Platycephalus Caeruleopunctatus
''Platycephalus caeruleopunctatus'', the bluespotted flathead, drift flathead, Eastern blue-spot flathead, longnose flathead, red flathead, red spotted flathead, sand flathead or yank, is a species of predatory ray-finned fish belonging to the family Platycephalidae, the flatheads. Bluespotted flathead are a marine species and are predominantly found in offshore waters and coastal bays on the east coast of Australia where they are almost exclusively found on marine sand. Ecology Flatheads are notable for their unusual body shape, upon which their hunting strategy is based. Flathead are dorsally compressed, meaning their body is wide but flattened and very low in height. Both eyes are on the top of the flattened head, giving excellent binocular vision to attack overhead prey. The effect is somewhat similar to flounder Flounders are a group of flatfish species. They are demersal fish, found at the bottom of oceans around the world; some species will also enter estuaries. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allan Riverstone McCulloch
Allan Riverstone McCulloch (20 June 1885 – 1 September 1925) was a prominent Australian ichthyologist. Born in Sydney, Australia, McCulloch began his scientific career at the age of 13 as an unpaid assistant to Edgar Ravenswood Waite in the Australian Museum where Waite encouraged McCulloch to study zoology. Three years later, he was employed as a "mechanical assistant", and five years after that, as curator of fishes, a post he held until his death. McCulloch collected and published prolifically; from his first paper in 1906 (published in ''Records of the Australian Museum''), no year passed without his making a contribution to science, and he wrote over 100 original papers in all, many including his own illustrations. McCulloch travelled widely for his collections, including trips to Queensland, Lord Howe Island, New Guinea, the Great Barrier Reef and various Pacific islands. His major research interest was in fish, but he was also given the responsibility of the crustace ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Platycephalidae
The Platycephalidae are a family of marine fish, most commonly referred to as flatheads. They are relatives of the popular lionfish, belonging to the order Scorpaeniformes. Taxonomy Platycephalidae was first proposed as a family in 1839 by the English naturalist William John Swainson. The 5th edition of ''Fishes of the World'' classifies this family within the suborder Platycephaloidei in the order Scorpaeniformes. Other authorities differ and do not consider the Scorpaeniformes to be a valid order because the Perciformes is not monophyletic without the taxa within the Scorpaeniformes being included within it. These authorities consider the Platycephalidae to belong to the suborder Platycephaloidei, along with the families Bembridae, Parabembridae, Hoplichthyidae and Plectrogeniidae within the Perciformes. Genera Platycephalidae has the following genera classified within it: Platycephalidae has been divided into as many as 5 subfamilies by some authors but Fishes of the Wor ...

Marine Life
Marine life, sea life, or ocean life is the plants, animals and other organisms that live in the salt water of seas or oceans, or the brackish water of coastal estuaries. At a fundamental level, marine life affects the nature of the planet. Marine organisms, mostly microorganisms, produce oxygen and sequester carbon. Marine life in part shape and protect shorelines, and some marine organisms even help create new land (e.g. coral building reefs). Most life forms evolved initially in marine habitats. By volume, oceans provide about 90% of the living space on the planet. The earliest vertebrates appeared in the form of fish, which live exclusively in water. Some of these evolved into amphibians, which spend portions of their lives in water and portions on land. One group of amphibians evolved into reptiles and mammals and a few subsets of each returned to the ocean as sea snakes, sea turtles, seals, manatees, and whales. Plant forms such as kelp and other algae grow in the wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flounder
Flounders are a group of flatfish species. They are demersal fish, found at the bottom of oceans around the world; some species will also enter estuaries. Taxonomy The name "flounder" is used for several only distantly related species, though all are in the suborder Pleuronectoidei (families Achiropsettidae, Bothidae, Pleuronectidae, Paralichthyidae, and Samaridae). Some of the better known species that are important in fisheries are: * Western Atlantic ** Gulf flounder – ''Paralichthys albigutta'' ** Southern flounder – ''Paralichthys lethostigma'' ** Summer flounder (also known as ''fluke'') – ''Paralichthys dentatus'' ** Winter flounder – ''Pseudopleuronectes americanus'' * European waters **European flounder – ''Platichthys flesus'' ** Witch flounder – ''Glyptocephalus cynoglossus'' * North Pacific ** Halibut – ''Hippoglossus stenolepis'' ** Olive flounder – ''Paralichthys olivaceus'' Eye migration Larval flounder are born with one eye on each side o ...

Platycephalus
''Platycephalus'' is a genus of mostly marine, demersal ray-finned fish belonging to the family Platycephalidae. They are found in the eastern Mediterranean, the Indian Ocean and western Pacific Ocean. Taxonomy ''Platycephalus'' was first proposed as a genus in 1795 by the German physician and naturalist Marcus Elieser Bloch with ''Callionymus indicus'', which had been described in 1748 by Carl Linnaeus from "Asia", as its type species. This genus is classified within the family Playtcephalidae, the flatheads which the 5th edition of '' Fishes of the World'' classifies within the suborder Platycephaloidei in the order Scorpaeniformes. Etymology The genus name ''Platycephalus'' means "flat head" an allusion to the wide flattened head of these fishes which leads to the English common name flathead. Species There are currently 19 recognised species in this genus: * '' Platycephalus angustus'' Steindachner, 1866 (Steindachner's flathead) * '' Platycephalus aurimaculatus'' ...
