Triacanthus biaculeatus was first formally described as Balistes biaculeatus in 1786 by the German physician and naturalist Marcus Elieser Bloch with its type locality given as the Indian Ocean. [2] In 1817 Lorenz Oken classified B. aculeatus in the new monospecific genus Triacanthus, so this species is the type species of the genus Triacanthus ...
Osteichthyes (/ ˌ ɒ s t iː ˈ ɪ k θ iː z / ost-ee-IK-theez), [2] also known as osteichthyans or commonly referred to as the bony fish, is a diverse superclass of vertebrate animals that have endoskeletons primarily composed of bone tissue.
Male seahorses have a specialized ventral brood pouch to carry the embryos, male sea dragons attach the eggs to their tails, and male pipefish may do either, depending on their species. [4] The most fundamental difference between the different lineages of the family Syngnathidae is the location of male brood pouch. [ 5 ]
Marine biology studies species that live in marine habitats. Most of the Earth's surface is covered by ocean, which is the home to marine life. Oceans average nearly four kilometers in-depth and are fringed with coastlines that run for about 360,000 kilometres. [4] [5] Marine biology can be contrasted with biological oceanography.
The Pelagibacterales are an order in the Alphaproteobacteria composed of free-living marine bacteria that make up roughly one in three cells at the ocean's surface. [ 2 ] [ 3 ] [ 4 ] Overall, members of the Pelagibacterales are estimated to make up between a quarter and a half of all prokaryotic cells in the ocean.
The classification of species within Nautilus has been contentious for decades, and the genus has been reconfigured and redefined several times throughout its history. Nautilus is the type genus of the family Nautilidae , originally defined as any coiled- shell species with simple sutures , or walls, between shell compartments. [ 7 ]
Artist representation of A. scriptus. Aluterus scriptus is a medium size fish which can grow up to 110 cm (3.6 ft) in length. [3] The body shape looks like an elongated oval, strongly compressed.
The basic ranks are species and genus. When an organism is given a species name it is assigned to a genus, and the genus name is part of the species name. The species name is also called a binomial, that is, a two-term name. For example, the zoological name for the human species is Homo sapiens. This is usually italicized in print or underlined ...
