Reptiles and Amphibians
Reptiles and amphibians are cold-blooded animals whose bodies take on the temperature of their surroundings. They may be seen basking in the sun on warm rocks that make up the mountain. Cool nights usually send them into burrows or crevices to keep warm.
Several species of snakes and lizards inhabit the monument. Amphibians are somewhat less numerous since there is no permanent water source in the park.

Lizards and other reptiles need to warm up in the sun. Visitors to Capulin Volcano often see lizards scurry into rock crevices when startled.
