An animal dichotomous key is a tool for identifying organisms or objects in nature, such as plants, animals, or rocks. The key comprises a series of paired statements or clues about features or characteristics that serve as a step-by-step guide to identifying each entity. As the user progresses through the steps, the clues gradually narrow the list of possible entities until all are identified. Animal dichotomous keys can be used for both biological classification and identification. The word dichotomous comes from the Greek words for "two parts." Each step in the key offers two opposing options for a characteristic.
