Beings of the class Reptilia are abundant and more diverse in hot climate regions and they are rare in intensely cold regions like close to the earth poles. This is explained because these animals are heterothermic, i.e., they have “cold blood” and they need an external heat source to warm their bodies.
The heterothermic feature also explains why reptiles are more active during the day, a period when they can use the sun heat to warm their bodies.
