Bonytongue refers to a group of freshwater fish belonging to the family Osteoglossidae. These fish are characterized by their bony tongues, which have a unique structure that helps them grasp and consume prey. Bonytongues are primarily found in tropical regions, particularly in rivers and lakes of Africa, Asia, and South America. One of the most well-known species is the Arowana, often sought after in the aquarium trade for its striking appearance. Bonytongues are carnivorous and typically feed on insects, small fish, and crustaceans. Their distinctive features and behaviors make them a fascinating subject for both researchers and fish enthusiasts.
