Assessor Randalli
''Assessor randalli'', Randall's assessor or Randall's devilfish, is a species of ray-finned fish belonging to the family Plesiopidae, the longfins or roundheads. It is found in the western Pacific Ocean, mainly in the seas around Japan and Taiwan. It is a similar species to ''Assessor macneilli'' but it is slightly brighter in colour and has more rounded rounder fins which have with yellow markings, there are also yellow markings on its body. They are associated with crevices and gullies in reefs, where they hover at the entrances to caves and holes. They are mouthbrooders, the male guards the eggs by keeping them in his mouth until they hatch. They are rare in the Aquarium trade but have been bred in captivity. The specific name honours the ichthyologist John Ernest Randall of the Bishop Museum in Honolulu, who collected the type specimen In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of th ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Family (biology)
Family ( la, familia, plural ') 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". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Plesiopidae
The longfins, also known as roundheads or spiny basslets, are a family, Plesiopidae, which were formerly placed in the order Perciformes but are now regarded as being ''incertae sedis'' in the subseries Ovalentaria in the clade Percomorpha. 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 '' Pa ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Assessor Macneilli
''Assessor macneilli'', the blue devilfish or blue scissortail, is a fish from the southwest Pacific Ocean. It occasionally makes its way into the aquarium trade. It grows to in length. It is purple-blue with long fins. Description ''Assessor macneilli'' is a dark blue fish which has a thin paler blue edge on the dorsal, anal, and pelvic fins. The dorsal fin has 11 spines and 8-10 rays, the anal fin has 3 spines and 9-10 rays and the pectoral fins have 14-16 rays. Distribution The blue devilfish is found in the western Pacific Ocean from north eastern Australia and New Guinea, through the Great Barrier Reef and the Coral Sea to New Caledonia. Habitat and biology ''Assessor macneilli'' is found on reefs at depths of , where it can group together in shoals of up 100 fishes in caves, crevices and under ledges, where they often swim upside down. It is a plankton feeder and its main food are crustaceans such as copepods, ostracods and amphipods. It is a mouthbrooder and the mal ...

Mouthbrooding
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. Although mouthbrooding is performed by a variety of different animals, such as the Darwin's frog, fish are by far the most diverse mouthbrooders. Mouthbrooding has evolved independently in several different families of fish. Mouthbrooding behaviour Paternal mouthbrooders are species where the male looks after the eggs. Paternal mouthbrooders include the arowana, various mouthbrooding bettas and gouramies such as ''Betta pugnax'', and sea catfish such as ''Ariopsis felis''. Among cichlids, paternal mouthbrooding is relatively rare, but is found among some of the tilapiines, most notably the black-chin tilapia ''Sarotherodon melanotheron''. In the case of the maternal mouthbrooders, the female takes the eggs. Maternal mouthbrooders are found among both African and South American ci ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Ichthyology
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish ( Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). According to FishBase, 33,400 species of fish had been described as of October 2016, with approximately 250 new species described each year. Etymology The word is derived from the Greek words ἰχθύς, ''ikhthus'', meaning "fish"; and λογία, ''logia'', meaning "to study". History The study of fish dates from the Upper Paleolithic Revolution (with the advent of "high culture"). The science of ichthyology was developed in several interconnecting epochs, each with various significant advancements. The study of fish receives its origins from humans' desire to feed, clothe, and equip themselves with useful implements. According to Michael Barton, a prominent ichthyologist and professor at Centre College, "the earliest ichthyologists were ''hunters and gatherers'' who had learned how to obtain the most use ...
