The Mexican axolotl, commonly known as the hexagonal dinosaur, is an aquatic amphibian and a species endemic to Mexico. The natural environment can only live in muddy waterways and lakes. It is famous for its unique appearance and larval sexual maturity. In other words, even after sexual maturity, it will not undergo changes to adapt to land, and still maintain its aquatic juvenile form. Although it is bred as a pet in the world (especially in North America and other places), its native habitat has been extensively developed, causing sandification of the lake bottom, destroying the silt environment of the lake bottom, and causing functional extinction. The living area is no more than 10 square kilometers. It is rated as a critically endangered species in the IUCN Red List.

The Mexican axolotl has the ability to regenerate fragments. Average life span: 10-15 years. Wild individuals are only distributed in the Chalco and Xochimilco lakes in Mexico. They belong to the Amphibians and Caucus. The Mexican axolotl is a well-known "larval mature" species of amphibians (from birth to sexual maturity and spawning, all are larval forms). The Mexican axolotl also has an extraordinary ability to regenerate. After losing a leg, it will quickly grow a new one. It can even regenerate very complex body parts, including parts of the brain and spinal cord, so scientists are very interested in it.

The larvae of the Mexican axolotl live in water throughout their lives and lay eggs. They have been kept for more than a hundred years, and they are mainly used as living organisms for endocrine experiments. Therefore, the research on their breeding and reproduction has been almost completely established. Nowadays, they can hardly be seen in the wild. They can only be seen in some aquariums. . At present, domestic artificial breeding is quite mature, and breeders need to be careful not to use sand and gravel in the breeding environment, otherwise the blunt-mouthed newt will die from eating sand and gravel by mistake.

The Mexican axolotl is an omnivorous animal. Main food: algae, worms, shellless insects or small fish and a small amount of other fish feces. For feeding, you can feed a variety of easy-to-find foods, including: chicken, various freshwater fish, freshwater shrimp, and for convenience, you can also feed frozen or fresh bloodworms, earthworms, and waxworms. Or other high-protein, low-fat foods without hard shells, high-starch foods, and processed products that people eat, such as ham sausage and cooked meat, must not be fed. The juvenile axolotl can be fed with daphnia, brine shrimp, or other freshwater microalgae until it grows up to eat larger foods.
