Vertebrates vs. Invertebrates
Vertebrates vs. Invertebrates: The Animal Kingdom
The animal kingdom is vast and diverse, filled with creatures of all shapes and sizes. To better understand this variety, scientists classify animals into different groups based on their characteristics. Two major groups are vertebrates and invertebrates.
What are Vertebrates?
Vertebrates are animals that have a backbone or spinal column inside their bodies. This backbone protects the spinal cord, which is a bundle of nerves that carries messages between the brain and the rest of the body. Vertebrates also have an internal skeleton made of bone or cartilage. This skeleton provides support and structure.
There are five major groups of vertebrates:
- Vertebrate:
- An animal with a backbone.
- Invertebrate:
- An animal without a backbone.
- Exoskeleton:
- A hard outer covering that protects an animal's body.
- Amphibian:
- An animal that lives both in water and on land.
- Mammal:
- A warm-blooded animal with fur or hair that feeds its young milk.
