Which animal groups are endothermic?

Only birds and mammals are extant universally endothermic groups of animals. Certain lamnid sharks, tuna and billfishes are also endothermic. In common parlance, endotherms are characterized as "warm-blooded".

What animals are endothermic?

People, polar bears, penguins, and prairie dogs, like most other birds and mammals, are endotherms. Iguanas and rattlesnakes, like most other reptiles—along with most fishes, amphibians, and invertebrates—are ectotherms. Endotherms generate most of the heat they need internally.

Which of the following groups include endothermic animals?

Most of the mammals and bird species are warm-blooded animals. The whale is a mammal and pigeons and bats are birds. Thus, they are endothermic animals. Hence, option B is the correct answer.

Are amphibians exo or endothermic?

Both amphibians and reptiles are ectotherms, meaning that they derive heat from the environment, rather than producing it internally. To say that they are cold-blooded is imprecise since they, like endothermic vertebrates, need to keep warm in order to remain active.

Are marine animals endothermic?

Whales, dolphins, seals and other marine mammals can generate their own heat and maintain a stable body temperature despite fluctuating environmental conditions. Like people, they are endothermic homeotherms—or more colloquially, "warm-blooded."

What animals are exothermic?

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.

Are lizards endothermic?

Lizards are ectotherms. They need external heat to warm up. This is because they are cold blooded animals.

Are sharks endothermic?

Most sharks, like most fishes, are cold blooded, or ectothermic. Their body temperatures match the temperature of the water around them. There are however 5 species of sharks that have some warm blooded, or endothermic capabilities.

Are ducks endothermic?

Avian embryos begin life with an ectothermic metabolic phenotype and are incapable of regulating body temperature by internal heat production (30), but precocial species, like the Pekin duck (Anas platyrhynchos domestica), develop an endothermic metabolic phenotype rapidly upon hatching.

Is a seahorse endothermic or ectothermic?

Seahorses are endothermic because they live in the sea (under water).

Are monkeys endothermic?

Therefore all primates (such as humans, apes, and monkeys), cats (tigers, cheetahs, and domestic cats), rodents (rats, beavers, and chipmunks), marsupials (kangaroo), weasels (badgers and meerkats), monotremes (platypuses), sea mammals (whales, seals, walruses, manatees, and dolphins), dogs, pigs, and elephants are ...

Are frogs endothermic?

Frogs are ectothermic amphibians who are unable to regulate their temperatures internally like birds or mammals. Instead they need to warm up using other things outside their bodies- this action is called thermoregulation. Ectotherms use behavioural mechanisms to control their body temperatures.

Are Lions endothermic?

Endothermic animals must eat much more often than ectothermic animals since it takes energy to maintain a constant body temperature. For example, a lion must eat its weight in food every seven to ten days.

Are mammals endothermic?

endotherm, so-called warm-blooded animals; that is, those that maintain a constant body temperature independent of the environment. The endotherms primarily include the birds and mammals; however, some fish are also endothermic.

Are there any endothermic reptiles?

Endotherms (like us) are able to create their own heat through metabolic reactions (these use energy to create heat). As reptiles are unable to do this, they have to maintain their body temperature another way, mostly by changing behaviour.

Are snakes endothermic?

Snakes are reptiles and all reptiles are ectothermic (ecto = from the outside, thermic = temperature). This means that they obtain body heat from their environment. Mammals, such as humans, are endothermic (endo = from the inside, thermic = temperature) or warm-blooded.
