For example, a large school of fish can cause nearby sharks, such as the lemon shark, to enter into a feeding frenzy. This can cause the sharks to go wild, biting anything that moves, including each other or anything else within biting range. Another functional explanation for feeding frenzy is competition amongst predators. This term is most often used when referring to sharks or piranhas.
The term is occasionally used to describe a plethora of something. For instance, a 2016 Bloomburg News article is entitled: "March Madness Is a Fantasy Sports Feeding Frenzy."
In economics the term can be used to describe the economics of the music industry, as large music companies acquired smaller music companies.
