Name an animal for me. There are many different animals in our world. Scientists classify animals into groups to make it easier for people to identify them. Animals are classified into two groups, vertebrate and invertebrates. We will talk about vertebrates and their characteristics.
Scientists use a characteristic to classify animals into two groups.
The characteristic is a backbone. Animals with backbones are called vertebrates. You are a vertebrate because you have a backbone. Stand up and feel your backbone. Place your hand on your lower back.
