suresh In zoology, vertebrates and invertebrates are two main classifications of animals based on the presence or absence of a backbone. Vertebrates are animals that have a vertebral column, or backbone, which provides support and protection for the spinal cord. Examples of vertebrates include mammals, birds, reptiles, amphibians, and fish.
On the other hand, invertebrates are animals that do not have a backbone. They make up the vast majority of animal species and include insects, spiders, mollusks, and worms. Invertebrates have a wide range of body structures and adaptations that allow them to thrive in various environments.
Understanding the difference between vertebrates and invertebrates is essential for studying and categorizing different animal species in the field of zoology. By classifying animals based on the presence or absence of a backbone, researchers can better understand the diversity and evolution of the animal kingdom.
