Mammals are vertebrates that are viviparous or oviparous, breathe with lungs, have hair or fur, and feed their young milk. Birds are oviparous, have feathers and wings, and feed their young. Reptiles are oviparous or viviparous, breathe with lungs or gills, and have scales. Amphibians undergo metamorphosis, breathe with gills or lungs, and have moist skin. Arthropods are the largest invertebrate group including insects, arachnids, myriapods, and crustaceans having exoskeletons and jointed legs. Molluscs include gastropods, bival
