Earthworms are neither reptiles nor amphibians; they actually belong to a separate group of animals known as annelids. These creatures are characterized by their segmented bodies and can be found in various environments, primarily in soil.
Reptiles, such as snakes and lizards, are land-dwelling vertebrates with scales and typically lay eggs with a hard shell. Amphibians, including frogs and salamanders, are also vertebrates but spend part of their lives in water and can breathe through their skin. Earthworms, however, do not have a backbone, scales, or lungs, nor do they go through a metamorphosis like amphibians. Instead, they breathe through their skin and thrive in moist environments.
This classification helps us understand the diversity of life on Earth and the different adaptations that organisms have developed to survive in their habitats. So, while earthworms play a vital role in soil health and agriculture, their biological classification distinctly separates them from reptiles and amphibians.
