They have a bony endoskeleton with a backbone and jaws; they breathe only with lungs; they have four limbs; their skin is covered with scales; they have amniotic eggs; they are ectothermic.

Is a hagfish an Ectotherm?
Since agnatha are a type of fish, they are therefore ectothermic, as all fish are.
Are lampreys ectothermic?
Chung-Davidson as unusual because sea lampreys are "ectothermic" animals, meaning they do not maintain a constant body temperature - rather, their internal temperature fluctuates with the environment.
What are endothermic tetrapods?
Endothermic tetrapods differ dramatically from ectothermic tetrapods in having a great capacity to sustain vigorous locomotion. ... In modern tetrapods upright posture is correlated with endothermic metabolism. This correlation may have arisen to circumvent ancestral constraints on locomotor stamina.
Which class of vertebrates has some members that are ectotherms and other members are Endotherms?
Reptiles and amphibians are ectotherms, while birds are endotherms. An ectotherm (reptile/amphibian) relies primarily on its external environment to regulate the temperature of its body. Endotherms (birds) are able to regulate their body temperatures by producing heat within the body.
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.
Are pigeons endothermic?
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.
Are stingrays endothermic?
Sharks, stingrays, skates, eels, puffers, seahorses, clownfish are all examples of fishes. Marine mammals are a group of animals that can either partially or completely aquatic vertebrates that have lungs, have hair (at least at one point in their life), produce milk for live birth, and are endothermic.
Are frogs endothermic or ectothermic?
Frogs are ectotherms, this means they get their heat from external sources. They are sometimes called 'cold blooded', but in fact they do not have cold blood, it is just regulated by their environment. In comparison, humans are endotherms and can maintain their body temperature at about 37°C.
Are stingrays vertebrates or invertebrates?
The stingray "is the only vertebrate we've documented that has seasonal changes in tooth shape," Kajiura said. The male stingray uses its sharper teeth to secure himself to a mate during reproduction, as stingrays are rather slippery.
What animals are endothermic?
Endothermic animals are animals that are able to maintain a constant body temperature regardless of their ambient temperature. Endothermic animals include all birds and mammals of the animal kingdom. Even some fish are considered to be endothermic.
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 are ectothermic tetrapods?
Amphibians and reptiles generally obtain the energy to do this from outside their bodies and consequently are called ectotherms, whereas birds and mammals generate most of the energy needed for thermoregulation internally and are called endotherms.
What are endothermic and ectothermic animals?
In general, if an organism uses energy to regulate its body temperature internally, then it is considered endothermic. If an organism instead relies on external environmental factors to regulate its body temperature, then it is considered ectothermic.
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 birds endothermic?
Even though juvenile and adult birds are endothermic and maintain a constant, high body temperature by means of internal heat production, they begin life expressing an ectothermic phenotype.
