The Difference Between Invertebrates and Vertebrates in the Animal Kingdom

In the animal kingdom, the key distinguishing factor between invertebrates and vertebrates lies in their skeletal structure. Vertebrates possess a backbone or spinal column, while invertebrates do not.

Focus Keyword: Invertebrates vs Vertebrates

Invertebrates:

Invertebrates are animals that lack a backbone or spinal column. They make up the vast majority of animal species in the world, including insects, arachnids, worms, and mollusks. Invertebrates rely on their exoskeletons or hydrostatic skeletons for support and protection.

Vertebrates:

Vertebrates are animals with a backbone or spinal column composed of vertebrae. This includes mammals, birds, reptiles, amphibians, and fish. The vertebral column provides structural support and protects the spinal cord, a vital component of the nervous system.

While invertebrates and vertebrates both play crucial roles in the ecosystem, their differences in skeletal structure define their classification within the animal kingdom.
