About Salamanders ...

The axolotl ( Ambystoma mexicanum ) is a large salamander native to Lake Xochimilco, Mexico. It belongs to the group of salamanders known as mole salamanders. Other members of this group include the axolotl's close relative, the tiger salamander ( Ambystoma tigrinum ), and the spotted salamander ( Ambystoma maculatum ).
