The oldest 12 species of animals on Earth


There are millions of animal species on our planet, but to date science has only discovered a small part of them. Also, there are plenty of missing species, some recently, others before their man roam the Earth. But what are the animals that precede the species and who still live?

12. Goblin Shark - Age - 118 million years

Goblin shark is an abseal species of shark and is one of the most scary animals in the aquatic world. Fortunately for us, Goblin sharks live in the ocean floor and rarely dare to leave their habitat. It is for this reason that people have seen this shark very few times, although they have been rewarding over 100 million years. In 2007, a Goblin shark was captured for the first time in Japan, but died in a few days. However, scientists have been able to examine the specimen and have learned more about this living fossil.

11. "Ants on Mars" - the age - 120 million years

The only terrestrial creature in this top, "Ant's Mars" is probably one of the first descendants of ants today. Martialis heureka was not only the discovery of a new ant species, but also a totally new genus and a new subfamily, a primitive, prehistoric, one that existed 120 million years ago at the beginning of ants evolution. Until now, scientists have discovered a single copy of this species in the remains of vegetation dead on the soil of the Amazon forest in the Empresa Brasileira area of ​​Pesquisa Agropecuaria in Brazil.

10. Collar shark - age - 150 million years

Guler shark is the oldest shark species that still exists. He also had the honor of being among the most "badass" creatures, published some time ago (link). Due to the advanced age, collar shark is less evolved than its "modern" relatives, his body looking like a combination of shark and print. Like the Goblin Shark, the collar shark is an abisal species living on the bottom of the ocean, and although they are sometimes caught by mistake, they are rarely seen by humans.

9. Stuur - age - 200 million years

Sturion is actually a generic term for several species that have existed for the last 200 million years (moron, nisetru, pastruga, cega, sip, visa, monk, etc.). But despite age and resistance, almost all sturgeon species are threatened with extinction because of its predominant predominant man: the man. The sturgeons are caught for their eggs, from which the caviar is made. Good news is that the sturgeon is capable of depositing millions of eggs. Bad news is that people still eat it.

8. Hazel shrimp - age - 200 million years

The oldest shrimp species. It has escaped untold evolution and has not changed at all in the last 200 million years. We know this because the fossils found by archaeologists look identical to the horseshoe shrimp that swim in the world's awards today.
         

7. Mistletoe shrimp - age - 220 million years

Even though this species has been roaming the land for more than 200 million years, it is classified as endangered. Will it conclude its existence before the current generation of people? Maybe not. In 2010, scientists have discovered a unique trait that gives these creatures a chance to survive. It seems that their eggs can stay dry and latent for very long periods of time, and can "invigorate" when they are rehydrated.

6. Lampetra - age - 360 million years

Lampetra, also known as petromizon, chiscar, hyssina or sugary, is a parasite-like parasite. This baby has a circular mouth with dozens of sharp teeth used to pierce fish scales to suck their blood. This sea vampire swims in the Earth's waters since the Paleozoic. In 2006, the scientists studied a 360-million-year-old fossil and found that it was basically the same as today's lamps.

5. Ceiling - Age - 360 million years

The blade was considered a missing animal. Missed for millions of years. That until 1938, when I found one. Since then scientists have studied this fish, extremely rarely and extinctly, with great interest because it is very similar to the fish from which the first terrestrial vertebrates evolved. It's one of the few animal species, and the only one that still exists, which can help us understand how it evolved ... well, just about any animal.

4. Horseshoe crab - age - 445 million years

Horseshoe crabs are among the most well-known species of "living fossils," which have remained practically unchanged for an amazing 445 million years. In 2008, Canadian scientists discovered a fossil at that time, although we already knew that this species is one of the oldest on earth. But the novelty was that this fossil has proven that the species is 100 years older than previously thought.

3. Nautilus - age - 500 million years

Half a million years. So long the futile lives on Earth, surviving all the extinctions that reset life on earth along the course of evolution. However, this old cephalopod is threatened with extinction. Why? Thanks to man. It looks like we really like spiral coils and we use them for decoration. We "excessive" van, so that in places where hundreds or thousands a day are caught, now only one or two get caught.

2. Medusa - age - 505 million years

As we get to the end of the top, we notice that the animals are becoming more primitive. That's because we're talking about a period in the history of evolution in which the terrestrial animals did not exist at all. But jellyfish existed, even over half a million years ago. In 2007, researchers at the University of Kansas found new jellyfosses, 505 million years old, 200 million years younger than we previously knew. So there is no possibility of new fossils that surprise us again with their longevity.

1. Spongers - Age - 760 million years

We are not clear what is the real age of sponges, but we know they are old enough to be considered the oldest creatures on Earth, outside of microorganisms. The oldest fossil of a sponge has been discovered last year and dates back 760 million years ago. It struck 25 million years ago the record of another fossil discovered in 2009. That makes us think we will find fossils even older, but one thing is certain: finding other species older than sponges is unlikely because these simple organisms seem to be the ancestors of more complicated forms of life, including the first multicellular animals.
