Calamus Calamus
The saucereye porgy (''Calamus calamus'') is an ocean-going species of fish in the family Sparidae. In Bermuda, they are also known as the goat's head porgy. In Jamaica, they are known as the Porgi grunt and the sugareye porgy. They may also be known simply by the name Porgy in several other Caribbean islands. Saucereye porgies are considered to be minor gamefishes and when caught are marketed both fresh and frozen. Taxonomy and naming The Saucereye porgy was first described by the French zoologist, Achille Valenciennes in a 22-volume work entitled ''Histoire naturelle des poissons'' (Natural History of Fishes), which was a collaboration with fellow zoologist, Georges Cuvier. It was first described as ''Pagellus calamus'', being placed in the genus ''Pagellus''. It was since moved into ''Calamus'', this name means "quill", in an allusion to what William Swainson described as “the second anal-fin spine, hollow, shaped as a pen" when he proposed the genus '' Calamus''.

Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoology, zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "''Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pagellus
''Pagellus'' is a genus of marine ray-finned fish belonging the family (biology), family Sparidae, which includes the seabreams and porgies. These fishes are found in the eastern Atlantic Ocean, the Mediterranean Sea and the western Indian Ocean. Taxonomy ''Pagellus'' was first proposed as a genus in 1830 by the French zoologist Achille Valenciennes. The type species was subsequently designated as ''Sparus erythrinus'' by Eugène Anselme Sébastien Léon Desmarest in 1856. Linnaeus Species description, described ''S. erythrinus'' in the 10th edition of Systema Naturae, 10th edition of ''Systema Naturae'' with its Type locality (biology), type locality given as the Mediterranean and America. This genus is placed in the family Sparidae within the Order (biology), order Spariformes by the 5th edition of ''Fishes of the World''. Some authorities classify this genus in the subfamily Pagellinae, but the 5th edition of Fishes of the World does not recognise subfamilies within the Sparida ...

Sea Grass
Seagrasses are the only flowering plants which grow in marine (ocean), marine environments. There are about 60 species of fully marine seagrasses which belong to four Family (biology), families (Posidoniaceae, Zosteraceae, Hydrocharitaceae and Cymodoceaceae), all in the order Alismatales (in the clade of monocotyledons). Seagrasses evolved from terrestrial plants which recolonised the ocean 70 to 100 million years ago. The name ''seagrass'' stems from the many species with long and narrow Leaf, leaves, which grow by rhizome extension and often spread across large "Seagrass meadow, meadows" resembling grassland; many species superficially resemble terrestrial grasses of the family Poaceae. Like all autotrophic plants, seagrasses photosynthesize, in the submerged photic zone, and most occur in shallow and sheltered coastal waters anchored in sand or mud bottoms. Most species undergo submarine pollination and complete their life cycle underwater. While it was previously believed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scuba Diving
Scuba diving is a Diving mode, mode of underwater diving whereby divers use Scuba set, breathing equipment that is completely independent of a surface breathing gas supply, and therefore has a limited but variable endurance. The word ''scuba'' is an Acronym#Normal case and acronyms, acronym for "Self-Contained Underwater Breathing Apparatus" and was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, affording them greater independence and movement than surface-supplied divers, and more time underwater than freedivers. Although the use of compressed air is common, other gas blends are also used. Open-circuit scuba systems discharge the breathing gas into the environment as it is exhaled and consist of one or more diving cylinders containing breathing gas at high pressure which is supplied to the diver at ambient pressure through a diving regulator. They may include additional cylinders for range extension, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ...
