    1. Describe characteristics for deuterostomes.
    2. List phyla with deuterostomes.
    3. List the subphyla of chordates and give an example of each.
    4. Describe the general characteristics of echinoderms.
    5. List and describe the four chordate characteristics.

    Identify the parts of the chordate?

    IDENTIFY THESE BODY PARTS OF THE FROG? Put structure under its images

    Identify all you can recognize. I know that some are hard to see.
