Echinodermata,ere are five extant subtaxa, Crinoidea (e.g., sea lilies and feather stars), Asteroidea (e.g., sea stars), Ophiuroidea (e.g., brittle stars), Echinoidea (e.g., sea urchins), and Holothuroidea (e.g., sea cucumbers) (Fig. 1.1).

Echinodermata together with Hemichordata form the clade Ambulacraria (to which some authors add the enigmatic Xenacoelomorpha group). This grouping is the sister to the Chordata.
