Anchovy Fish Diet and Foraging Behavior nAnchovies have a diverse diet primarily consisting of plankton, such as copepods, amphipods, and krill. They swim with their mouths open, filtering these tiny organisms through their gills. As water passes through their mouth and over their gills, food particles are trapped by their gill rakers and then transported to their esophagus. This method allows them to efficiently consume a variety of planktonic prey. n Physical Characteristics nCharacterized by a prominent mouth and an extended snout, anchovies also feature a single dorsal fin located near the midpoint of their body. They generally range from 3 to 6 inches (8 to 15 cm) in length, though some species may grow larger. One of their survival tactics includes forming large schools, making it difficult for predators to target a single fish. This collective swimming behavior also significantly depletes oxygen levels in the densely populated area. n The Northern Anchovy nA notable species a...
