Learning types of animals builds vocabulary and science knowledge at the same time. Clear examples and simple classification help students remember animal groups easily.
Types of Animals by Body Structure
Animals can also be divided into two large groups.
Vertebrates Invertebrates
Vertebrates have a backbone.
Mammals are vertebrates. Birds are vertebrates. Reptiles are vertebrates. Amphibians are vertebrates. Fish are vertebrates.
Example sentence:
