An experiment was done in which two ajolotesone black and the other ajolofe, were cut in half laterally and sewn together. The size difference is mostly explained by a large fraction of repetitive sequencesbut such repeated elements also contribute to increased median intron sizes 22, bp which are 13, 16 and 25 times that observed in human 1, bpmouse 1, bp and Tibetan frog bprespectively.

Surveys in, and found ajolohe, 1, and axolotls per square kilometer in its Lake Xochimilco habitat, respectively. One attractive feature for research is the large and easily manipulated embryowhich allows viewing of the full development of a vertebrate.
They are about 10 inches long and have three pairs of gills growing hairdo-like back out of their heads. A neotenic amphibian, it retains features from its larval stage during adulthood like those people who never seem to grow up.

These new fish have been eating the axolotls’ young, as well as its primary source of food. For conservation purposes, plastic netting has been used in the lake in Xochimilco to isolate them in areas for reproduction.

Instead of developing lungs and taking to the land, adults remain aquatic and gilled. Those amphibians were the inspiration for one of the most famous pokemons: Their habitat is like that of most neotenic species—a high altitude body of water surrounded by a risky terrestrial environment.
For other uses, see Axolotl disambiguation. The axolotl is therefore used as a model for the development of limbs in vertebrates.
