Just the opposite. Mammals are endothermic, which means warm-blooded: they generate their own body heat. It allows them to move around at night and in the cold, but at the expense of needing far more food to survive.
Exothermic animals, such as lizards and insects, rely on the sun's warmth or the ambient heat to provide the energy they need to be active. The advantage is that they don't need to eat as much; the big disadvantage is that they must slow or shut down as the temperature drops.
It may help to remember that exo- means from outside, while -thermic means having to do with temperature. (Think of the exterior of a house, and its thermostat.) So exothermic literally means getting heat from an outside source, which mammals don't do.
What else can I help you with?
Are all insect ectotherms?
Yes. As a rule of thumb; all animals are ectotherms except for mammals and birds.
Are dolphins ectotherms?
No, a dolphin is a mammal and all mammals are endotherms.
Are toy poodles endotherms or ectotherms?
All mammals are endothermic (warm blooded). Ectotherms are cold blooded animals like snakes and lizards.
Are mammals endothermic or ectothermic?
ectotherms because how they react is simaler to their functions but reptiles are enthoderms
What classes of vertebrates are endotherms?
birds mammals fish(also ectotherms)
Is a squid a endothermic or ectothermic?
A squid is ectotherm. Any animal except birds and mammals are ectotherms
Are Mammals ectotherms?
NO. Mammals are endothermic, and give off heat. endothermic creatures are also known commonly as 'warmblooded'.
Are horses endotherms or ectotherms?
Endothermic.
What is the opposite of ectotherms?
The opposite of ectothermic is endothermic. Ectotherms maintain their body temperature by behavior rather than metabolism. Endotherms maintain a warm, consistent body temperature with the use of energy.
Can you list ectotherms?
Reptiles (Lizards and Snakes) are ectotherms Amphibians are ectotherms
Is a tiger a warmblooed?
No. They have lots of penis juice in there butt which channels to the brain causing the blood in the body to mate with itself causing... LESBIANS!
How are ectotherms and poikilotherm the same?
Ectotherms and poikilotherms are similar in that both rely on external environmental temperatures to regulate their body heat. Ectotherms, which include reptiles, amphibians, and many fish, do not generate significant internal heat and depend on their surroundings to maintain their body temperature. Poikilotherms, on the other hand, are organisms whose body temperature fluctuates with the ambient environment, which can include both ectotherms and some endotherms that can have variable body temperatures under certain conditions. Essentially, all ectotherms are poikilotherms, but not all poikilotherms are necessarily ectotherms.
