vertebrate

A vertebrate is an animal that has a backbone and a skeleton. Vertebrate animals include humans.

When you think about vertebrates, think about bones: this word has to do with animals that have a lot of bones, in the form of a skeleton. It especially refers to animals with a backbone, which protects their spinal cord. Vertebrates have many bones, including a skull which protects their brains, which tend to be large. People, dogs, horses, lizards, dogs, cats, and many other animals are in the vertebrate category. Animals without a backbone are called invertebrates.
