Crinoidea Echinodermata Animalia Flora and Fauna

Crinoidea Echinodermata Animalia Flora and Fauna

The Crinoids include about 625 living species of sea lilies and feather stars. Some have stalks and wave their feathery arms to catch fragments and work them towards their mouths with their tube feet and cilia. The feather stars walk on the tips of their arms, or swim by moving their arms alternately so that half are up and half down at any one time.
