Henri Coutière
François Louis Henri Coutière (4 March 1869 in Saulzet – 23 August 1952 in Orvilliers) was a French zoologist, who specialized in the field of carcinology (crustaceans). In 1895 he received his bachelor's degree in natural sciences, and during the following year, obtained his pharmacy degree 1st class. By way of a recommendation from Alphonse Milne-Edwards, he embarked on a zoological mission to the Red Sea in 1897 on behalf of the Muséum d'Histoire Naturelle. In 1899 he was named ''chef de service'' under Milne-Edwards in the laboratory of anatomic zoology at the École des hautes études.François Louis Henri Coutière Société d'Histoire de la Pharmacie In 1899 he obtained his doctorate in natural sciences with a dissertation-thesis on the [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saipan
Saipan ( ch, Sa’ipan, cal, Seipél, formerly in es, Saipán, and in ja, 彩帆島, Saipan-tō) is the largest island of the Northern Mariana Islands, a commonwealth of the United States in the western Pacific Ocean. According to 2020 estimates by the United States Census Bureau, the population of Saipan was 43,385, a decline of 10% from its 2010 count of 48,220. The legislative and executive branches of Commonwealth government are located in the village of Capitol Hill on the island while the judicial branch is headquartered in the village of Susupe. Since the entire island is organized as a single municipality, most publications designate Saipan as the Commonwealth's capital. As of 2015, Saipan's mayor is David M. Apatang and the governor of the Northern Mariana Islands is Ralph Torres. History Prehistory Traces of human settlements on Saipan have been found by archaeologists ranging over 4,000 years, including petroglyphs, ancient Latte Stones, and other artifa ...

Crustaceans Of The Indian Ocean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by thei ...

Collector Urchin
''Tripneustes gratilla'', the collector urchin, is a species of sea urchin. Collector urchins are found at depths of in the waters of the Indo-Pacific, Hawaii, the Red Sea, and The Bahamas. They can reach in size. Description Collector urchins are dark in color, usually bluish-purple with white spines. The pedicles are also white, with a dark or black base. Individuals found at Green Island had orange-tipped spines. The spines of some specimens are wholly orange, while those of others are only orange-tipped or completely white. This color disappears when the individual dies or is taken out of the ocean, and is difficult to preserve. Collector urchins reach in size. Debris tends to "collect" on these urchins, hence their name. Unlike some other sea urchins, collector urchins graze continually, day and night. They graze near the substrate, and their diet includes algae, periphyton, and seagrass. Most collector urchins feed on seagrass fronds; this has an ecological impac ...

Echinometra Mathaei
''Echinometra mathaei'', the burrowing urchin, is a species of sea urchin in the family Echinometridae. It occurs in shallow waters in the Indo-Pacific region. The type locality is Mauritius. Description ''Echinometra mathaei'' grows to a test diameter of about . The colour is quite variable but the test is usually a dark colour. The spines are sometimes green and purple with purple tips or entirely green with purple tips but this sea urchin can be distinguished from other species by a characteristic pale ring at the base of each spine.

Flower Urchin
''Toxopneustes pileolus'', commonly known as the flower urchin, is a widespread and commonly encountered species of sea urchin from the Indo-West Pacific. It is considered highly dangerous, as it is capable of delivering extremely painful and medically significant stings when touched. It inhabits coral reefs, seagrass beds, and rocky or sandy environments at depths of up to . It feeds on algae, bryozoans, and organic detritus. Its common name is derived from its numerous and distinctively flower-like pedicellariae, which are usually pinkish-white to yellowish-white in color with a central purple dot. It possesses short and blunt spines, though these are commonly hidden beneath the pedicellariae. The rigid "shell" ( test) is a variegated deep red and gray in color, though in rare cases it may be greenish to light purple. Taxonomy ''Toxopneustes pileolus'' is one of four species belonging to the genus ''Toxopneustes''. It belongs to the family Toxopneustidae in the order ...

Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, echinode ...

Subtidal
The neritic zone (or sublittoral zone) is the relatively shallow part of the ocean above the drop-off of the continental shelf, approximately in depth. From the point of view of marine biology it forms a relatively stable and well-illuminated environment for marine life, from plankton up to large fish and corals, while physical oceanography sees it as where the oceanic system interacts with the coast. Definition (marine biology), context, extra terminology In marine biology, the neritic zone, also called coastal waters, the coastal ocean or the sublittoral zone, refers to that zone of the ocean where sunlight reaches the ocean floor, that is, where the water is never so deep as to take it out of the photic zone. It extends from the low tide mark to the edge of the continental shelf, with a relatively shallow depth extending to about 200 meters (660 feet). Above the neritic zone lie the intertidal (or eulittoral) and supralittoral zones; below it the continental slope beg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intertidal
The intertidal zone, also known as the foreshore, is the area above water level at low tide and underwater at high tide (in other words, the area within the tidal range). This area can include several types of habitats with various species of life, such as seastars, sea urchins, and many species of coral with regional differences in biodiversity. Sometimes it is referred to as the ''littoral zone'' or '' seashore'', although those can be defined as a wider region. The well-known area also includes steep rocky cliffs, sandy beaches, bogs or wetlands (e.g., vast mudflats). The area can be a narrow strip, as in Pacific islands that have only a narrow tidal range, or can include many meters of shoreline where shallow beach slopes interact with high tidal excursion. The peritidal zone is similar but somewhat wider, extending from above the highest tide level to below the lowest. Organisms in the intertidal zone are adapted to an environment of harsh extremes, living in wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Society Islands
The Society Islands (french: Îles de la Société, officially ''Archipel de la Société;'' ty, Tōtaiete mā) are an archipelago located in the South Pacific Ocean. Politically, they are part of French Polynesia, an overseas country of the French Republic. Geographically, they form part of Polynesia. The archipelago is believed to have been named by Captain James Cook during his first voyage in 1769, supposedly in honour of the Royal Society, the sponsor of the first British scientific survey of the islands; however, Cook wrote in his journal that he called the islands ''Society'' "as they lay contiguous to one another." History Dating colonization The first Polynesians are understood to have arrived on these islands around 1000AD. Oral history origin The islanders explain their origins in term of a orally transmitted story. The feathered god Ta'aroa lay in his shell. He called out but no-one answered, so he went back into his shell, where he stayed for aeons. When he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
