The axolotl also known as a Mexican salamander (Ambystoma mexicanum) or a Mexican walking fish, is a neotenic salamander, closely related to the tiger salamander. Although the axolotl is colloquially known as a "walking fish", it is not a fish, but an amphibian.
The species originates from numerous lakes, such as Lake Xochimilco underlying Mexico City.
Axolotls look very interesting. They have external gills that look like dark red feathers, four legs (hence the walking), a long tail, and a large flat head. The do indeed have a great deal of character.
Axolotls come in numerous colours but there are three main shades. These include: dark, gold and albino.
Axolotls have long fascinated scientists for their ability to regenerate lost body parts and for their rare trait of neoteny, which means they retain larval features throughout life.
Axolotls usually live about 15 years if kept in good conditions. May live even longer, some are reported to have lived up to 25 years.
