Main Differences Between Vertebrates and Invertebrates in the Animal Kingdom
Vertebrates and invertebrates are two main classifications of animals in the animal kingdom. The primary distinction between the two lies in their anatomical structure, particularly their skeletal systems.
Vertebrates
Vertebrates are animals that possess a backbone or spinal column composed of individual vertebrae. This backbone provides structural support and protection for the spinal cord, a key component of the central nervous system. Some examples of vertebrates include mammals, birds, reptiles, amphibians, and fish.
Invertebrates
Invertebrates, on the other hand, are animals that do not have a backbone or spinal column. Instead, their bodies are supported by other means such as an exoskeleton (insects) or a hydrostatic skeleton (jellyfish). Invertebrates comprise the vast majority of animal species and include organisms like insects, spiders, worms, mollusks, and crustaceans.
Summary
In conclusion, the main differences between vertebrates and invertebrates in the animal kingdom are the presence of a backbone in vertebrates and the absence of a backbone in invertebrates. This fundamental distinction influences their overall body structure, movement, and evolutionary history.
