Fish & Marine

Reptiles are of the class Reptilia. They lay eggs and their skin is covered with scales. They are often referred to as "cold-blooded" because unlike "warm blooded" mammals they cannot regulate their own body temperature internally. Instead their body temperature is determined by the ambient temperature of their environment.
