Why Do Reptiles and Amphibians Need Heat?

{ 2:30 PM, 28/6/2006 } { Posted in Frequently Asked Questions } { 0 comments } { Link }
Reptiles and amphibians are said to be "cold blooded". What this means is that these animals draw their body heat from the environment and regulate their preferred temperature through behaviour. To increase body temperature they will bask in direct sunlight or on a heated surface such as a rock. To decrease it they can retreat to the shade, climb a shrub or tree, or enter a burrow or water. Housing should therefore provide a thermal gradient with an appropriate range of temperature that is monitored using thermometers inside the cage. This normally involves a 'hot spot' for basking, usually at one end of the cage, and the opportunity to move well away from this to cool off. There must be a physical barrier between the animal and the basking lamp to avoid burns. Water must be provided.
