What are the main animal classifications?

Animals are classified into several main categories based on their characteristics and evolutionary relationships. The main animal classifications are mammals, birds, reptiles, amphibians, and fish. Mammals are warm-blooded animals that typically give birth to live young and nurse them with milk produced by mammary glands. Birds are warm-blooded, feathered animals with beaks and lay eggs. Reptiles are cold-blooded animals with scales or shells, and they lay eggs. Amphibians are cold-blooded animals that typically have moist skin and undergo metamorphosis from aquatic larvae to terrestrial adults. Fish are cold-blooded animals that live in water and breathe through gills. Each classification has its own unique characteristics and adaptations that help them thrive in their environments.
