John Ernest Randall
John Ernest "Jack" Randall (May 22, 1924 – April 26, 2020) was an American ichthyologist and a leading authority on coral reef fishes. Randall described over 800 species and authored 11 books and over 900 scientific papers and popular articles. He spent most of his career working in Hawaii. He died in April 2020 at the age of 95. Career John Ernest Randall was born in Los Angeles, California in May 1924, to John and Mildred (McKibben) Randall.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Soleidae
The true soles are a family, Soleidae, of flatfishes. It includes saltwater and brackish water species in the East Atlantic, Indian Ocean, and West and Central Pacific Ocean. Freshwater species are found in Africa, southern Asia, New Guinea, and Australia. In the past, soles of the Americas (both fresh and salt water) were included in this family, but they have been separated to their own family, the American soles (Achiridae). The only true sole remaining in that region is ''Aseraggodes herrei'' of the Galápagos and Cocos Island. The true soles are bottom-dwelling fishes feeding on small crustaceans and other invertebrates. The family contains 30 genera and a total of about 180 species. Soles begin life as bilaterally symmetric larvae, with an eye on each side of the head, but during development, the left eye moves around onto the right side of the head. Adult soles lie on their left (blind) sides on the sea floor, often covered in mud, which in combination with their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brackish
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific ...

New Guinea
New Guinea (; Hiri Motu: ''Niu Gini''; id, Papua, or , historically ) is the world's second-largest island with an area of . Located in Oceania in the southwestern Pacific Ocean, the island is separated from Australia by the wide Torres Strait, though both landmasses lie on the same continental shelf. Numerous smaller islands are located to the west and east. The eastern half of the island is the major land mass of the independent state of Papua New Guinea. The western half, known as Western New Guinea, forms a part of Indonesia and is organized as the provinces of Papua, Central Papua, Highland Papua, South Papua, Southwest Papua, and West Papua. The largest cities on the island are Jayapura (capital of Papua, Indonesia) and Port Moresby (capital of Papua New Guinea). Names The island has been known by various names: The name ''Papua'' was used to refer to parts of the island before contact with the West. Its etymology is unclear; one theory states that ...

Max Carl Wilhelm Weber
Max Carl Wilhelm Weber van Bosse or Max Wilhelm Carl Weber (5 December 1852, in Bonn – 7 February 1937, in Eerbeek) was a German- Dutch zoologist and biogeographer. Weber studied at the University of Bonn, then at the Humboldt University in Berlin with the zoologist Eduard Carl von Martens (1831–1904). He obtained his doctorate in 1877. Weber taught at the University of Utrecht then participated in an expedition to the Barents Sea. He became Professor of Zoology, Anatomy and Physiology at the University of Amsterdam in 1883. In the same year he received naturalised Dutch citizenship. His discoveries as leader of the Siboga Expedition led him to propose Weber's line, which encloses the region in which the mammalian fauna is exclusively Australasian, as an alternative to Wallace's Line. As is the case with plant species, faunal surveys revealed that for most vertebrate groups Wallace’s line was not the most significant biogeographic boundary. The Tanimbar Island g ...
