Gerald R
Gerald is a masculine given name derived from the Germanic languages prefix ''ger-'' ("spear") and suffix ''-wald'' ("rule"). Gerald is a Norman French variant of the Germanic name. An Old English equivalent name was Garweald, the likely original name of Gerald of Mayo, a British Roman Catholic monk who established a monastery in Mayo, Ireland in 670. Nearly two centuries later, Gerald of Aurillac, a French count, took a vow of celibacy and later became known as the Roman Catholic patron saint of bachelors. The name was in regular use during the Middle Ages but declined after 1300 in England. It remained a common name in Ireland, where it was a common name among the powerful FitzGerald dynasty. The name was revived in the Anglosphere in the 19th century by writers of historical novels along with other names that had been popular in the medieval era. British novelist Ann Hatton published a novel called ''Gerald Fitzgerald'' in 1831. Author Dorothea Grubb published her nove ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Terapontidae
Grunters or tigerperches are ray-finned fishes in the family Terapontidae (also spelled Teraponidae, Theraponidae or Therapontidae). This family is part of the superfamily Percoidea of the order Perciformes. Characteristics The Terapontidae is a large family of small to medium-sized perciform fishes which occur in marine, brackish and fresh waters in the Indo-Pacific region. They are characterised by a single long-based dorsal fin which has a notch marking the boundary between the spiny and soft-rayed portions. They have small to moderate-sized scales, a continuous lateral line reaching the caudal fin, and most species lack teeth on the roof of the mouth. The marine species are found in inshore sea and brackish waters, some species are able to enter extremely saline and fresh waters. In Australia and New Guinea there are a number of species restricted to fresh water. Classification The following genera are classified within the family Terpontidae: * '' Amniataba'' Whitley ...

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Alligator Rivers
Alligator Rivers is the name of an area in an Arnhem Land region of the Northern Territory of Australia, containing three rivers, the East, West, and South Alligator Rivers. It is regarded as one of the richest biological regions in Australia, with part of the region in the Kakadu National Park. It is an Important Bird Area (IBA), lying to the east of the Adelaide and Mary River Floodplains IBA. It also contains mineral deposits, especially uranium, and the Ranger Uranium Mine is located there. The area is also rich in Australian Aboriginal art, with 1500 sites. The Kakadu National Park is one of the few World Heritage sites on the list because of both its natural and human heritage values. They were explored by Lieutenant Phillip Parker King in 1820, who named them in the mistaken belief that the crocodiles in the estuaries were alligators. Rivers The East Alligator River is about long. After rising in the northern part of the Arnhem Land Plateau, it flows with tributary s ...
