But the axolotl is not the only member of the animal kingdom that can do this (Figure 1), as many invertebrates (animals without a spine) are masters of regeneration.

There is no need to wonder that many scientists are interested with this type of salamander.

In 1787, Francesco Clavigero wrote that, "the axolotl is wholesome to eat, and is of much the same taste with an eel.

Axolotls are very unique and interesting due to the regenerating process. Where's axolotl?

Facts about Axolotls 8: the mating season.

The axolotl is a Urodele amphibian, which includes all newts and salamanders. They often conduct research about axolotls. They are uncommon at pet stores because they require a cool temperature, but may be obtained from hobbyists and scientific supply houses. The axolotl (pronounced ACK-suh-LAH-tuhl) salamander has the rare trait of retaining its larval features throughout its adult life. Flatworms and hydra, for instance, can regrow their entire bodies from only a tiny piece of their original selves. Axolotls are closely related to waterdogs, the larval stage of the closely related Tiger salamanders Ambystoma tigrinum and Ambystoma mavortium. Axolotls are important research animals and fairly common exotic pets. Axolotls are used a lot in scientific research because they can regenerate most body parts, are easy to breed, and have large embryos. However, unlike the others that leave the water once they are sexually mature, the axolotl stays solely aquatic. A single axolotl needs at least a 10-gallon aquarium, filled (no exposed land, like for a frog), and supplied with a lid (because axolotls jump).

Axolotl tamales were a favorite, served whole with cornmeal. One such organism is …

These are common in much of North America and also sometimes become neotenic.
