To determine whether an organism is an amphibian, bird, fish, insect, invertebrate, reptile, or mammal, one must consider its key characteristics. Amphibians typically have a life cycle that includes both aquatic and terrestrial stages, while birds are characterized by feathers and beaks. Fish are aquatic vertebrates with gills, insects have exoskeletons and six legs, invertebrates lack a backbone, reptiles have scaly skin and lay eggs, and mammals are warm-blooded with fur or hair and usually give live birth. Identifying specific traits can help classify the organism correctly.
