Chordates, members of the phylum Chordata, are part of the clade Deuterostomia. Chordates include the vertebrates (animals that have a vertebral column, or backbone) as well as three groups of invertebrates.
Part A - Derived characters of chordates
All chordates share a set of derived characters during at least some part of their life.
Drag the labels to their correct locations on the diagram of chordate characters below. Use blue labels for blue targets and pink labels for pink targets.
