Bluespotted Grouper
''Cephalopholis argus'', the peacock hind, roi, bluespotted grouper, and celestial grouper, is a species of marine ray-finned fish, a member of the subfamily Epinephelinae, the groupers, and part of the family Serranidae, which also includes the anthias and sea basses. They come from the Indo-Pacific which is variously a commercial gamefish, an invasive species, and occasionally an aquarium resident. Its species name comes from its resemblance to the "hundred staring eyes" of the monster Argus who had a hundred eyes and was the shepherd of the goddess Hera in Greek mythology. Description This is a medium-sized fish that can reach a length of . Small individuals are dark brown with hundreds of small, dark-edged iridescent blue spots. Larger specimens sometimes develop four to six lighter vertical bars on the back half of its body. Distribution and habitat The species is extremely widely distributed, occurring in warm waters from the Red Sea to South Africa and east to French Po ...

Johann Gottlob Schneider
Johann Gottlob Theaenus Schneider (18 January 1750 – 12 January 1822) was a German classicist and naturalist. Biography Schneider was born at Collm in Saxony. In 1774, on the recommendation of Christian Gottlob Heine, he became secretary to the famous Strasbourg scholar Richard François Brunck, and in 1811, became professor of ancient languages and eloquence at Breslau (chief librarian, 1816) where he died in 1822. Works Of his numerous works the most important was his ''Kritisches griechisch-deutsches Handwörterbuch'' (1797–1798), the first independent work of the kind since Stephanus's ''Thesaurus'', and the basis of F. Passow's and all succeeding Greek lexicons (including, therefore, the contemporary standard ''A Greek-English Lexicon''). A special improvement was the introduction of words and expressions connected with natural history and science. In 1801, he corrected and expanded re-published Marcus Elieser Bloch's ''Systema Ichthyologiae iconibus cx illustratu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argus Panoptes
Argus or Argos Panoptes (, "All-seeing Argos") is a many-eyed giant in Greek mythology. Known for his perpetual vigilance, he served the goddess Hera as a watchman. His most famous task was guarding Io, a priestess of Hera, whom Zeus had transformed into a heifer. Argus's constant watch, with some of his eyes always open, made him a formidable guardian. His eventual slaying by Hermes, on Zeus's orders, is a prominent episode in the myths surrounding him, and his eyes were then incorporated into the peacock's tail by Hera in his honor. Mythology Argus Panoptes () was the guardian of the heifer-nymph Io and the son of Arestor. According to Asclepiades, Argus Panoptes was a son of Inachus, and according to Cercops he was a son of Argus and Ismene, daughter of Asopus. Acusilaus says that he was earth-born ( autochthon), born from Gaia. Probably Mycene (in another version the son of Gaia) was a primordial giant whose epithet ''Panoptes'', "all-seeing", led to his being d ...

Parrotfish
Parrotfish (named for their mouths, which resemble a parrot's beak) are a clade of fish placed in the tribe Scarini of the wrasse family (Labridae). Traditionally treated as their own family (Scaridae), genetic studies have found them to be deeply nested within the wrasses, and they are now treated as a subfamily (Scarinae) or tribe (Scarini) of them. With roughly 95 species, this group's largest species richness is in the Indo-Pacific. They are found in coral reefs, rocky coasts, and seagrass beds, and can play a significant role in bioerosion. Taxonomy Traditionally, the parrotfishes have been considered to be a family level taxon, Scaridae. Although phylogenetic and evolutionary analyses of parrotfishes are ongoing, they are now accepted to be a clade in the wrasses closely related to the tribe Cheilini, and are now commonly referred to as scarine labrids (tribe Scarini, family Labridae). Some authorities have preferred to maintain the parrotfishes as a family-level taxon, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Damselfish
Damselfish are those fish within the subfamilies Abudefdufinae, Chrominae, Lepidozyginae, Pomacentrinae, and Stegastinae within the family Pomacentridae. Most species within this group are relatively small, although the four largest species ('' Hypsypops rubicundus'', '' Microspathodon bairdii'', '' M. dorsalis'' and '' Nexilosus latifrons'') can reach 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 ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moray Eels
Moray eels, or Muraenidae (), are a family of eels whose members are found worldwide. There are approximately 200 species in 15 genera which are almost exclusively marine, but several species are regularly seen in brackish water, and a few are found in fresh water. The English name, ''moray'', dates back to the early 17th century, and is believed to be a derivative from Portuguese , which itself derives from Latin , in turn from Greek , ; these are the Latin and Greek names of the Mediterranean moray. Anatomy The dorsal fin extends from just behind the head along the back and joins seamlessly with the caudal and anal fins. Most species lack pectoral and pelvic fins, adding to their serpentine appearance. Their eyes are rather small; morays rely mostly on their highly developed sense of smell, lying in wait to ambush prey. The body is generally patterned. In some species, the inside of the mouth is also patterned. Their jaws are wide, framing a protruding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lionfish
''Pterois'' is a genus of venomous fish, venomous marine fish, commonly known as the lionfish, native to the Indo-Pacific. It is characterized by conspicuous aposematism, warning coloration with red or black bands and ostentatious dorsal fins tipped with venomous Spine (zoology), spines. ''Pterois radiata'', ''Pterois volitans'', and ''Pterois miles'' are the most commonly studied species in the genus. ''Pterois'' species are popular aquarium fish. ''P. volitans'' and ''P. miles'' are recent and significant invasive species in the west Atlantic, Caribbean Sea, and Mediterranean Sea. Taxonomy ''Pterois'' was described as a genus in 1817 by German natural history, naturalist, botany, botanist, biologist, and ornithology, ornithologist Lorenz Oken. In 1856, French naturalist Eugène Anselme Sébastien Léon Desmarest designated ''Scorpaena volitans'', which had been named by Marcus Elieser Bloch, Bloch in 1787 and which was the same as Linnaeus's 1758 ''Gasterosteus volitans'', as th ...

