How to fill out invertebrates dichotomous key

How to fill out a dichotomous key for invertebrates:

1. Start by observing the invertebrate specimen carefully. Take note of its physical characteristics, such as the number of legs, presence of wings, body shape, and other distinguishing features.
2. Begin the dichotomous key by identifying the main characteristics of the invertebrate. For example, if the specimen has wings, it could be categorized as a flying invertebrate, while those without wings would be categorized as non-flying.
3. Create a series of yes or no questions based on the observed characteristics. These questions should help narrow down the possibilities and lead to the correct identification of the invertebrate. For instance, one question could be, "Does the invertebrate have more than six legs?"
4. Each answer to the yes or no questions should lead to a different set of follow-up questions or classifications. It is crucial to consider all possible options and create a comprehensive key that covers a wide range of invertebrates.
5. Continuously refine and revise the key as you identify more invertebrate specimens. The more specimens you analyze, the better you can fine-tune the questions and classifications within the dichotomous key.
