What type of animal classification do mammals belong to?

Mammals belong to the classification known as Mammalia. This classification encompasses a diverse group of animals characterized by several unique traits, including the presence of mammary glands that produce milk for feeding their young, hair or fur on their bodies, and three bones in the inner ear that are critical for hearing. Mammalia is distinguished from other classes of animals such as Aves, which includes birds; Reptilia, which includes reptiles like lizards and snakes; and Amphibia, which includes frogs and salamanders. Each of these classes has its own distinctive characteristics that set them apart from mammals, making Mammalia the correct classification for mammals.
