The article discusses the mechanics involved in the suction feeding in fishes. According to the author, most fishes use suction to obtain all of their food. A fluid dynamic modeling and flow data from bluegill sunfish was used by two researchers to prove that the dominant force carrying the prey to the predator fish's mouth is the pressure gradient generated by the rapid opening of the mouth.
