Vernacular name: featherstar Taxonomy: Animalia - Echinodermata - Crinoidea Organism remarks: Species ID updated based on image. The largest living Sea Lily is called Metacrinus superbus. With a family tree rooted in almost 500 million years of history, they are the senior group of living echinoderms. Sea lilies are ancient, having reached their peak in the Middle Mississippian period; about 5,000 fossil species are known. There are about 230 species living today. Most of the sea lilies remain stalked throughout life; their movements include bending the stalk and the arms and crawling. The mouth and ambulacral grooves are on the upper surface.

Global Biodiversity Information Facility. ... 33 results for CLASS: Crinoidea Some of the displayed records may not be available for commercial use. The Articulata are differentiated from the extinct subclasses by their lack of an anal plate in the adult stage and the presence of an entoneural system. As mentioned above, Moore & Teichert (1978) recognized the four major lineages that they identified as subclasses (Camerata, Inadunata, Flexibilia, and Articulata), and they placed the single species of Echmatocrinus into its own subclass, as the primitive, basal crinoid. ... 465 results for CLASS: Crinoidea Some of the displayed records may not be available for commercial use.
