Definition

Invertebrates are animals that lack a backbone or spinal column, encompassing a diverse range of species such as insects, mollusks, and crustaceans. Vertebrates, on the other hand, are animals that possess a backbone, including groups such as mammals, birds, reptiles, amphibians, and fish.

Summary

Invertebrates and vertebrates represent the two major groups of animals, distinguished primarily by the presence or absence of a backbone. Invertebrates, which include creatures like jellyfish, insects, and mollusks, make up about 95% of all animal species. They exhibit a wide range of forms and adaptations that allow them to thrive in various environments. Vertebrates, on the other hand, include mammals, birds, reptiles, amphibians, and fish, characterized by their complex skeletal structures and advanced nervous systems. Understanding the differences between these two groups is crucial for studying biology and ecology. Both invertebrates and vertebrates play vital roles in ecosystems, contributing to biodiversity and ecological balance. By learning about their characteristics, adaptations, and interactions, we gain insights into the complexity of life on Earth and the importance of conservation efforts to protect these diverse species.
