Holothuria Scabra
''Holothuria scabra'', or sandfish, is a species of sea cucumber in the family Holothuriidae. It was placed in the subgenus ''Metriatyla'' by Rowe in 1969 and is the type species of the subgenus. Sandfish are harvested and processed into "beche-de-mer" and eaten in China and other Pacific coastal communities. Sea cucumbers are marine invertebrates and are closely related to sea urchins and starfish. All these groups tend to have radial symmetry and have a water vascular system that operates by hydrostatic pressure, enabling them to move around by use of many suckers known as tube feet. Sea cucumbers are usually leathery, gherkin-shaped animals with a cluster of feeding tentacles at one end surrounding the mouth. Anatomy and morphology The sandfish has the same basic anatomy as most other species of sea cucumber. Their bodies are elongated and cylindric, and relatively stubby. Their dorsal side can range in color from a grey-brown to black, with darkened wrinkles across the bod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Persian Gulf
The Persian Gulf ( fa, خلیج فارس, translit=xalij-e fârs, lit=Gulf of Persis, Fars, ), sometimes called the ( ar, اَلْخَلِيْجُ ٱلْعَرَبِيُّ, Al-Khalīj al-ˁArabī), is a Mediterranean sea (oceanography), mediterranean sea in Western Asia. The body of water is an extension of the Indian Ocean located between Iran and the Arabian Peninsula.United Nations Group of Experts on Geographical NameWorking Paper No. 61, 23rd Session, Vienna, 28 March – 4 April 2006. accessed October 9, 2010 It is connected to the Gulf of Oman in the east by the Strait of Hormuz. The Shatt al-Arab river delta forms the northwest shoreline. The Persian Gulf has many fishing grounds, extensive reefs (mostly rocky, but also Coral reef, coral), and abundant pearl oysters, however its ecology has been damaged by industrialization and oil spills. The Persian Gulf is in the Persian Gulf Basin, which is of Cenozoic origin and related to the subduction of the Arabian Plate u ...

Fauna Of The Pacific Ocean
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as ''Biota (ecology), biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontology, Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna of Madagascar, Fauna'' comes from the name Fauna (deity), Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan (god), Pan, and ''panis'' is the Greek language, Greek equivalent of fauna. ''Fauna'' is also ...

Worm Pearlfish
The worm pearlfish (''Encheliophis vermicularis'') is an eel-like fish in the family Carapidae. Description The worm pearlfish is typically 15 cm long and is characterized by its long, slender body and lack of scales. Morphology Worm pearlfish lack the pectoral or pelvic fins that are common characters of the family ''Carapidae''. The upper half of its body is blackish-pinkish in color and its underside is silver. Its tail is black and tapered. Compared to other members of the family ''Carapidae'', the worm pearlfish has a relatively weak jaw. The maxillaries and premaxillaries in worm pearlfishes are joined by short connective fibers in the small mouth opening. Both the maxillaries and premaxillaries are connected to the fish's skin, which creates a small mouth opening. Worm pearlfishes’ mouths are smaller and weaker than mouths of pearlfishes in other genera because they feed on soft, unresisting food in a confined space, as opposed to swift-moving, unconstrained p ...

Kappaphycus
''Kappaphycus'' is a genus of red algae. Species are distributed in the waters of East Africa, Indonesia, Malaysia, Hainan Island, the Philippines, and Micronesia.Guiry, M. D. In: Guiry, M. D. & G. M. Guiry. 2013''Kappaphycus''.AlgaeBase. National University of Ireland, Galway. Accessed 07 November 2013. Genus ''Kappaphycus'' is "morphologically plastic", with few visible characters that can be used to separate the taxa, so distinguishing the species can be difficult. In addition, many commercial varieties have been bred. Molecular analyses can be used. In general, these algae have fleshy thalli that grow erect from one or more anchors. The longest individuals can exceed a meter in length. All species produce kappa-carrageenan. Farming of this is a large business in the Philippines. Gavino Trono is a Filipino biologist dubbed the “Father of Kappaphycus farming”. ''Kappaphycus alvarezii'' is widely cultivated as a raw source of carrageenan, and other species are used, as well ...

Penaeus Monodon
''Penaeus monodon'', commonly known as the giant tiger prawn, Asian tiger shrimp, black tiger shrimp, and other names, is a marine crustacean that is widely reared for food. Taxonomy ''Penaeus monodon'' was alpha taxonomy, first described by Johan Christian Fabricius in 1798. That name was overlooked for a long time, until 1949 when Lipke Holthuis clarified to which species it referred. Holthuis also showed that ''P. monodon'' had to be the type species of the genus ''Penaeus''. Description Females can reach about long, but are typically long and weigh ; males are slightly smaller at long and weighing . The carapace and abdomen are transversely banded with alternative red and white. The antennae are grayish brown. Brown pereiopods and pleopods are present with fringing setae in red. Distribution Its natural distribution is the Indo-Pacific, ranging from the eastern coast of Africa and the Arabian Peninsula, as far as Southeast Asia, the Pacific Ocean, and northern Aust ...

Trepanging
Trepanging is the act of collection or harvesting of sea cucumbers, known in Indonesian as ''trepang'', Malay těripang, and used as food. The collector, or fisher, of ''trepang'' is a trepanger. Trepanging is comparable to clamming, crabbing, lobstering, musseling, shrimping and other forms of "fishing" whose goal is the acquisition of edible invertebrates rather than fish. History To supply the markets of Southern China, Makassarese trepangers traded with the Aboriginal Australians of Arnhem Land from at least the 18th century or likely prior. This Makassan contact with Australia is the first recorded example of interaction between the inhabitants of the Australian continent and their Asian neighbours. This contact had a major impact on the Indigenous Australians. The Makassarese exchanged goods such as cloth, tobacco, knives, rice and alcohol for the right to trepang coastal waters and employ local labour. Makassar pidgin became a ''lingua franca'' along the north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seagrass Meadow
A seagrass meadow or seagrass bed is an underwater ecosystem formed by seagrasses. Seagrasses are marine (saltwater) plants found in shallow coastal waters and in the brackish waters of estuaries. Seagrasses are flowering plants with stems and long green, grass-like leaves. They produce seeds and pollen and have roots and rhizomes which anchor them in seafloor sand. Seagrasses form dense underwater meadows which are among the most productive ecosystems in the world. They provide habitats and food for a diversity of marine life comparable to that of coral reefs. This includes invertebrates like shrimp and crabs, cod and flatfish, marine mammals and birds. They provide refuges for endangered species such as seahorses, turtles, and dugongs. They function as nursery habitats for shrimps, scallops and many commercial fish species. Seagrass meadows provide coastal storm protection by the way their leaves absorb energy from waves as they hit the coast. They keep coastal waters healthy ...
