WEBCrinoids are marine invertebrates that make up the class Crinoidea. Crinoids that are attached to the sea bottom by a stalk in their juvenile form are commonly called sea lilies, while the unstalked forms, called feather stars [3] [4] or comatulids, are members of the largest crinoid order, Comatulida.
