Which of the following vertebrates typically live on land and are covered in scales?

Reptiles are the group of vertebrates that typically live on land and are covered in scales. They possess adaptations that allow them to thrive in terrestrial environments, such as protective scales that help prevent water loss, which is crucial for survival outside of aquatic habitats.

This group includes animals like snakes, lizards, turtles, and crocodiles, all of which are primarily adapted to a land-based life. Their dry skin and scaled bodies are significant for regulating moisture and temperature, distinguishing them from other vertebrates.

In contrast, fish are primarily aquatic and have scales, but they do not live on land. Birds, while they are covered in feathers, not scales, are adapted for flight and have different habitats, and amphibians, such as frogs and salamanders, typically have moist skin and undergo both aquatic and terrestrial phases in their life cycles.
