Reptiles

Reptiles are a group of vertebrate animals that includes snakes, lizards, turtles, tortoises, and crocodiles. They are generally recognized by their skin covered with scales, which helps reduce water loss, and by their ability to live in many different environments.

Unlike mammals and birds, reptiles are ectothermic animals, meaning that they rely on external sources of heat to regulate their body temperature. Many reptiles warm themselves by basking in the sun and move to cooler places when they need to lower their temperature.

Most reptiles lay eggs with protective shells, although some species give birth to live young. Their diets vary widely: some eat insects, others feed on plants, and some are predators that hunt fish, birds, or other animals.

Reptiles have developed many adaptations that help them survive, such as camouflage, strong jaws, venom, or protective shells. They play important roles in ecosystems by controlling populations of other organisms and contributing to food chains. Today, many reptile species are threatened by habitat destruction, pollution, illegal trade, and climate change.
