The strange but also sweet face of the axolotl is swimming into more homes. This critter is a type of salamander native to Mexico. Axolotls prefer to have a large, cool tank with a gravel bottom all to themselves. If owners are attentive to their pet's water quality and diet, these animals can live 10–15 years. It helps that they have amazing regenerative abilities. Axolotls are able to heal rapidly and even regrow limbs.
