Echinoderms are one branch of the deuterostome line of animal evolution, the branch to which Chordates also belong. Modules cover phylum characteristics and key biological details for five classes: sea stars; brittle stars and basket stars; sea urchins and sand dollars (including developmental stages); sea cucumbers; and crinoids (feather stars). The Echinoderms Image Bank with 120 still images is organized for lecture, discussion and review plus the PDF teaching guide is included on the DVD.
