There are many natural species in this world, of course, there must be differences in appearance. We all know that creatures hundreds of millions of years ago generally look more frightening, but there are still some creatures that maintain their appearance hundreds of millions of years ago. It really makes people feel that the world is so big, there is no wonder!
So this is the first one, of course, is our frilled shark. Just looking at this appearance, green eyes, and exposed sharp teeth, it makes people feel like a fierce character. It also has another name, called the pseudo-eel. Don't look at it scary, it is the most primitive shark species among sharks, known as "living fossils". Of course, those who can bear this title must have lived a long time. Of course, this event makes people feel that it is too long to measure, and the survival time of 380 million years makes people feel that this creature is even more mysterious. This look can only be seen 380 million years ago, but the frilled shark has maintained this look to this day.
Then the second kind makes people feel much more cordial, mantis shrimp, is also the old ancestor of biology, stopped its own evolution 400 million years ago.
Maintaining their attractive appearance to the present, Pippi shrimp we walk ~ marine shrimp, nutritional value is also very high, in the world distribution range is also extremely wide. I believe that this is also a "living fossil" that everyone is most familiar with, after all, it has been a mess of fire recently.
Then the next one, I'm sure everyone is not very familiar with it. The purple frog, also known as the West Ghats nose frog, is a living fossil in nature.
Purple frogs generally only live underground, and only appear on land during the rainy season, other times, of course, people can't find it. Look at its face that is not quite the same as the frogs today, which has not changed again 100 million years ago.
This cute guy is one of the most primitive mammals, a mammal that has not evolved completely, and of course there are few and pitiful species. Platypus appeared in Australia 25 million years ago, but since its appearance, it has not completed its own evolution, perhaps it is already relatively satisfied with itself.
At first glance, everyone must have thought that this creature was here to be funny, and George Shaw in the late 18th century thought the same thing when he received his specimens.
Unlike our ordinary ants, these ants are called Martian ants. This more alternative name is because it is not easy to come by, and its difficulty is almost like a creature from Mars, so it is named Martian ant.
The ancestors of Martian ants have always lived underground, evolving to surface activity 120 million years ago, and have not evolved further.
