What is Class Crinoidea?

This Class includes the sea lilies and the feather stars. What makes them different from the other Echinoderms is the placement of their mouth and anus, which are both located on their upper body surface. They can have many arms (50 to 200) that are extend upward and outward. These arms bear tube feet, which function in filter feeding. One type of crinoid remains attached to the substrate with a stalk, and the other type can either creep along the bottom, or swim with their feathery arms.
