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 a intestine on the left of the stomach where all other fish pass on the right. They have well developed teeth with a sheering bite.
