk and ambush prey that is half its size and then immediately swallow prey.

Lamprey Fish (360 Million Years)

Wow, with this age, it means that the lamprey fish species have passed four times of mass extinction.

At that time, this fish can be found in the Atlantic Ocean and become a species of migrants on the Great Lake. They can live in fresh water and salt water, friends.

This fish is similar to eel but has no bones like eel. It only has a cartilaginous skeleton with a single tail fin.

This creature is like the creature seen in a science fiction movie, here.

He has a big mouth with jagged teeth and a sharp tongue.

This lamprey fish gets its nutrition by absorbing the blood of its prey.

Horseshoe Crab (450 Million Years)

Older than a lamprey, there is a horseshoe crab that has 450 million years of life on Earth.

In fact it means that he also lived during the extinction of the dinosaurs and five mass extinctions.

Despite its name, crab, actually this ancient sea animal is more closely related to the scorpion.

Oh yes, the body shape of a horseshoe crab looks scary but actually it is harmless, lo.

In fact, the blue blood in a horseshoe crab is used to identify toxic bacteria.

Unfortunately, these crabs have decreased population due to climate change, habitat loss, and overfishing.

Nautilus (500 Million Years)

This is, ancient sea animals that have existed since 500 million years ago.

Nautilus is a mollusk that existed before the continents of our Earth were separated, friends.

Initially there are 1,000 species of Nautilus, lo. Now only a few species of Nautilus remain in the Pacific Ocean and the Indian Ocean.

They eat fish, crabs and lobsters, friends. This animal has tentacles and its mouth is shaped like a beak.

Nautilus can use his mouth to disassemble the hard shell and hyponomoe tube to regulate the amount of water and air in the shell.

This mollusk has great buoyancy and inspires submarines, lo.

Today, these animals also experience a decline in population due to overharvest due to beautiful shells. Plus, the process of breeding of the nautilus is slow, friends.

So the Deepest Point on Earth, What's in the Mariana Trench?

The highest point of the world is the summit of Mount Everest in the Himalayan Mountains, friends.

What about the lowest point in the world, huh? The deepest part of the Earth is the Mariana Trench in the Pacific Ocean, friends.

So deep, to the point that there is no light in the Mariana Trench, lo.

Wow, about there is no life huh, there? Let's find out what can be found inside the Mariana Trench, huh?

Weird creatures on the seabed

According to scientist Douglas Bartlett who has carried out deep sea expeditions, the most visible are sediments of gray-green sediment.

But, if there is food placed there, living things will begin to appear.

Yep, apparently at the deepest point on Earth there is also life!

However, living things that live in the deep sea are usually unique and even strange creatures. Anything?

Amphipod

One unique creature on the seabed is amphipod, which is a crustacean animal.

Although the body is similar to shrimp and lobster, amphipod can grow as long as 30 centimeters, lo.

Amphipod has an exoskeleton made of potassium carbonate. Potassium carbonate is usually not found at a depth of 10,000 meters below sea level.

The reason is that, under a depth of 4,500 meters, the pressure in the water is getting higher and the temperature is very low. So that calcium carbonate can dissolve in water.

Then, how can amphipod live there?

Amphipod has a secret shield, lo, which is an aluminum layer made on its body.

Aluminum is sourced from aluminum on the seabed.

Apparently, amphipod needed the shield to protect itself from other creatures at the deep sea point.

Mariana Snailfish

In the darkness of the Mariana Trench, there are creatures that lurk amphipod, the Mariana snailfish.

Mariana snailfish is a fish found living in the deepest point.

Scientists have seen it swim to depths of 8,000 meters below sea level.

Even though it looks like a normal fish, the Mariana snailfish has flexible bones. According to scientists, the flexible bones helped him survive with such intense pressure in the deepest trenches.

This Mariana snailfish is blind, friends. In addition, in the part of the sea where he lives there is also no light that can help him see.

The fish also has transparent skin so that its organs can be seen from the outside.

Although not large in size, the Mariana snailfish is a first-rate predator in the deep sea.

One-cell organisms in the Mariana Trench

In addition to the Mariana snailfish, there are also other strange creatures, namely xenophyophore.

Xenophyophore is a single cell organism that looks like an amoeba, but has a large size.

The creature consists of only one cell but its size reaches 10 centimeters. It is the largest single cell organism on Earth.

Sea Cucumber "Sea Pigs"

The animal, called the sea pig, is actually a transparent sea cucumber crawling on the seabed.

Its body is shaped like an insect and its legs are like tentacles, friends.

Plastic waste

Yep, even though far from humans on land, plastic waste is also found in the Mariana Trench, the deepest point in the world.

In 1998, scientists detected a plastic bag at a depth of 10,898 meters below sea level. Then in 2019, scientists said there was more plastic debris at a deeper point.

In fact, microplastics are also found in the stomach of the amphipod in Challenger Deep, the deepest point of the Mariana Trench.

Sad, huh? This means that humans have dumped too much garbage that ends up in the sea to pollute the deepest places on Earth.

C'mon, friends, we reduce the use of disposable items so they don't become rubbish and can end up in the sea.

Sad, There is Plastic in the Stomachs of the Residents of the Mariana Trench, Even though the Species Are Newly Found

Have you heard about the Mariana Trench, haven't you?

The Mariana Trench is the trench where the world's deepest point is.

But did you know? Even deep in the deepest places, scientists found plastic waste produced by humans on land.

Sadly, recently there was even a new species found in the Mariana Trench, but in his stomach there was plastic.

Plastic Trash in the Stomach of New Species Found in the Mariana Trench

The team of researchers from Newcastle University in England discovered a new species of amphipod, which is a crustacean animal.

The new amphipod species was found at a depth of 6,000 meters below sea level, in the Mariana Trench.

Unfortunately, when researched, scientists found that in the stomach of the new species of amphipod there was plastic debris.

The size of the plastic debris is so small, or commonly called microplastic.

The researchers examined the type of plastic and found that the plastic in the stomach of the amphipod was plastic type PET (polyethylene terephthalate).

PET plastic is usually used as a beverage and food packaging. PET plastic is made as a disposable plastic, but can be recycled.

Unfortunately, the plastic was actually wasted and caused global pollution, even to a remote place and not inhabited by humans.

Newly Discovered Species A Reminder of Humans

Researcher Alan Jamieson from the University of Newcastle in England said that the new species discovered had been contaminated, so researchers could no longer understand the species in its natural environment which was not contaminated.

Seeing the state of the amphipod species that carries plastic in its stomach, scientists named it Eurythenes plasticus.

The naming was deliberately made to remind the world population that the impact of pollution in the sea is very dangerous.

Garbage that reaches the ocean not only makes the environment dirty, but also disrupts the life of marine life.

The discovery of species that have been contaminated with garbage is increasingly explaining that the problem of plastic waste is very big impact.

This is because human activities can affect the lives of living things living in remote places.

Plastic in the Ocean

According to 2015 research, there are at least 8 million tons of plastic entering the ocean every year.

The plastic that enters the sea breaks down into smaller parts and eventually becomes microplastic, which is eaten by animals, even animals that live in the Mariana Trench.

Plastic that does not decompose in the digestion of animals can cause blockages, so there is no room for food anymore and actually absorb harmful compounds.

Poor, right, friends?

Eurythenes plasticus is not the only animal whose life is disrupted by plastic debris reaching the ocean.

Therefore, in order to preserve our Earth for all living things, we together reduce the use of disposable plastics and recycle as much as possible the recycled material, let's!
