Taxonomy science of naming and classifying living things to determine evolutionary relationships
Binomial Nomenclature scientific naming system using the genus and species; used to avoid confusion
Levels of Classification Taxonomy levels starting with the largest and most diverse group (Domain) to the smallest and same group (species) Organisms with more similar levels are more closely related DPCOFGS - Domain, Phylum, Class, Order, Family, Genus, species
Dichotomous Key chart used to identify organism by looking at individual characteristics; numbered list of characteristics to identify if the organism has that trait or not

6 Main Classes of Animals Five vertebrate (animals with backbones) classes are fish, birds, mammals, reptiles, and amphibians. The sixth class is invertebrates (animals lacking a backbone) like insects and spiders.
Fish distinguished from other animals because they have scales, fins, and gills. Being cold-blooded animals, fish need to swim in water of the right temperature to control their body temperature.
Birds group of winged avian animals belongs to the group of warm-blooded creatures. It is easy to identify most birds because of their beak, wings, feathers, and the fact that they start off life in an egg.
Mammals main identifying feature is the fact that they drink their mother’s milk; warm-blooded animals with fur
Reptiles vertebrates that are cold-blooded, egg hatching, and covered in scales; main distinguishing characteristic is their scaly skin; include snakes and lizards, turtles and tortoises, crocodiles and alligators
Amphibians type of animals with gills (like a fish) and lungs (like reptiles). The 3 subclasses of amphibians are frogs and toads, salamanders and newts, and blindworms. have slimy skin or sticky skin that doesn’t have any scales; lay their eggs in water and some release toxins through their skin as defense mechanism
Invertebrates class of animals that don’t have a backbone. This diverse range of animals can include arthropods such as insects, as well as mollusks, worms, jellyfish, snails, and squid. contains around 97% of the animals in the world, cold-blooded animals with no backbone
