Who is the ancestor of the baby fish known as the giant panda in the water ?

I wonder if you have ever seen an animal called a giant salamander? Perhaps this creature will be clearer to everyone in another way, that is, "baby fish". Is it because this fish is so cute?

In fact, the name of the baby fish is not because it looks cute, but because the cry of this animal is very similar to the cry of a child, so it is called "baby fish". Moreover, the salamander is also the most precious amphibian that still exists in the world, and it is also a second-class wild protected species in our country. So as a protected animal, do you know who its ancestors were?

In fact, as early as 350 million years ago, there was a creature called "baby fish", which is a little earlier than the origin and development of our human beings, and it can be said that the baby fish is a creature of the same era as the dinosaurs. It is also of great significance in the evolutionary history of living things, and some people even call it the "giant panda in the water", which shows the importance of the baby fish.

Dinosaurs are considered to be extremely important animals, but in fact, at that time, there were predators at the top of the food chain that threatened the existence of dinosaurs. One of them is the overlord salamander. This animal is not a good species, it is very aggressive, so that dinosaurs that humans fear do not dare to approach them easily.

And this creature is the ancestor of the baby fish, but after a long evolutionary process, it has lost such a strong deterrent at the beginning. The salamander has hundreds of sharp teeth in its mouth, and the creature is between 3 meters long, but it is unknown why such a powerful creature lost its luster during the mass extinction of the species.

There is a theory that the extinction of the overlord salamander was to make way for the existence of dinosaurs, as if humans would be born after the extinction of dinosaurs. The overlord who once dominated the world has now degenerated into a rare animal that needs to be protected by humans, but didn't the dinosaur also become a bird animal in the process of evolution? So these are the final outcomes of natural selection.

China's salamander is mainly distributed in Zhangjiajie, because there is a sandstone peak forest landform formed in the Devonian period more than 300 million years ago in Zhangjiajie, which is the main origin of salamander, and has a unique ecological environment for salamander to reproduce. After reading the above, I don't know if it gives you a new understanding of the ancestors of the baby fish? Differing opinions are welcome.

There is an animal overlord salamander that is considered the ancestor of the salamander. The creature is between 3 meters long and has hundreds of sharp teeth in its mouth. Vicious dinosaurs are afraid of it.

The baby fish is a particularly precious amphibian, and the reason for its name is not because it looks cute, but because its cry is similar to that of a child. They actually appeared many years before humans, so according to the literature, its ancestors should be dinosaurs.

Sturgeon. This is a very ancient fish, which originated 150 million years ago, and its life cycle is very long, the longest can reach 40 years.

Baby fish used to be eaten every day.

Known as the giant panda in the water, the salamander's ancestors are: the overlord salamander, a creature that is the ancestor of the salamander.

It should be dinosaurs, dinosaurs can be regarded as the earliest creatures that appeared, so many creatures evolved through dinosaurs. The living habits of amphibian baby fish and dinosaurs are still very similar.

Sturgeon. It is an ancient fish with a very long history and a relatively long lifespan, but it is difficult to see them nowadays.
