Oophagy

[1] Oophagy is thought to occur in all sharks in the order Lamniformes and has been recorded in the bigeye thresher (Alopias superciliosus), the pelagic thresher (A. pelagicus), the shortfin mako (Isurus oxyrinchus) and the porbeagle (Lamna nasus) among others.

[1] It also occurs in the tawny nurse shark (Nebrius ferrugineus), and in the family Pseudotriakidae.

Oophagy is used to describe the destruction of non-queen eggs in nests of eusocial insects, especially the social wasps, bees, and ants.

[5] The social wasp Polistes fuscatus use oophagy as a method to establish a dominance hierarchy; dominant females eat the eggs of subordinate females such that they no longer produce eggs, possibly due to the unnecessary expenditure of energy and resources.

Such bee species include Xylocopa sulcatipes[7] and Bombus ruderatus, where queen bees will eat larvae deposited by workers or eject them from the nest in order to maintain dominance over the colony.
