EXOTHERMIC ANIMALS

• Obtienen el calor del medio externo

• Tienen distintos mecanismo para estabilizar su temperatura.

• Regulan temperatura por medio del comportamiento. Ej. Lagartos

• Fish, amphibians, reptiles

ENDOTHERMIC ANIMALS

• Capaces producir calor por si mismos.

• No dependen del medio externo

• Tienen un mecanismo interno de regulación de la temperatura corporal

• Birds, mammals
