Taxonomic Key
Use the following taxonomic groupings and organisms in the next key. You must include all of them. In two cases, you will include both the polyp and medusa forms in the key. (Hint: They do not have to be near each other in the key). Remember, you need 2 features per step. You can make a key to the phyla and then separate keys for the phyla that have multiple specimens. A few of the higher taxonomic levels will not have a corresponding specimen.

Key Part VI Chaetognatha and Ecdysozoa
Use the following taxonomic groupings and specimens (on pg2) in the next key. You must include all of them. Remember, you need 2 features per step and at least one must be a morphological feature. A few of the higher taxonomic levels will not have a corresponding specimen. For the specimens, you must refer to the specimens we worked on in class. You will not get credit if it is clear you are using a different specimen from the same genus or similar common name.
