Osteoglossidae is a family of large-sized freshwater fish, which includes the arowanas and arapaima. They are commonly known as bonytongues. The family contains two extant subfamilies Arapaiminae and Osteoglossinae, with a total of five living genera.[1] 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.[2][3]
