Answer 2

Answer:

These animals are known as reptiles

Explanation:

Reptiles are a class of vertebrates made up mostly of snakes, turtles, lizards, and crocodilians. These animals are most easily recognized by their dry, scaly skin. Almost all reptiles are cold-blooded, and most lay eggs—though some, like the boa constrictor, give birth to live young.

A vertebrate is an animal with a spinal cord surrounded by cartilage or bone. The word comes from vertebrae, the bones that make up the spine. Animals that are not vertebrates are called invertebrates. Vertebrates include birds, fish, amphibians, reptiles, and mammals.
