Centrostephanus Longispinus
''Centrostephanus longispinus'', the hatpin urchin, is a species of sea urchin in the family Diadematidae. There are two subspecies, ''Centrostephanus l. longispinus'', found in the eastern Atlantic and Mediterranean Sea and ''Centrostephanus l. rubricingulus'', found in the western Atlantic. Taxonomy In 1940, Mortenson believed that ''C. longispinus'' and ''C. rubicingulus'' were closely related species but that they could be distinguished because ''C. longispinus'' has smaller and fewer secondary interambulacral tubercles. In 1975, Fell re-examined the genus but was unable to find sufficient differences to justify separating them into two species. He suggested that ''C. rubicingulus'' should be considered a sub-species of ''C. longispinus''. Nor could he reliably distinguish the pair from ''C. besnardi'' except by the location from which they had been collected (''C. besnardi'' is from the eastern Pacific). He was also unable to distinguish between juveniles of '' C. coronatus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sea Urchin At South East Bay, Three Kings Islands PA121527
The sea, connected as the world ocean or simply the ocean, is the body of salty water that covers approximately 71% of the Earth's surface. The word sea is also used to denote second-order sections of the sea, such as the Mediterranean Sea, as well as certain large, entirely landlocked, saltwater lakes, such as the Caspian Sea. The sea moderates Earth's climate and has important roles in the water, carbon, and nitrogen cycles. Humans harnessing and studying the sea have been recorded since ancient times, and evidenced well into prehistory, while its modern scientific study is called oceanography. The most abundant solid dissolved in seawater is sodium chloride. The water also contains salts of magnesium, calcium, potassium, and mercury, amongst many other elements, some in minute concentrations. Salinity varies widely, being lower near the surface and the mouths of large rivers and higher in the depths of the ocean; however, the relative proportions of dissolved salts vary li ...
