Osteoglossidae
Sign in to saveOsteoglossidae is a family of large-sized freshwater fish, which includes the arowanas. They are commonly known as bonytongues.

Gli Arapaimidae sono una famiglia di pesci d'acqua dolce osteoglossiformi, noti anche come pesci dalle lingue ossee. Questa famiglia comprende gli arapaima dei bacini dell'Amazzonia e di Essequibo, in Sud America, e gli arowana africani dall'Africa.[1] Questa famiglia è a volte considerata parte della famiglia degli arowana, Osteoglossidae. Uno studio genetico mostra che gli Arapaimidae (arapaima e arowana africani) si sono discostati dagli Osteoglossidae circa 220 milioni di anni fa, durante il Triassico superiore. All'interno di Osteoglossidae, la stirpe che porta al sudamericano arowana Osteoglossum sudamericani si è discostato circa 170 milioni di anni fa, durante il Giurassico medio. Gli arowana asiatici e australiani del genere Scleropages si separarono circa 140 milioni di anni fa, durante il Cretaceo inferiore.[2][3] Indice 1 Distribuzione e habitat 2 Tassonomia 3 Note 4 Altri progetti 5 Collegamenti esterni Distribuzione e habitat Le specie del genere Arapaima sono originarie del Sud America mentre Heterotis niloticus è diffuso in Africa.

Osteoglossidae is a family of large-sized freshwater fish, which includes the arowanas. They are commonly known as bonytongues. The family has been regarded as containing two extant subfamilies Arapaiminae and Osteoglossinae, with a total of five living genera, but these are regarded as valid families in ''Eschmeyer's Catalog of Fishes The extinct Phareodontinae are known from worldwide during the Late Cretaceous and Paleogene; they are generally considered to be crown group osteoglossids that are more closely related to one of the extant osteoglossid subfamilies than the other, though their exact position varies.
== Evolution == Osteoglossids are basal teleosts that originated during the Cretaceous, and are placed in the actinopterygian order Osteoglossiformes. The traditionally defined wider family includes several extant species from South America, one from Africa, two from Asia, and two from Australia. The earliest known osteoglossid is Cretophareodus from the middle Campanian of the Dinosaur Park Formation, Canada, but a potentially older genus may be Chanopsis from the Albian of the Democratic Republic of the Congo.
