10 difference between reptilia and aves
Answers
1.Birds are endothermic rather than ectothermic.
2.Some reptiles, such as the leatherback turtle, can produce body heat but it isn’t as highly modified a system as it is for birds.
3.Birds have a four chambered heart which, among the living reptiles, only crocodylians have. The others have three chambered hearts
4.Birds have feathers, as well as scales. Other reptiles have scales but no feathers
5.Birds have no teeth, with a bill instead. Most, but not all, reptiles have teeth, except for turtles and a few others.
6.Most birds show a fair amount of care for their young, which is unusual among reptiles with only a handful of exceptions. Crocodylians are the only reptile that have care of their young common across the whole group.
7.Bird eggs have an air space (unusual among reptiles, although crocodylian eggs develop one late in incubation) and have to be turned during incubation, whereas reptile eggs do not.
8.The tail bones of a bird have been reduced and compressed into a tiny nub called a pygostyle. Most reptiles have normal tail vertebrae, although some geckoes also have little nub tails.
9.There habitats are different.
10.It’s worth noting here that, among the reptiles, crocodylians are more closely related to birds than they are to lizards because they share a common ancestor: the archosaurs.

Reptiles
1. They are ectothermic vertebrates.
2. Their skin has scales, but no hair or feathers.
3. They have three-chambered hearts (except for alligators and crocodiles, which have four-chambered hearts).
4. They have claws on their toes (except those which do not have legs, such as legless lizards).
5. They are the first animals, in evolution, to develop the amniotic egg. This allows reptiles to lay eggs on land.
6. Reptiles are cold-blooded animals
7. Their internal temperature will either increase or decrease depending upon the outside temperature.
8. Reptile’s tailbones are composed of normal vertebrae, and they spines bend side to side.
9. Reptiles are born mostly independent and go their own way shortly after hatching, with the exception again being crocodilians.
10.Example: snake, turtle, dinasour
Aves
1. They are endothermic vertebrates.
2. Their skin is covered with feathers.
3. They have four-chambered hearts.
4. Their bones are lightweight and usually hollow.
5. Their forelimbs are modified as wings.
6. They lay eggs.
7. Aves are warm-blooded animals
8. Their bodies maintain a relatively constant internal temperature regardless of the temperature outside.
9.Aves tailbones are compressed into a nub-like pygostyle, and their spine curves up and down.
10. Aves as baby birds are born dependent on their parents, who care for their young until they mature
11. Example: sparrow, penguin, bird, lizard
