Question

Why lizard is called a poikilothermic animal?

Answer 1

Answer:

Both reptiles and amphibians are poikilothermic, which means that they cannot regulate their own body temperatures internally as birds and mammals do.

Answer 2

Answer:

Reptiles are cold-blooded, or ectothermic, animals. This means that they cannot produce heat in their own bodies, and have to rely on their surroundings to keep warm. This is why most reptiles are found in hot or warm climates. Reptiles often bask in the sun to get warm.
