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

• Tienen un mecanismo interno de regulación de la temperatura corporal
• Birds, mammals
