It does not, as once believed, occur only as a result of extreme food shortages or artificial conditions, but commonly occurs under natural conditions in a variety of species.<ref name="PolisThe" /><ref name="Laurel R.

'''Sexual cannibalism''' is a special case of cannibalism in which a female organism kills and consumes a [[Conspecificity|conspecific]] male before, during, or after [[copulation]]. Rarely, these roles are reversed.<ref name="esc">{{cite web |url=http://ib.berkeley.edu/courses/ib160/past_papers/suttle.html |title=The Evolution of Sexual Cannibalism |author=Kenwyn Blake Suttle |year=1999 |publisher=[[University of California, Berkeley]]}}</ref><ref name="isopod">{{cite journal |url=http://www.bioone.org/perlserv/?request=get-abstract&issn=0278-0372&volume=023&issue=03&page=0662 |title=Cannibalism within mating pairs of the parasitic isopod ''Ichthyoxenus fushanensis'' |author=Min-Li Tsai & Chang-Feng Dai |journal=[[Journal of Crustacean Biology]] |volume=23 |issue=3 |year=2003 |pages=662–668 |doi=10.1651/C-2343 |format=abstract page}}</ref> Sexual cannibalism has been recorded in the female [[redback spider]], [[latrodectus|black widow spider]], [[Mantodea|praying mantis]], and [[scorpion]], among others.▼
