Sea lilies (more properly known as crinoids) are marine filter-feeders which latch onto surfaces underwater. A sea lily’s arms extend out from its cup or calyx, the cone-shaped structure at the end of its column. These organisms survive by catching small particles of food with their arms and pulling these scraps into their mouths. Don’t let the flower-like shape of this “lily” deceive you - crinoids are actually animals. (William Ausich 1996, “Phylum Echinodermata”)
