Clark comprises three suborders (stalkless as adults—Comatulidina A.H. Clark; and two groups that retain their stalk as adults—Bourgueticrinina Sieverts-Doreck; and Guillecrinina Mironov and Sorokina). Comatulida. Comatulida is an order of crinoids. Members of this order are known as feather stars and mostly do not have a stalk as adults. The oral surface with the mouth is facing upwards and is surrounded by five, often divided rays with feathery pinnules. Comatulids live on the seabed and on reefs in tropical and temperate waters.Some species still retain a stalk, which can reach up to 1 meter (3 feet) in length.
