Their daily routine revolves around leisurely eating, basking in the sun, and resting for 16 hours a day. Also, they have a key role in the Archipelago’s ecosystem.

  5. Defensive Mechanism:

    Galapagos lava lizards possess effective defense mechanisms. In the face of a predator attack, they rely on their camouflage abilities and swiftly seek refuge in crevasses or under rocks. Additionally, they have the remarkable ability to detach their tails from their bodies, which can distract or confuse predators. The detached tail regenerates within a few weeks.
