Bourgueticrinida
Bourgueticrinida is an order of crinoids that typically live deep in the ocean. Members of this order are attached to the seabed by a slender stalk and are known as sea lilies. While other groups of crinoids flourished during the Permian, bourgueticrinids along with other extant orders did not appear until the Triassic, following a mass extinction event in which nearly all crinoids died out. Taxonomy Bourgueticrinida has traditionally been viewed as an order of Articulata and a sister taxon to the order Comatulida, the feather stars. A study published in 2011 suggested that it should be renamed Bourgueticrinina and viewed as a suborder of Comatulida. Characteristics Sea lilies are crinoids with a calyx and five pairs of feather-like arms standing on a long stalk which is retained throughout the animal's life. This stalk is attached to the substrate by means of an enlarged, terminal disc or alternatively by means of several branching, irregular radicular cirri arising from the ...

Bathycrinus Aldrichianus
''Bathycrinus aldrichianus'' is a species of sea lily, a crinoid in the family Bathycrinidae. It is native to deep water in the North Atlantic Ocean. It was first described by the Scottish marine zoologist Charles Wyville Thomson (who had been chief scientist on the ''Challenger'' Expedition) and named in honour of Pelham Aldrich Admiral Pelham Aldrich, CVO (8 December 1844 – 12 November 1930) was a Royal Navy officer and explorer, who became Admiral Superintendent of Portsmouth Docks. Biography He was born in Mildenhall, Suffolk, the son of Dr. Pelham Aldrich and El ..., a British naval officer and explorer. It is believed to be the crinoid living at the greatest depth. Description ''Bathycrinus aldrichianus'' is a ten-armed sea lily, the first and second arms, the fourth and fifth, and the seventh and eighth having syzygies (being joined together at the base). The arms are connected to the base ring of the crown and consist of a series of jointed rectangular plates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Comatulida
Comatulida is an order of crinoids. Members of this order are known as feather stars and mostly do not have a stalk as adults. The oral surface with the mouth is facing upwards and is surrounded by five, often divided rays with feathery pinnules. Comatulids live on the seabed and on reefs in tropical and temperate waters. Taxonomy Bourgueticrinida, the sea lilies, has traditionally been viewed as an order of Articulata and a sister taxon to Comatulida. A study published in 2011 suggested that it should be renamed Bourgueticrinina and viewed as a suborder of Comatulida. Characteristics Like other echinoderms, comatulids have pentamerous symmetry (five sided) as adults though the larvae have bilateral symmetry. Late in their development, the larvae are attached to the seabed by a stalk, but this is broken at metamorphosis and the juvenile crinoid is free living. The body has an endoskeleton made from a number of articulated calcareous plates known as ossicles covered by a thin ep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
