basking

The most common type of burns seen in captive reptiles are thermal and are usually attributed to an abnormally hot heat source, one from which the animal cannot escape. Captive reptiles should always be provided a basking spot, but the enclosure should be large enough that the reptile may retreat to cooler areas if and when the radiating heat becomes too intense. In the wild, thermal burns may be encountered when the reptile has survived a grass or forest fire.
