Order - Osteoglossiformes
Osteoglossiformes is a less developed order of ray-finned fish that contains two sub-orders. All of them live in freshwater. Members of the order are famous for having toothed or bony tongues. They also have an intestine on the left of the stomach where all other fish pass on the right. They have well-developed teeth with a shearing bite.
