Pseudorhombus Arsius
''Pseudorhombus arsius'', the largetooth flounder, is a species of left-eyed flatfish, that is the dark side with the eyes on the adult fish is the left side of the fish's body, from the family Paralichthyidae. As ''Rhombus polyspilos'' it was named as the type species of the genus '' Pseudorhombus''. It is an Indo-Pacific species and is fished for by both recreational and commercial fisheries. Description ''Pseudorhombus arsius'' has an oval-shaped body which has a depth which is 1.8 to 2.3 times its standard length. The head has a slight notch in front of upper eye. The eyes are on the left side and have a diameter which is a fifth of the length of the head and the snout has a length equal to or slightly greater than the diameter of the eye. The dorsal fin starts in front of its upper eye and of the nostrils on blind side. The mouth forms a deep cleft with the maxilla normally almost half the length of the head. The jaws and teeth are nearly equally developed on both jaws. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Buchanan-Hamilton
Francis Buchanan (15 February 1762 – 15 June 1829), later known as Francis Hamilton but often referred to as Francis Buchanan-Hamilton, was a Scottish physician who made significant contributions as a geographer, zoologist, and botanist while living in India. He did not assume the name of Hamilton until three years after his retirement from India. The standard botanical author abbreviation Buch.-Ham. is applied to plants and animals he described, though today the form "Hamilton, 1822" is more usually seen in ichthyology and is preferred by Fishbase. Early life Francis Buchanan was born at Bardowie, Callander, Perthshire where Elizabeth, his mother, lived on the estate of Branziet; his father Thomas, a physician, came in Spittal and claimed the chiefdom of the name of Buchanan and owned the Leny estate. Francis Buchanan matriculated in 1774 and received an MA in 1779. As he had three older brothers, he had to earn a living from a profession, so Buchanan studied medicine ...

Anal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...

Fish Of The Pacific Ocean
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...

Hooghly River
The Bhagirathi Hooghly River (Anglicized alternatively spelled ''Hoogli'' or ''Hugli'') or the 'Bhāgirathi-Hooghly', called the Ganga or the Kati-Ganga in mythological texts, is the eastern distributary of the Ganges River in West Bengal, India, rising close to Giria in Murshidabad. The main distributary of the Ganges then flows into Bangladesh as the Padma. Today there is a man-made canal called the Farakka Feeder Canal connecting the Ganges to the Bhagirathi. The river flows through the Rarh region, the lower deltaic districts of West Bengal, and eventually into the Bay of Bengal. The upper riparian zone of the river is called Bhagirathi while the lower riparian zone is called Hooghly. Major rivers that drain into the Bhagirathi-Hooghly include Mayurakshi, Jalangi , Ajay, Damodar, Rupnarayan and Haldi rivers other than the Ganges. Hugli-Chinsura, Bandel, Chandannagar, Srirampur, Barrackpur, Rishra, Uttarpara, Titagarh, Kamarhati, Agarpara, Baranagar and Kolkata are loc ...

Benthic
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from ancient Greek, βένθος (bénthos), meaning "the depths." Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at the shore line (intertidal ...

Bass Strait
Bass Strait () is a strait separating the island state of Tasmania from the Australian mainland (more specifically the coast of Victoria, with the exception of the land border across Boundary Islet). The strait provides the most direct waterway between the Great Australian Bight and the Tasman Sea, and is also the only maritime route into the economically prominent Port Phillip Bay. Formed 8,000 years ago by rising sea levels at the end of the last glacial period, the strait was named after English explorer and physician George Bass (1771-1803) by European colonists. Extent The International Hydrographic Organization defines the limits of Bass Strait as follows: :''On the west.'' The eastern limit of the Great Australian Bight eing a line from Cape Otway, Australia, to King Island (Tasmania)">King Island and thence to Cape Grim, the northwest extreme of Tasmania]. :''On the east.''

Fiji
Fiji ( , ,; fj, Viti, ; Fiji Hindi: फ़िजी, ''Fijī''), officially the Republic of Fiji, is an island country in Melanesia, part of Oceania in the South Pacific Ocean. It lies about north-northeast of New Zealand. Fiji consists of an archipelago of more than 330 islands—of which about 110 are permanently inhabited—and more than 500 islets, amounting to a total land area of about . The most outlying island group is Ono-i-Lau. About 87% of the total population of live on the two major islands, Viti Levu and Vanua Levu. About three-quarters of Fijians live on Viti Levu's coasts: either in the capital city of Suva; or in smaller urban centres such as Nadi—where tourism is the major local industry; or in Lautoka, where the Sugarcane, sugar-cane industry is dominant. The interior of Viti Levu is sparsely inhabited because of its terrain. The majority of Fiji's islands were formed by Volcano, volcanic activity starting around 150 million years ago. Some geo ...

Knysna
Knysna () is a town with 76,150 inhabitants (2019 mid-year estimates) in the Western Cape province of South Africa. and is one of the destinations on the loosely defined Garden Route tourist route. It lies at 34° 2' 6.3168'' S and 23° 2' 47.2884'' E., and is situated 60 kilometres east of the city of George on the N2 highway, and 33 kilometres west of the Plettenberg Bay on the same road. History Early history Forty fossilised hominid footprints, dating to about 90,000 years ago, along with various other archaeological discoveries suggest that humans have lived in Knysna for well over 300,000 years. The first of these were various San Hunter-gatherer peoples who inhabited most of Southern Africa in paleolithic. The San were gradually displaced and absorbed by south migrating Khoekhoe peoples. Houtunqua (Outeniqua) Khoe The indigenous inhabitants of the Knysna area are a southern Khoekhoe people called the Houtunqua or Outeniqua. Their name means "The People Who Bear Honey" ...

Algoa Bay
Algoa Bay is a maritime bay in the Eastern Cape, South Africa. It is located in the east coast, east of the Cape of Good Hope. Algoa Bay is bounded in the west by Cape Recife and in the east by Cape Padrone. The bay is up to deep. The harbour city of Port Elizabeth is situated adjacent to the bay, as is the Port of Ngqura deep water port facility. History The Portuguese explorer Bartolomeu Dias was the first European to reach Algoa Bay in 1488, where he planted a wooden cross on a small island now called St Croix or Santa Cruz island. He gave the bay a name meaning "Bay of the Rock", which was changed in Portugal to ''Bahia de Lagoa'' or Bay of the Lagoon, and which eventually became Algoa Bay. Joshua Slocum talks about Algoa Bay in his book 'Sailing Alone Around the World' (this is not an historical account): Nautical charts of the bay caution mariners that "projectiles and badly corroded mustard gas containers have been found in the area between Cape St Francis and Bir ...
