The Earth has existed for approximately 4.5 billion years. We don't know how many living things have survived during this vast period, and we don't know if we are the only intelligent life forms on Earth.
What existed on Earth in the past cannot be explored with our current technology. However, with the development of the Earth, we humans have also continuously discovered the prehistoric creatures that still live today.
1. Frilled Shark - 150 million years ago
The crossbreeding between sharks and eels is troubling. The frilled shark has lived for nearly 150 million years and is one of the top ten living prehistoric animals. Luckily, it’s right at the bottom of the ocean.
The frilled shark is a primitive shark and the only species of the frilled shark genus in the family Chondrichthyes, order Hexabranchidae. Because the gills are goneonges and their folds overlap, they are called frilled sharks.
2. Tadpole Shrimp - 220 million years ago to present
It may not sound too scary, but it has been alive for 220 million years. This thing can survive until now. I feel like it’s not something to underestimate. The tadpole shrimp is also called the three-eyed dinosaur shrimp. The tadpole shrimp has actually experienced several radiation and extinction events. But they still survived.
3. Coelacanth - 360 million years ago to present
The Coelacanth is a fish of the order Coelacanths, comprising the oldest branch of the submandibular phylum. The coelacanth species is thought to have gone extinct at the end of the Cretaceous period, at least 65 million years ago.
Most people think that this 360 million year old fish is permanently extinct. Only one sighting has been reportedin 1938...until the last 10 years when fishermen continued to spot them.
4. Elf shark (European shark) - 118 million years to present
European shark, also known as the European swordfish, European swordfish, also known as the goblin shark, it is the only species in the family Scyllidae and is a deep-sea shark. The characteristic feature of the shark's snout is that its snout protrudes forward to form a pointed process, longer than that of other sharks. It uses it to detect its prey. Its two jaws move forward to form a beak shape, and it can stretch suddenly. out to catch prey. Another characteristic is its translucent skin which allows blood to appear giving the body a pinkish tint.
This guy is a scary fish. Fortunately, prehistoric animals like goblin sharks and humans don't play together. They have themiment at the bottom of the Pacific Ocean, as they did 118 million years ago.
5. Ant Martialis Heureka - the last ancestor of ants
This ant originated 1.2 million years ago until its discovery in the Amazon jungle in 2008. It is the last common ancestor of all ants discovered so far. As the last ancestor of ants, it is admirable that it is still alive today.
There may be older creatures waiting to be discovered. For example, in the depths of the sea, the most mysterious and also difficult place for humans to explore, there may be even more peculiar life forms. The body is waiting to be discovered.
