Bony Tongues and Relatives: Osteoglossiformes

Bony Tongues And Their Relatives And People

Most bony tongues and their relatives, particularly the larger species, are important food fishes. Bony tongues are used in public and home aquariums.


There are many species of bony tongues. Only one of them, the mooneye, lives in North America. The arapaima, which lives in the Amazon region of South America, is one of the largest freshwater fishes, weighing as much as 441 pounds (200 kilograms) and reaching a length of 15 feet (4.5 meters). The elephantfish is weakly electric. Other bony tongues are the arowana, the clown knifefish, and the elephantnose fish.
