parent_taxon tetractenos
___MASK72___ are fish belonging to the family Diodontidae ( order Tetraodontiformes ), also commonly called blowfish and , sometimes , balloonfish and globefish . They are sometimes collectively called ___MASK77___ , not to be confused with the morphologically similar and closely related Tetraodontidae , which are more commonly given this name . The Tetraodontidae are a family of primarily marine and estuarine fish of the order ___MASK16___ . The family includes many familiar species , which are variously called ___MASK77___ , puffers , balloonfish , blowfish , bubblefish , globefish , swellfish , toadfish , toadies , honey toads , sugar toads , and sea squab . They are morphologically similar to the closely related porcupinefish , which have large external spines ( unlike the thinner , hidden spines of the Tetraodontidae , which are only visible when the fish has puffed up ). The scientific name refers to the four large teeth , fused into an upper and lower plate , which are used for crushing the shells of crustaceans and mollusks , their natural prey . A genus ( genera ) is a taxonomic rank used in the biological classification of living and fossil organisms in biology . In the hierarchy of biological classification , genus comes above species and below family . In binomial nomenclature , the genus name forms the first part of the binomial species name for each species within the genus . Tetractenos is a genus of Tetraodontidae . The genus can be found throughout the Indo - West Pacific and Australia ' s southern and eastern coastlines . ___MASK30___ is a genus in the ___MASK77___ family ( Tetraodontidae ). It has a wide distribution , from Africa to Southeast Asia . The genus includes both marine , brackish water , and freshwater species . " ___MASK30___ nigroviridis " has had its genome sequenced . Binomial nomenclature ( also called binominal nomenclature or binary nomenclature ) is a formal system of naming species of living things by giving each a name composed of two parts , both of which use Latin grammatical forms , although they can be based on words from other languages . Such a name is called a binomial name ( which may be shortened to just " binomial "), a binomen or a scientific name ; more informally it is also called a Latin name . The first part of the name identifies the genus to which the species belongs ; the second part identifies the species within the genus . For example , humans belong to the genus " ___MASK27___ " and within this genus to the species " ___MASK27___ sapiens ". The " formal " introduction of this system of naming species is credited to Carl Linnaeus , effectively beginning with his work " Species Plantarum " in 1753 . But Gaspard Bauhin , in as early as 1623 , had introduced in his book " Pinax theatri botanici " ( English , " Illustrated exposition of plants ") many names of genera that were later adopted by Linnaeus . The ___MASK16___ are an order of highly derived ray - finned fish , also called the Plectognathi . Sometimes these are classified as a suborder of the order Perciformes . The ___MASK16___ are represented by 10 families and at least 349 species overall ; most are marine and dwell in and around tropical coral reefs , but a few species are found in freshwater streams and estuaries . They have no close relatives , and descend from a line of coral - dwelling species that emerged around 40 million years ago . In biology , an organism is any contiguous living system , such as an ___MASK80___ , plant , fungus , archaeon , or bacterium . All known types of organisms are capable of some degree of response to stimuli , reproduction , growth and development and homeostasis . An organism consists of one or more cells ; when it has one cell it is known as a unicellular organism ; and when it has more than one it is known as a multicellular organism . Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms . Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs .
