Characteristics Members of this order have long slender stems consisting of a large number of identical columnar units. There are no cirri, and the basal disc of the stem attaches directly to the substrate. The calyx is globular or conical, and consists of five widely-spaced, undivided arms attached to five radial ossicles. Distribution Most hyocrinids are found at depths below , in the range , in all the ocean basins and on seamounts. References Articulata (Crinoidea) {{crinoidea-stub ...

picture info	Echinoderms An echinoderm () is any member of the phylum Echinodermata (). The adults are recognisable by their (usually five-point) radial symmetry, and include starfish, brittle stars, sea urchins, sand dollars, and sea cucumbers, as well as the sea lilies or "stone lilies". Adult echinoderms are found on the sea bed at every ocean depth, from the intertidal zone to the abyssal zone. The phylum contains about 7,000 living species, making it the second-largest grouping of deuterostomes, after the chordates. Echinoderms are the largest entirely marine phylum. The first definitive echinoderms appeared near the start of the Cambrian. The echinoderms are important both ecologically and geologically. Ecologically, there are few other groupings so abundant in the biotic desert of the deep sea, as well as shallower oceans. Most echinoderms are able to reproduce asexually and regenerate tissue, organs, and limbs; in some cases, they can undergo complete regeneration from a single limb. Geolo ...
