echinodermatan. pl. [NL., fr. Gr. 'echi^nos hedgehog, sea urchin + de`rma, -atos, skin.].
     One of the grand divisions of the animal kingdom. By many writers it was formerly included in the Radiata.  [1913 Webster]
    " The species usually have an exterior calcareous skeleton, or shell, made of many pieces, and often covered with spines, to which the name. They may be star-shaped, cylindrical, disk-shaped, or more or less spherical. The body consists of several similar parts (spheromeres) repeated symmetrically around a central axis, at one end of which the mouth is situated. They generally have suckers for locomotion. The group includes the following classes: Crinoidea, Asterioidea, Ophiuroidea, Echinoidea, and Holothurioidea. See these words in the Vocabulary, and also Ambulacrum."  [1913 Webster]
