Lava lizards are the most abundant reptile in the Galapagos Islands. Seven different species of lava lizards occur here and they play an important role in controlling insect populations in the Islands. The male and female lava lizards are morphologically distinct. The males are larger and striped whereas the females are smaller and have a orangey-red throat. When a lava lizard is threatened by a predator or something has grabbed their tail, they have the ability to self-amputate it. Lava lizards are often seen with a new tail growing. They are often seen doing push-ups; it’s not for exercise but to attract a mate.
