In the history of the earth, there was a famous mass extinction event, which is Cretaceous -Paleogene extinction event . During this extinction incident, the non-bird dinosaurs were completely exterminated, and most of the animals and plants on the earth at that time were exterminated. There are many statements about the causes of extinction, such as asteroid impact theory , climate change theory, species struggle theory, continental drift theory, etc.
Nowadays, the dinosaur, the ancient beast , only remains of the dinosaur, scattered all over the world.
However, there is a magical animal in the world that is named "dinosaur". Why is this? What is its connection with dinosaurs?


"I have horns on my head and a tail behind me." This song is singing about the little green dragon, but hexagonal dinosaur also meets this characteristic~

hexagonal dinosaur, scientific name is Mexican aphrodisiac (Axolotl) , belongs to the salamander . It has six horns like dragons on its head, which are actually the gills it uses to breathe, so it is named "hexagonal dinosaur".
It has a smooth body and feels like loach . It has an adult body length of about 25-30 cm. It has bean-like eyes. The artificially reproduced body color patterns are diverse. In my country, the common individuals include primary colors, whitening black eyes, whitening red eyes, gold and other individuals. It swam and its tail swung slowly, looking ugly and cute.

However, although it doesn't seem to have any combat power and it's easy to underestimate it, it's a complete water tank.
Hexagonal dinosaur searches for food through smell, and will absorb it on the food and use the vacuum power in the stomach to absorb the food. Therefore, if it is mixed with other water organisms, it goes without saying that the small fish and shrimps of foreign races do not look at the face of the fish, and it is normal to catch the mouth directly.
Even if the brothers and sisters of this clan are in conflict, they will fight and bite.
Therefore, if you want to raise hexagonal dinosaurs artificially, remember not to mix them with fish, shrimp, turtles, etc. Even for the same tribe, it is not advisable to raise the body shapes together. There have been examples of the big dull aphrodisiac swallowing the little dull aphrodisiac.

hexaceous dinosaur is the only larval mature amphibian in the salamander family . What does
mean? It is lifelong juvenile state, which is called "juvenile state continuation" (neoteny) . They remain juvenile from birth to sexual maturity after 12 months. Basically, what I looked like when I was a child did not change much when I grew up. There may be some subtle differences as you get older, but there will be no major changes in the whole body.

Generally speaking, hexagonal dinosaurs that maintain larval sexual maturity can generally live for 10-15 years, and most can live for 25 years.
Under natural state, hexagonal dinosaurs will not evolve into salamanders themselves unless they are manually intervened, such as adding some thyroid hormone during feeding, or increasing the iodine ion content in the water.
However, this method of artificial intervention in the natural growth of organisms comes at the cost of life span, so that they can only live for four or five years.

The most common gecko in our daily life is the gecko. When we were young, we read the story of " Little Gecko Borrowing Tail " in textbooks - the little gecko's tail was bitten by a snake, so we went out to borrow the tail, but unfortunately we borrowed it all. When it borrowed a circle and returned home, it found that its tail had grown.
The regeneration ability of hexagonal dinosaurs is even more amazing than that of geckos. Its regeneration includes various organs and tissues such as eyes, spinal cord, heart, intestines, upper and lower jaws, and there will be no scars left in the newly grown places. Therefore, when it encounters natural enemies, it will give up certain parts in time like a gecko in exchange for the chance to escape.

Why does it have such magical regeneration ability?
This is because there is an immune cell called " macrophage " in its body. When it is injured, this cell will divide into the surrounding cells, and regenerate a complete part according to the needs. This process is like a small tree sprouting, and it can sprout more than once, and it will not affect its normal activity. People are naturally curious about the powerful genome like
. However, after research and research, there are many speculations, but the conclusion is still undecided. With the deepening of the study of the regeneration process and mechanism of the newt brain, it is believed that it can provide important guidance for the repair of human nervous system damage or degenerative diseases.
