Tripneustes Ventricosus
''Tripneustes ventricosus'', commonly called the West Indian sea egg or white sea urchin, is a species of sea urchin. It is common in the Caribbean Sea, the Bahamas and Florida and may be found at depths of less than . Description The test of the West Indian sea egg is dark in color, usually black, dark purple or reddish brown, with white spines long. The test can reach in diameter. It is often covered with pieces of seagrass, fragments of shell and other debris in a manner similar to the closely related ''Tripneustes gratilla''.Humann, Paul, ''Reef Creature Identification'', Edited by Ned Deloach. New World Publications, Inc., 1992, p. 292-293. These decorations are held in place by tube feet among the spines and are believed to provide protection from the intense sunlight that penetrates the shallow water. Distribution and habitat The West Indian sea egg is found in shallow parts of the western Atlantic Ocean, the Caribbean Sea and Gulf of Mexico. Its range extends from Berm ...

Echinoidea Genera
Sea urchins () are spiny, globular echinoderms in the class Echinoidea. About 950 species of sea urchin live on the seabed of every ocean and inhabit every depth zone from the intertidal seashore down to . The spherical, hard shells (tests) of sea urchins are round and spiny, ranging in diameter from . Sea urchins move slowly, crawling with tube feet, and also propel themselves with their spines. Although algae are the primary diet, sea urchins also eat slow-moving (sessile) animals. Predators that eat sea urchins include a wide variety of fish, starfish, crabs, marine mammals. Sea urchins are also used as food especially in Japan. Adult sea urchins have fivefold symmetry, but their pluteus larvae feature bilateral (mirror) symmetry, indicating that the sea urchin belongs to the Bilateria group of animal phyla, which also comprises the chordates and the arthropods, the annelids and the molluscs, and are found in every ocean and in every climate, from the tropics to the polar r ...

San Salvador Island
San Salvador Island (known as Watling's Island from the 1680s until 1925) is an island and district of The Bahamas. It is widely believed that during Christopher Columbus's first expedition to the New World, this island was the first land he sighted and visited on 12 October 1492. He named it ''San Salvador'' after Christ the Saviour. Columbus's records indicate that the native Lucayan inhabitants of the territory, who called their island Guanahaní, were "sweet and gentle". History When he made landfall on the small island of San Salvador in October 1492, Columbus thought he had reached the East Indies, which was precisely his quest: to find an all-water route to the Orient so that European traders of precious spices could maximise their profits by cutting out Muslim middlemen. Additionally and more specifically, he was working on behalf of the Spanish to surpass the Portuguese, who had established trade routes around the Horn of Africa, a trans-Atlantic route being presume ...

Burdigalian
The Burdigalian is, in the geologic timescale, an age (geology), age or stage (stratigraphy), stage in the early Miocene. It spans the time between 20.43 ± 0.05 annum, Ma and 15.97 ± 0.05 Ma (million years ago). Preceded by the Aquitanian (stage), Aquitanian, the Burdigalian was the first and longest warming period of the MioceneEdward Petuch, Ph.D. Florida Atlantic University, Department of Geosciences. and is succeeded by the Langhian. Stratigraphic definition The name Burdigalian comes from ''Burdigala'', the Latin name for the city of Bordeaux, France. The Burdigalian Stage was introduced in scientific literature by Charles Depéret in 1892. The base of the Burdigalian is at the first appearance of foram species ''Globigerinoides altiaperturus'' and the top of magnetic chronozone C6An. , an official GSSP for the Burdigalian had not yet been assigned. The top of the Burdigalian (the base of the Langhian) is defined by the first appearance of foram species ''Praeorbulina gl ...
