The five subgroups of vertebrates are mammals, birds, reptiles, amphibians, and fish. Each subgroup is characterized by distinct features, such as mammary glands in mammals, feathers in birds, scales in reptiles, moist skin in amphibians, and gills in fish. These groups represent a wide range of adaptations to different environments and lifestyles. Together, they make up the phylum Chordata, which is defined by having a backbone.
