Which group of animals typically lays eggs and is characterized by scaly skin?

The group of animals that typically lays eggs and is characterized by scaly skin is reptiles. Reptiles, such as snakes, lizards, turtles, and crocodiles, possess several distinctive features, one of which is their dry, scaly skin that helps to prevent water loss. This adaptation is particularly important for survival in various terrestrial environments.

In terms of reproduction, many reptiles also reproduce by laying eggs, although some give birth to live young. The eggs of reptiles are often leathery or hard-shelled, providing protection to the developing embryo. This reproductive strategy is crucial for their ecological niches, allowing them to reproduce successfully across different habitats.

Understanding the unique characteristics of reptiles helps distinguish them from other animal groups. Mammals, for instance, are primarily characterized by their fur and mammary glands, while birds have feathers and lay hard-shelled eggs. Amphibians, on the other hand, have moist skin and typically reproduce in water, laying jelly-like eggs. This context reinforces why reptiles are specifically associated with the traits mentioned in the question.
