Question

If a reptile temperature gets to low what does it need to do

Answer 1

Reptiles require external heat to thermoregulate.  If a reptile's temperature gets too low, it will need to find a source of heat to raise its body temperature.  In the wild, most reptiles do this by basking in the sun.  In captivity, heat lights, heating pad, and other heat sources are provided to allow them to thermoregulate.
