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.
