Reptiles and amphibians belong to the kingdom Animalia. This kingdom encompasses all multicellular organisms that are heterotrophic, meaning they cannot produce their own food and must consume other organisms for energy. Within this kingdom, reptiles and amphibians are classified as two distinct classes of vertebrates, showcasing their own unique characteristics and adaptations.
Reptiles, such as snakes, lizards, and turtles, are primarily characterized by their scaly skin and the ability to lay hard-shelled eggs, which allows them to thrive in a variety of terrestrial habitats. Amphibians, on the other hand, including frogs, salamanders, and toads, typically undergo metamorphosis, starting their lives in water with gills and transforming into air-breathing adults capable of living on land.
Both groups play crucial roles in their ecosystems and provide a glimpse into the diversity of life within the Animalia kingdom.
