Common snook are [[Predation|opportunistic predators]] whose feeding habits indicate a positive relationship between their size and the size of their prey, meaning that as the snook grows, it feeds on larger and larger prey.<ref name=Blewett>{{cite journal|last1=Blewett|first1=N.R.|last2=Hensley|first2=R.A.|last3=Stevens|first3=P.W.|title=Feeding habits of common snook, Centropomus undecimalis, in Charlotte Harbor, Florida|journal=Gulf and Caribbean Research|date=2006|volume=18|page=1|doi=10.18785/gcr.1801.01|url=http://www.usm.edu/gcrl/gulf_caribbean_research/docs/Abstracts%20from%20Vol%2018%202005.pdf|access-date=2014-07-28|archive-url=https://web.archive.org/web/20140728100506/http://www.usm.edu/gcrl/gulf_caribbean_research/docs/Abstracts%20from%20Vol%2018%202005.pdf|archive-date=2014-07-28|url-status=dead}}</ref> Common snook occasionally engage in [[Cannibalism (zoology)|cannibalism]].<ref name="Adams and Wolfe">{{cite journal|last1=Adams|first1=A.J.|last2=Wolfe|first2=R.K.|title=Cannibalism of juveniles by adult common snook (Centropomus undecimalis)|journal=Gulf of Mexico Science|date=2006|volume=24|issue=1/2|page=11|url=http://fishermanscoast.com/research/Adams%20and%20Wolfe%20GOMS%202006%20snook.pdf}}</ref> This usually occurs during the winter when adults and juveniles are in close proximity to one another within their estuarine habitats.<ref name="Adams and Wolfe" /> This form of cannibalism where the juveniles are fed on by the adults is referred to as intercohort cannibalism.<ref name="Adams and Wolfe" /> The adult common snook that cannibalize juveniles most likely target them because the juveniles may be the largest of the available prey, so are nutritionally efficient to prey upon.<ref name="Adams and Wolfe" />
