	Cidaris Cidaris ''Cidaris cidaris'' is a species of sea urchin commonly known as the long-spine slate pen sea urchin. It is found in deep water in the eastern Atlantic Ocean and the Mediterranean Sea. Description ''Cidaris cidaris'' has a small central test from which project a number of long, blunt, widely separated primary spines and a dense covering of short secondary spines. The primaries are pale grey, tipped with green and the secondaries are pale green. The test has a diameter of to and the spines are twice as long as this. The sea urchin often has bits of algae, sponge or other organisms adhering to the spines. Distribution ''Cidaris cidaris'' is found in the eastern Atlantic Ocean and the Mediterranean Sea in deep water on coral, rock and gravel bottoms. Its range extends from Cape Verde, the Azores and the Canary Islands northwards to the Faroe Islands and Norway. It is also found on knolls and seamounts at depths down to about .

	Cidaris Blakei ''Cidaris blakei'' is a species of sea urchins of the family Cidaridae. Its armour is covered with spines of three types, one unique type being extended and fan-like, making it easily recognized. Alexander Agassiz first described it scientifically in 1878. It is present on the seabed in deep waters in the Gulf of Mexico and the Bahamas. Taxonomy ''Cidaris blakei'' was first described by the American zoologist Alexander Agassiz in 1878. It was among many deep sea animals dredged up from abyssal depths in the Gulf of Mexico during the explorations of the '' USC&GS George S. Blake'', one of the first United States oceanographic research vessels, and from which it derives its specific name. The genus name is Latin for a headdress or tiara worn by ancient Persian kings.

picture info	Cidaridae Cidaridae is a family of sea urchins in the order Cidaroida. Description and characteristics Cidarid sea urchins are characterized by their stout skeleton : the test is thick and hard, with massive perforated tubercles (never crenulated) surrounded by a crown of secondary tubercles, but no primary tubercles in the interambulacra regions. These tubercles hold massive spines, thick, strong and often very long, and showing sometimes odd shapes (thorny spines, fans, clubs, Christmas trees...). The order Cidaroida is the basalmost of current sea urchins, and most of the species included in this family are abyssal, even if a handful of species remain quite common in tropical shallow waters, like ''Eucidaris'' or ''Phyllacanthus''. Genera According to the World Register of Marine Species (WoRMS), the following genera are included in this family * Subfamily '' Cidarinae'' (Mortensen, 1928a) Genus ''Calocidaris'' (H.L.

All other orders of this subclass, which were even more primitive than the living forms, became extinct during the Mesozoic. Description Their primary spines are much more widely separated than in other sea urchins, and they have no buccal slits. Other primitive features include relatively simple plates in the test, and the ambulacral plates continuing as a series across the membrane that surrounds the mouth.
