Answer:
MAMMAL - Mammals are a group of vertebrate animals constituting the class Mammalia, and characterized by the presence of mammary glands which in females produce milk for feeding their young, a neocortex, fur or hair, and three middle ear bones.
REPTILE - Reptiles, as most commonly defined, are the animals in the class Reptilia, a paraphyletic grouping comprising all amniotes except synapsids and Aves. Living reptiles comprise turtles, crocodilians, squamates and rhynchocephalians.
AMPHIBIAN - Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems.
BIRD - Birds are a group of warm-blooded vertebrates constituting the class Aves, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.
FISH - Instead, there are 3 main classes, groups or types of fish: bony fish (Osteichthyes), jawless fish (Agnatha) and cartilaginous fish (Chondrichthyes). Fish are the most diverse group among the vertebrates, with over 33,000 different types of fish species.
