Pegasus Lancifer
''Pegasus lancifer'', the sculptured seamoth or sculptured dragonfish, is a species of fish in the family Pegasidae which is endemic to the temperate seas of southern Australia and Tasmania. They are known to gather in large numbers in the shallows of estuaries. Individuals can bury themselves in the sediment and change colours to camouflage them. The male & female spawn as a pair, swimming with their vents touching around a above the substrate, while the eggs and sperm are released. After spawning the pair separates and the eggs begin a pelagic The pelagic zone consists of the water column of the open ocean, and can be further divided into regions by depth (as illustrated on the right).

Johann Jakob Kaup
Johann Jakob von Kaup (10 April 1803 – 4 July 1873) was a German naturalist. A proponent of natural philosophy, he believed in an innate mathematical order in nature and he attempted biological classifications based on the Quinarian system. Kaup is also known for having coined popular prehistoric taxa like '' Pterosauria'' and ''Machairodus''. Biography He was born at Darmstadt. After studying at Göttingen and Heidelberg he spent two years at Leiden, where his attention was specially devoted to the amphibians and fishes. He then returned to Darmstadt as an assistant in the grand ducal museum, of which in 1840 he became inspector. In 1829 he published ''Skizze zur Entwickelungsgeschichte der europäischen Thierwelt'', in which he regarded the animal world as developed from lower to higher forms, from the amphibians through the birds to the beasts of prey; but subsequently he repudiated this work as a youthful indiscretion, and on the publication of Darwin's ''Origin of Species' ...

Fish
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. Mos ...

Pegasidae
The seamoths make up a family of fishes, the Pegasidae, within the order Syngnathiformes. They are named for Pegasus, a creature from Greek mythology. Seamoths are notable for their unusual appearance, including flattened bodies, the presence of large, wing-like, pectoral fins, a long snout, and a body encased in thick, bony plates. They are found primarily in coastal tropical waters of the Indo-Pacific. Biology Seamoths have modified pelvic fins that allow them to "walk" across the sea bottom where they live. Their jaws are ventral, located behind their long rostrum, and are toothless. Their mouth is highly specialized, and can form a tube-like mouth used to suck worms and other small invertebrates from their burrows. They periodically molt their skin, perhaps as often as every five days.Herold D, and Clark E. 1993. Monogamy, spawning, and skin-shedding of the seamoth, ''Eurypegasus draconis'' (Pisces: Pegasidae).

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pelagic
The pelagic zone consists of the water column of the open ocean, and can be further divided into regions by depth (as illustrated on the right). The word ''pelagic'' is derived . The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom. Conditions in the water column change with depth: pressure increases; temperature and light decrease; salinity, oxygen, micronutrients (such as iron, magnesium and calcium) all change. Marine life is affected by bathymetry (underwater topography) such as the seafloor, shoreline, or a submarine seamount, as well as by proximity to the boundary between the ocean and the atmosphere at the ocean surface, which brings light for photosynthesis, predation from above, and wind stirring up waves and setting currents in motion. The pelagic zone refers to the open, free waters away from the shore, where marine life can swim freely in any direction unhindered by topographical constraints. Th ...

Pegasus (fish)
''Pegasus'' is a genus of seamoths found in coastal tropical marine waters. The name was taken from the winged horse Pegasus in Greek mythology. This horse was created with Medusa´s blood. The member species are distributed in the Indo-West Pacific Ocean waters around: Australia, Bahrain, China, India, Indonesia, Japan, Malaysia, Mozambique, Myanmar, the Philippines, Saudi Arabia, Singapore, Taiwan, Tanzania and Thailand. Species There are currently 5 recognized species in this genus: * '' Pegasus lancifer'' Kaup, 1861 (Sculptured seamoth) * '' Pegasus laternarius'' G. Cuvier, 1816 (Brick seamoth) * ''Pegasus volitans'' Linnaeus, 1758 (Long-tail seamoth) * '' Pegasus tetrabelos'' Osterhage, Pogonoski, Appleyard & W. T.

Taxa Named By Johann Jakob Kaup
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
