You discover a new animal. You identify it as a Chordate. You now need to determine its class. Ask three questions below that would provide you with enough evidence to properly classify this organism. (For example: What does it eat? but don't use that one) You will not have to answer the questions nor will you have to actually classify the organism. You will be graded on whether or not your questions can lead you to the answer of what class this organism belongs in.
