Aves are warm-blooded, arboreal animals and birds. The Aves class includes animals and creatures with both limbs and wings.
Reptiles, or cold-blooded animals that dwell on land, are members of the Reptilia order. They are animals that live on the ground.
The presence of teeth, air-breathing bodies, and scales on the body distinguish animals and organisms belonging to the Reptilia class, known as vertebrates.
Key Takeaways
- Aves are warm-blooded birds, while reptiles are cold-blooded vertebrates.
- Aves have feathers, while reptiles have scales.
- Aves lay hard-shelled eggs, whereas reptiles lay soft-shelled eggs.
Aves vs Reptilia
The difference between Aves and Reptilia is that the existence of a four-chambered heart, forelimbs in the shape of wings, lightweight bones, and feathers distinguishes animals belonging to the Aves class. Whereas Reptilia, known as vertebrates, are animals or organisms with teeth, air-breathing bodies, and scales on their bodies. Reptilia creatures do not have wings. They do, however, have limbs. Snake is the only creature without limbs.
Aves animals and organisms have both limbs and wings on their bodies. Aves creatures have an exoskeleton with claws and feathers. All Aves birds have four-chambered hearts.
They, like humans, have two atria and two ventricles. Aves animals have feathers and teeth. Aves, on the other hand, have beaks, which are modified versions of teeth.
Aves animals and birds are arboreal warm-blooded animals.
Reptilia animals have a dry and scaly exoskeleton. Reptiles and Reptilia species have three-chambered hearts. There are two atria and one ventricle in them.
The crocodile, on the other hand, is an exception, as it has a four-chambered heart. Teeth are present in only a small fraction of Reptilia animals.
The animals in this category, however, do not have feathers. Reptiles are cold-blooded land creatures. They are classified as land animals.

What is Reptilia?
Only a small percentage of Reptilia animals have teeth. The creatures in this category, on the other hand, do not have feathers. Reptiles, or cold-blooded animals that dwell on land, are members of the Reptilia family.
They are classified as terrestrial creatures.
The Reptilia class includes organisms that do not have wings. They do, however, have limbs on their bodies. Snake is the only creature that doesn’t have limbs.
Reptiles have a dry, scaly exoskeleton. Reptiles and Reptilia species have hearts with three chambers.
The presence of teeth, air-breathing bodies, and scales on the body distinguish animals or organisms belonging to the Reptilia class, known as vertebrates.
They have one ventricle and two atria. The crocodile, on the other hand, has a four-chambered heart.
Main Differences Between Aves and Reptilia
- Animals belonging to the Class Aves are characterized by the presence of a four-chambered heart, forelimbs in the form of wings, lightweight bones, and feathers. On the other hand, animals or organisms belonging to the class Reptilia, also called vertebrates, are characterized by the presence of teeth, air-breathing bodies, and possessing scales on their body.
- The animals or organisms belonging to the class Aves possess both limbs and wings on their body. On the other hand, the organisms belonging to the class Reptilia do not wing. However, they possess limbs on their body. Snake is the only exception who does not possess limbs.
- The organisms belonging to the Aves category have an exoskeleton which is characterized by the presence of claws and feathers. On the other hand, the animals of Reptilia possess an exoskeleton that is characterized by the texture of dry and scaly.
- All the birds belonging to the category of Aves possess hearts having four chambers. Like humans, they also have two atria and two ventricles. On the other hand, the reptiles or the animals of Reptilia have hearts of three chambers. They possess two atria and one ventricle. However, the crocodile is an exception that has a four-chambered heart.
- Both feathers and teeth are present in the animals belonging to the category of Aves. However, in Aves, they possess beaks which is the modified version of teeth. On the other hand, a small percentage of animals of Reptilia possess teeth. However, the animals belonging to this category lack feathers.
- Animals and birds of Aves are considered warm-blooded animals which are arboreal. On the other hand, Animals belonging to Reptilia or reptiles are cold-blooded animals that live on the land. They are considered terrestrial animals.
