Editing Atlantic mackerel (section)

===Feeding===
When feeding on larger prey, schools tend to break down into shoals and individuals find food on their own. When consuming plankton, however, Atlantic mackerel form tight aggregations, open their mouths as wide as possible, and extend their [[operculum (fish)|operculums]], swimming in a tightly packed school that acts like a series of miniature tow nets. Spaced only about the diameter of a single fish's mouth apart, this formation greatly reduces the ability of plankton to evade capture, as a plankton darting out of the way of one fish is likely to end up in the jaws of another. [[Copepod]]s make up the majority of the Atlantic mackerel's diet, ''[[Calanus finmarchicus]]'' being the most abundant.<ref name=sette2/>
