Gerrhonotus

Gerrhonotus is a genus of anguid lizards that are commonly referred to as alligator lizards, due to a vague resemblance to an alligator. Most species are restricted to Mexico, but a few range into Guatemala or Texas, and G. rhombifer is from Costa Rica and Panama. Along with glass lizards (Ophisaurus) and many other lizards, alligator lizards have the ability to regrow their tail.
