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 .

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. Clark, 1907) ** Genus '' Centrocidaris'' (A. Agassiz, 1904) * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Louis Agassiz
Jean Louis Rodolphe Agassiz ( ; ) FRS (For) FRSE (May 28, 1807 – December 14, 1873) was a Swiss-born American biologist and geologist who is recognized as a scholar of Earth's natural history. Spending his early life in Switzerland, he received a PhD at Erlangen and a medical degree in Munich. After studying with Georges Cuvier and Alexander von Humboldt in Paris, Agassiz was appointed professor of natural history at the University of Neuchâtel. He emigrated to the United States in 1847 after visiting Harvard University. He went on to become professor of zoology and geology at Harvard, to head its Lawrence Scientific School, and to found its Museum of Comparative Zoology. Agassiz is known for observational data gathering and analysis. He made institutional and scientific contributions to zoology, geology, and related areas, including multivolume research books running to thousands of pages.

Hubert Lyman Clark
Hubert Lyman Clark (January 9, 1870 – July 31, 1947) was an American zoologist. The son of Professor William Smith Clark, he was born at Amherst, Massachusetts, and educated at Amherst College and Johns Hopkins University. From 1899 to 1905 he was professor of biology at Olivet College. Beginning in 1905, Clark worked as assistant in invertebrate zoology at the Museum of Comparative Zoology at Harvard University. He was curator of echinoderms from 1910 to 1927, and curator of marine invertebrates and associate professor of zoology beginning 1927. He was awarded the Clarke Medal by the Royal Society of New South Wales in 1947. Work He carried on scientific investigations in Jamaica, Bermuda and Australia, where he collected in 1913, 1929 and 1932, and published many papers dealing with birds, snakes, echinoderms and flowers.
