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.
