Endotherms use internally generated heat to maintain body temperature. Their body temperature tends to stay steady regardless of environment. Ectotherms depend mainly on external heat sources, and their body temperature changes with the temperature of the environment.

What do scientists call animals that make their own body heat?
Mammals and birds have a body temperature that stays about the same no matter what the temperature of their environment is. Mammals and birds are called endotherms. An endotherm is an animal that can control its internal body temperature.
What animals can generate internal heat?
All mammals and birds are capable of generating this internal heat and are classed as homoiotherms (ho-MOY-ah-therms), or warm-blooded animals. Normal temperatures for mammals range from 97° F to 104° F. Most birds have a normal temperature between 106° F and 109° F.
What is the meaning of Ectotherms?
ectotherm, any so-called cold-blooded animal—that is, any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface. The ectotherms include the fishes, amphibians, reptiles, and invertebrates.
Why can't reptiles make their own heat?
Reptiles need to thermoregulate because they cannot maintain their body temperature by producing metabolic heat. They rely on external conditions to regulate the temperature of their bodies. ... Mammals and birds have to eat frequently as they rely on metabolic heat to maintain their optimal body temperature.
Do snakes produce body heat?
Snakes and other ectotherms are cold-blooded animals that lack the ability to generate body heat internally. Also known as poikilotherms, these animals must rely entirely on external sources to regulate their body temperature, both to stay warm and to avoid becoming overheated.
How do animals generate heat?
Mammals generate heat mainly by keeping their metabolic rate high. The cells of mammals have many more mitochondria than the cells of other animals. The extra mitochondria generate enough energy to keep the rate of metabolism high. Mammals can also generate little bursts of heat by shivering.
What do warm-blooded animals do to make their body heat?
Endothermy refers to the process by which various animals control their body temperature through internal means like burning fat, shivering, and panting. ... Most warm-blooded animals use a combination of these two mechanisms to maintain constant body temperature.
Whats it mean to be cold-blooded?
Definition of cold-blooded
1a : done or acting without consideration, compunction, or clemency cold-blooded murder. b : matter-of-fact, emotionless a cold-blooded assessment. 2 : having cold blood specifically : having a body temperature not internally regulated but approximating that of the environment.
Are fish cold-blooded?
Like reptiles and amphibians, fish are cold-blooded poikilothermous vertebrates —meaning they get their body temperature from the surrounding water. ... Temperature also affects metabolism and metabolic processes occur quicker in warmer water.
Which animal is not cold-blooded?
When I was a kid, I was taught that the animal kingdom could be divided into two groups. Warm-blooded animals, such as mammals and birds, were able to maintain their body temperature regardless of the surroundings. Cold-blooded animals, such as reptiles, amphibians, insects, arachnids and fish, were not.
Are fish warm-blooded?
“Scientists have long known that not all fish are cold-blooded. Some have evolved the ability to warm parts of their bodies so that they can stay warmer than the water around them, but it has remained unclear what advantages this ability provided.
Are whales warm-blooded?
Whales are warm-blooded mammals that can survive in water temperatures as frigid as the low 40s F. How do they manage to stay warm, even in the ice-cold waters of the Atlantic? By wearing a thick layer of fat, called blubber, just beneath the skin.
Do lizards heat?
Temperature Regulation in Ectotherms
One strategy snakes and lizards use to acquire heat is sunning. They find a sunny spot to bask in and absorb heat from the sun. Warm rocks or other surfaces also provide heat. They cool down by burrowing, exposing themselves to the wind or finding shade.
Are lizards warm blooded?
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. ... Reptiles often bask in the sun to get warm.
Can reptiles produce body heat?
Most of their body heat is generated by their own metabolisms. Ectothermic animals include reptiles and insects. They absorb most of their body heat from the surroundings.
Is Frog warm blooded?
Like other amphibians, frogs and toads are cold-blooded. This means their body temperatures change to match the temperatures of their environment. When winter comes around, frogs and toads go into a state of hibernation.
