Cyrtocrinida
Cyrtocrinida is an order of sea lilies which contains two suborders and three families. Characteristics Members of this order have stems consisting of a single skeletal unit or a very small number of units. There are no cirri, and the expanded base of the stem attaches directly to the substrate. The calyx may be asymmetrical and consists of five arms attached to five radial ossicles. The arms subdivide at arm ossicle I or II. Families The World Register of Marine Species includes the following groups in the order: * Suborder Cyrtocrinina ** Family Sclerocrinidae Jaekel, 1918 * Suborder Holopodina ** Family Eudesicrinidae Bather, 1899 ** Family Holopodidae Holopodidae is a family of echinoderms belonging to the order Cyrtocrinida Cyrtocrinida is an order of sea lilies which contains two suborders and three families.

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 ...

Cyathidium (echinoderm)
''Saussurea'' is a genus of about 300 species of flowering plants in the tribe Cardueae within the family Asteraceae, native to cool temperate and arctic regions of East Asia, Europe, and North America, with the highest diversity in alpine habitats in the Himalayas and East Asia. Common names include saw-wort and snow lotus, the latter used for a number of high altitude species in East Asia. They are perennial herbaceous plants, ranging in height from dwarf alpine species 5–10 cm tall, to tall thistle-like plants up to 3 m tall. The leaves are produced in a dense basal rosette, and then spirally up the flowering stem. The flowers form in a dense head of small capitula, often surrounded by dense white to purple woolly hairs; the individual florets are also white to purple. The wool is densest in the high altitude species, and aids in the thermoregulation of the flowers, minimising frost damage at night and also preventing ultraviolet light damage from the intense high-altit ...
