what are reptiles

Reptiles are a type of vertebrate animal characterized by a long, flat body, often covered in scales. Their limbs are relatively short and generally four-legged. Reptiles are mainly divided into four categories: lizards, snakes, turtles and crocodiles.

1. Lizard: Lizard is a type of reptile with a relatively long body, usually with four limbs. The surface of their skin is protected by horny scales, and they can shed themselves to cope with attacks. They have strong bionic characteristics.

2. Snakes: Snakes are reptiles without limbs. They usually have very flexible bodies and can rely on the scales on their abdomen to rub against the ground when moving. Their teeth are sharp and capable of catching prey of all sizes.

3. Turtle: Turtle is a type of hard-shelled animal with a carapace and plastron. It has a relatively short body, flat and strong limbs, and its head and tail can be retracted into the shell to protect itself.

4. Crocodile: Crocodile is a large reptile with a flat head and a large mouth. They have strong limbs, can move freely on land and water, and make a living by preying on small mammals, fish, etc.

It should be noted that although reptiles have many similarities in morphology and living habits, there are also significant differences between different species. At the same time, reptiles also play an important role and value in maintaining ecological balance and environmental protection.
