Echinoderms are one branch of the deuterostome line of animal evolution, the branch to which Chordates also belong. Narrated modules cover phylum characteristic 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).
