Chrysiptera Hemicyanea
''Chrysiptera hemicyanea'', known commonly as the azure damselfish, azure demoiselle, half-blue demoiselle, and yellow-dipped damsel, is a species of damselfish. Etymology The generic name, ''Chrysiptera'', is a compound of the Greek words ''chrysos'', meaning "golden" and ''pteron'' meaning "fin" or "wing", while the specific name, ''hemicyanea'', means "half blue" referring to the blue head and upper body. Distribution It is native to the eastern Indian Ocean and western Pacific.

Max Carl Wilhelm Weber
Max Carl Wilhelm Weber van Bosse or Max Wilhelm Carl Weber (5 December 1852, in Bonn – 7 February 1937, in Eerbeek) was a German-Dutch zoologist and biogeographer. Weber studied at the University of Bonn, then at the Humboldt University in Berlin with the zoologist Eduard Carl von Martens (1831–1904). He obtained his doctorate in 1877. Weber taught at the University of Utrecht then participated in an expedition to the Barents Sea. He became Professor of Zoology, Anatomy and Physiology at the University of Amsterdam in 1883. In the same year he received naturalised Dutch citizenship. His discoveries as leader of the Siboga Expedition led him to propose Weber's line, which encloses the region in which the mammalian fauna is exclusively Australasian, as an alternative to Wallace's Line. As is the case with plant species, faunal surveys revealed that for most vertebrate groups Wallace’s line was not the most significant biogeographic boundary. The Tanimbar Island group, and ...

Damselfish
Damselfish are those within the subfamilies Abudefdufinae, Chrominae, Lepidozyginae, Pomacentrinae, and Stegastenae within the family Pomacentridae. Most species within this group are relatively small, with the largest species being about 30cm (12 in) in length. Most damselfish species exist only in marine environments, but a few inhabit brackish or fresh water. These fish are found globally in tropical, subtropical, and temperate waters. Habitat in tropical rocky or coral reefs, and many of those are kept as marine aquarium pets. Their diets include small crustaceans, plankton, and algae. However, a few live in fresh and brackish waters, such as the freshwater damselfish, or in warm subtropical climates, such as the large orange Garibaldi, which inhabits the coast of southern California and the Pacific Mexican coast. Foraging The domino damselfish '' D. albisella'' spends the majority (greater than 85%) of its daytime hours foraging. Larger individuals typically fo ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Malta
Malta ( , , ), officially the Republic of Malta ( mt, Repubblika ta' Malta ), is an island country in the Mediterranean Sea. It consists of an archipelago, between Italy and Libya, and is often considered a part of Southern Europe. It lies south of Sicily (Italy), east of Tunisia, and north of Libya. The official languages are Maltese and English, and 66% of the current Maltese population is at least conversational in the Italian language. Malta has been inhabited since approximately 5900 BC. Its location in the centre of the Mediterranean has historically given it great strategic importance as a naval base, with a succession of powers having contested and ruled the islands, including the Phoenicians and Carthaginians, Romans, Greeks, Arabs, Normans, Aragonese, Knights of St. John, French, and British, amongst others. With a population of about 516,000 over an area of , Malta is the world's tenth-smallest country in area and fourth most densely populated sovereign cou ...

Coral Bleaching
Coral bleaching is the process when corals become white due to various stressors, such as changes in temperature, light, or nutrients. Bleaching occurs when coral polyps expel the zooxanthellae (dinoflagellates that are commonly referred to as algae) that live inside their tissue, causing the coral to turn white. The zooxanthellae are photosynthetic, and as the water temperature rises, they begin to produce reactive oxygen species. This is toxic to the coral, so the coral expels the zooxanthellae. Since the zooxanthellae produce the majority of coral colouration, the coral tissue becomes transparent, revealing the coral skeleton made of calcium carbonate. Most bleached corals appear bright white, but some are blue, yellow, or pink due to pigment proteins in the coral. The leading cause of coral bleaching is rising ocean temperature due to climate change. A temperature about 1 °C (or 2 °F) above average can cause bleaching.

Artificial Reef
An artificial reef is a human-created underwater structure, typically built to promote marine life in areas with a generally featureless bottom, to control erosion, block ship passage, block the use of trawling nets, or improve surfing. Many reefs are built using objects that were built for other purposes, such as by sinking oil rigs (through the Rigs-to-Reefs program), scuttling ships, or by deploying rubble or construction debris. Other artificial reefs are purpose-built (e.g. the reef balls) from PVC or concrete. Shipwrecks may become artificial reefs when preserved on the seafloor. Regardless of construction method, artificial reefs generally provide hard surfaces where algae and invertebrates such as barnacles, corals, and oysters attach; the accumulation of attached marine life in turn provides intricate structures and food for assemblages of fish. History The construction of artificial reefs began in ancient times. Persians blocked the mouth of the Tigris River to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chrysiptera Rollandi
''Chrysiptera rollandi'', commonly known as Rolland's demoiselle, is a species of damselfish in the family Pomacentridae. Distribution Rolland's demoiselle is widespread throughout the tropical waters of the central Indo-Pacific region. It lives on reefs among corals and in lagoons and harbors. Description The Rolland's demoiselle is a small size fish and can reach a maximum size of in length. It is dark brown with blue streaks and a cream-colored belly. It is of some commercial importance in the aquarium trade. In aquarium It is not very aggressive in attempting to extend territory but strongly territorial in protecting its ownership of area.
