Gilbert Percy Whitley
Gilbert Percy Whitley (9 June 1903 – 18 July 1975) was a British-born Australian ichthyologist and malacologist who was curator of fishes at the Australian Museum in Sydney for about 40 years. Early life and education Gilbert Percy Whitley was born on 9 June 1903 at Swaythling, Southampton, England, the eldest child of Percy Nathan Whitley and Clara Minnie (née Moass). He was educated first at King Edward VI School, Southampton and then Osborne House School in Romsey, Hampshire. Whitley migrated with his family to Sydney Sydney is the capital city of the States and territories of Australia, state of New South Wales and the List of cities in Australia by population, most populous city in Australia. Located on Australia's east coast, the metropolis surrounds Syd ... in 1921.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 taxonomy (biology), 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. Phylogeneti ...

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 ...

Longfin
The longfins, also known as roundheads or spiny basslets, are a family, Plesiopidae, which were formerly placed in the order Perciformes or considered indeterminate percomorphs, but are now considered basal blenniiforms. They are elongated fishes, found in the Indian Ocean and western Pacific Ocean. Classification In some classifications, the genus ''Notograptus'' is split in its own family, Notograptidae, but FishBase is followed here. There are two subfamilies within the Plesiopidae and the genera are as follows: *Subfamily Acanthoclininae Günther, 1861 ** Genus ''Acanthoclinus'' Jenyns, 1841 ** Genus ''Acanthoplesiops'' Regan, 1912 ** Genus '' Beliops'' Hardy, 1985 ** Genus ''Belonepterygion'' McCulloch, 1915 ** Genus ''Notograptus'' Günther, 1867 * Subfamily Plesiopinae Günther, 1861 ** Genus '' Assessor'' Whitley, 1935 ** Genus ''Calloplesiops'' Fowler and Bean, 1930 ** Genus ''Fraudella'' Whitley, 1935 ** Genus ''Paraplesiops ''Pa ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Assessor Flavissimus
''Assessor flavissimus'', the yellow devilfish or yellow scissortail, is a fish from the western Central Pacific, recorded from the Great Barrier Reef and Papua New Guinea. It occasionally makes its way into the aquarium trade. It grows to a size of in length. It is bright yellow in colour and has a reddish-orange stripe running from the eye to the upper edge of the operculum, and a reddish-orange band on the dorsal and anal fins which is parallel to the fin margin. This species feeds on plankton and forms small groups under overhangs and ledges and in crevices, often swimming upside down. The males mouthbrood Mouthbrooding, also known as oral incubation and buccal incubation, is the care given by some groups of animals to their offspring by holding them in the mouth of the parent for extended periods of time.

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 ...