Micronesia
Micronesia (, ) is a subregion of Oceania, consisting of approximately 2,000 small islands in the Northwestern Pacific Ocean. It has a close shared cultural history with three other island regions: Maritime Southeast Asia to the west, Polynesia to the east, and Melanesia to the south—as well as with the wider community of Austronesian peoples. The region has a tropical marine climate and is part of the Oceanian realm. It includes four main archipelagos—the Caroline Islands, the Gilbert Islands, the Mariana Islands, and the Marshall Islands — as well as numerous islands that are not part of any archipelago. Political control of areas within Micronesia varies depending on the island, and is distributed among six sovereign nations. Some of the Caroline Islands are part of the Republic of Palau and some are part of the Federated States of Micronesia (often shortened to "FSM" or "Micronesia"—not to be confused with the identical name for the overall region).

Red Sea
The Red Sea is a sea inlet of the Indian Ocean, lying between Africa and Asia. Its connection to the ocean is in the south, through the Bab-el-Mandeb Strait and the Gulf of Aden. To its north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez—leading to the Suez Canal. It is underlain by the Red Sea Rift, which is part of the Great Rift Valley. The Red Sea has a surface area of roughly , is about long, and wide at its widest point. It has an average depth of , and in the central Suakin Trough, it reaches its maximum depth of . Approximately 40% of the Red Sea is quite shallow at less than deep and about 25% is less than deep. The extensive shallow shelves are noted for their marine life and corals. More than 1,000 invertebrate species and 200 types of soft and hard coral live in the sea. The Red Sea is the world's northernmost tropical sea and has been designated a Global 200 ecoregion.

Octopus
An octopus (: octopuses or octopodes) is a soft-bodied, eight-limbed mollusc of the order Octopoda (, ). The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, an octopus is bilaterally symmetric with two eyes and a beaked mouth at the centre point of the eight limbs. An octopus can radically deform its shape, enabling it to squeeze through small gaps. They trail their appendages behind them as they swim. The siphon is used for respiration and locomotion (by water jet propulsion). Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse invertebrates. Octopuses inhabit various ocean habitats, including coral reefs, pelagic waters, and the seabed; some live in the intertidal zone and others at abyssal depths. Most species grow quickly, mature early, and are short-lived. In most species, the male uses a speciall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crustaceans
Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of Arthropod, arthropods that are traditionally a part of the subphylum Crustacea (), a large, diverse group of mainly aquatic animal, aquatic arthropods including decapoda, decapods (shrimps, prawns, crabs, lobsters and crayfish), ostracoda, seed shrimp, branchiopoda, branchiopods, argulidae, fish lice, krill, remipedes, isopods, barnacles, copepods, Mysida, opossum shrimps, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the Hexapoda, hexapods (insects and entognathans) emerged deep in the Crustacean group, with the completed pan-group referred to as Pancrustacea. The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans (oligostracans and multicrustaceans). The 67,000 described spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgeonfish
Acanthuridae are a family (biology), family of ray-finned fish which includes surgeonfishes, tangs, and Naso (fish), unicornfishes. The family includes about 86 Extant taxon, extant species of ocean, marine fish living in tropical seas, usually around coral reefs. Many of the species are brightly colored and popular in aquarium, aquaria. Etymology and taxonomic history The name of the family is derived from the Greek words ''akantha'' and ''oura'', which loosely translate to "thorn" and "tail", respectively. This refers to the distinguishing characteristic of the family, the "scalpel" found on the caudal peduncle. In the early 1900s, the family was called Hepatidae. Subfamilies and genera Acanthuridae contains the following Neontology, extant subfamilies and genera: * Subfamily Nasinae Henry Weed Fowler, Fowler & Barton Appler Bean, Bean, 1929 ** Genus ''Naso (fish), Naso'' Bernard Germain de Lacépède, Lacépède, 1801 * Subfamily Acanthurinae Charles Lucien Bonaparte, Bonap ...
