ABSTRACT
Crinoid, or, any member of a class of colorful, plantlike sea animals related to the starfish. There are two kinds of crinoids: the sea lilies and the feather stars. As soon as they hatch, the sea lilies develop jointed stalks with which they attach themselves for life to an underwater surface, usually a rock. The feather stars also develop stalks for attachment as soon as they hatch, but as they mature, they break free of their stalks to become free-swimming. The crown, or body, of a sea lily is cup-shaped, with many branching, feathery arms that wave to and fro, seizing small sea creatures for food. Mature feather stars have similar crowns, but no stalks.
