Argonauta Hians
''Argonauta hians'', also known as the winged argonaut, muddy argonaut or brown paper nautilus, is a species of pelagic octopus. The common name comes from the grey to brown coloured shell. The Chinese name for this species translates as "grey sea-horse's nest". The female of the species, like all argonauts, creates a paper-thin eggcase that coils around the octopus much like the way a nautilus lives in its shell (hence the name paper nautilus). The eggcase is characterised by a wide keel that gives it a square appearance, few rounded tubercles along the keel, and less than 40 smooth ribs across the sides of the shell. The shell is usually approximately 80 mm in length, although it can exceed 120 mm in exceptional specimens; the world record size is 121.5 mm. ''A. hians'' is cosmopolitan, occurring in tropical and subtropical waters worldwide. It is an extremely variable species and there appear to exist at least two distinct forms; a "southern" form and "norther ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mergui Archipelago
The Mergui Archipelago (also Myeik Archipelago or ''Myeik Kyunzu''; ) is located in far southern Myanmar (Burma) and is part of the Tanintharyi Region. It consists of around 800 islands, varying in size from very small to hundreds of square kilometres, all lying in the Andaman Sea off the western shore of the Malay Peninsula near its landward (northern) end where it joins the rest of Indochina. They are occasionally referred to as the Pashu Islands because the Malay inhabitants are locally called ''Pashu''. Environment Geologically, the islands are characterized mainly by limestone and granite. They are generally covered with thick tropical growth, including rainforest, and their shorelines are punctuated by beaches, rocky headlands, and in some places, mangrove swamps. Offshore are extensive coral reefs. The archipelago's virtual isolation from most of mankind's influence on the natural environment has given the islands and the surrounding waters of the Andaman Sea a great ...

Jellyfish
Jellyfish, also known as sea jellies or simply jellies, are the #Life cycle, medusa-phase of certain gelatinous members of the subphylum Medusozoa, which is a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals, although a few are anchored to the seabed by stalks rather than being motile. They are made of an umbrella-shaped main body made of mesoglea, known as the ''bell'', and a collection of trailing tentacles on the underside. Via pulsating contractions, the bell can provide propulsion for animal locomotion, locomotion through open water. The tentacles are armed with cnidocyte, stinging cells and may be used to capture prey or to defend against predators. Jellyfish have a complex biological life cycle, life cycle, and the medusa is normally the sexual phase, which produces planula larvae. These then disperse widely and enter a sedentary #Life cycle, polyp phase which may include asexual budding before reaching sexual maturity. Jellyfish ...

Phyllorhiza Punctata
''Phyllorhiza punctata'' is a species of jellyfish, also known as the floating bell, Australian spotted jellyfish, brown jellyfish or the white-spotted jellyfish. It is native to the western Pacific from Australia to Japan, but has been introduced widely elsewhere. It feeds primarily on zooplankton. ''P. punctata'' generally can reach up to in bell diameter, but in October 2007, one wide, perhaps the largest ever recorded, was found on Sunset Beach, North Carolina. Description True jellyfish go through a two-stage life cycle which consists of a medusa stage (adult) and a polyp stage (juvenile). In the medusa stage, male jellyfish release sperm into the water column and the female jellyfish gathers the sperm into her mouth where she holds the eggs. Once fertilization occurs and larvae are formed they leave their mother and settle to the ocean floor. Once on the bottom a polyp form occurs and this form reproduces asexually by "cloning" or dividing itself into other polyps. ...

Argonauta Argo
''Argonauta argo'', also known as the greater argonaut, is a species of pelagic octopus belonging to the genus ''Argonaut (animal), Argonauta''. The Chinese name for this species translates as "white sea-horse's nest". ''A. argo'' was the first argonaut species to be described and is consequently the type species of the genus. The type specimen of ''A. argo'' was collected in the Mediterranean Sea and is deposited at the Linnean Society of London. Description ''A. argo'' is the largest species in the genus and also produces the largest eggcase. Live animals have a characteristic blue sheen on the first cephalopod arm, arm pair and around the cephalopod eye, eyes. The eggcase is characterised by two rows of small, sharp tubercles running along a narrow keel, smooth ribs across the walls of the shell, and a thickening along the shell aperture, which forms distinct protrusions or 'horns' on either side.

Alepisaurus Ferox
''Alepisaurus ferox'', also known as the long snouted lancetfish, longnose lancetfish, or cannibal fish, is a species of lancetfish found in the ocean depths down to 1,830 m (6,000 ft). This species grows to in total length and a weight of . The appellation ''cannibal fish'' stems from discoveries of partially-digested conspecifics in captured specimens. Habitat and ecosystem Habitat ''A. ferox'' lives in deep water oceans in the Western and Eastern Pacific, from the Aleutian Islands to Chile; the Western Atlantic, from the Gulf of Maine to the Gulf of Mexico, including the Caribbean Sea; in addition to the Northwest & Eastern Atlantic, Indian Ocean and China Sea. The longnose lancetfish can also be found as far north as Russia. This expansive geographic reach has caused for the species to be accidentally caught by some tuna fisheries. Daily vertical migrations from the epipelagic all the way down to the mesopelagic or bathypelagic zones are undertaken to find food ...

Heteropod
The Pterotracheoidea is, according to the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), a taxonomic superfamily of sea snails or sea slugs, marine gastropod molluscs in the clade Littorinimorpha. They are commonly called heteropods or sea elephants. Taxonomy According to the World Registry of Marine Species, this superfamily comprises five families, two of which are extinct: Habitat These holoplanktonic snails are found floating or swimming in tropical to subtropical open oceans and seas at a depth of maximum 200 to 300 m Anatomy These snails have adapted themselves to a pelagic living : * a transparent body and shell * the foot has evolved into a swimming fin that produces motion through undulation. * the proboscis is mobile and can be extended giving it a trunk-like appearance (giving rise to their common name : sea elephants). The taenioglossate radula, situated at the tip of the proboscis, can be protruded to capture the prey. They have paired, large sp ...

Mollusc
Mollusca is a phylum of protostome, protostomic invertebrate animals, whose members are known as molluscs or mollusks (). Around 76,000 extant taxon, extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and the proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine biology, marine phylum, comprising about 23% of all the named marine organisms. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat, as numerous groups are freshwater mollusc, freshwater and even terrestrial molluscs, terrestrial species. The phylum is typically divided into 7 or 8 taxonomy (biology), taxonomic class (biology), classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurobiology, neurologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
