Feeding frenzy

In ecology, a feeding frenzy is a situation where oversaturation of a supply of food leads to rapid feeding by predatory animals. For example, a large school of fish can cause nearby sharks to enter a feeding frenzy. This can cause the sharks to go wild, biting anything that moves, including each other or anything else within biting range. This term is most often used when referring to sharks or piranhas, due to these being some of the most feared predators.
