Common snookThe common snook (Centropomus undecimalis) is a species of marinefish in the familyCentropomidae of the orderCarangiformes. The common snook is also known as the sergeant fish or robalo. It was originally assigned to the sciaenid genus Sciaena;Sciaena undecimradiatus and Centropomus undecimradiatus are obsolete synonyms for the species. One of the largest snooks, C. undecimalis grows to a maximum overall length of 140 cm (4.6 ft). The common length is 50 cm (1.6 ft).
Pacific OceanLargest ocean on EarthThe Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It stretches from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east.
Atlantic OceanOceanic divisionThis video was taken by the crew of on board the ISS. The pass starts from just northeast of the island of Newfoundland over the North Atlantic Ocean to central Africa, over South Sudan.The Atlantic Ocean is the second largest of the world's five oceans, with an area of about 85,133,000 square kilometers (32,870,000 sq mi). It covers approximately 17% of Earth's surface and about 24% of its water surface area.Game fish
Family (taxonomy)Family (Latin: familia, pl.: familiae) is one of the eight major hierarchicaltaxonomic 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.
Type speciesA type species (species typica) is the species considered to be permanently taxonomically associated with the name of a genus or subgenus, and that is used to identify it and distinguish it from others. In modern times, it is normally assigned when the genus or subgenus is first named. Any taxonomic revisions must be done in such a way that the genus or subgenus retains the type species if the genus is to keep its name.LatidaeGenusGenus (; pl.: genera) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as 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.
CladisticsCladistics ( ; from Ancient Greekkládos 'branch') is an approach to biological classification in which organisms are categorized in groups ("clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics (synapomorphies) that are not present in more distant groups and ancestors.
ParaphylyParaphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic with respect to the excluded subgroups. In contrast, a monophyletic grouping (a clade) includes a common ancestor and all of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics.
PercoideiPercoidei is a suborder of bony fishes in the order Perciformes. Many commercially harvested fish species are considered to be contained in this suborder, including the groupers, seabasses and perches.
