In 2009, a beluga whale saved a drowning diver by carrying her to the surface.

Lady Beetle (Harmonia sp., Coccinellidae)

Although cannibalism of eggs by Coccinellid larva (in fact amongst and between all hungry Coccinellid life stages) is well-recognized and researched (this occurs typically when prey sources are limited in quality and quantity, or as an intentional means of boosting survival probability for first hatchings where egg clustering occurs), less is known about egg cannibalism and predation by adult Coccinellidae. What is apparent (maybe because they are an easier genus to study and very common), is that the Harmonia genus seems to be very adept at cannibalism at all stages of life both intra-specifically and inter-specifically. Cannibalism of other Coccinellid species is significant where Harmonia occur as an invasive species (i.e. everywhere outside of Asia) and where they are overwhelming native species.

Certainly, nutritional stress and interspecies competition are logical reasons for egg cannibalism by adult beetles, but it is also proposed that females lay fertile and trophic (infertile) eggs. The purpose of the unviable trophic eggs is purely for the nutritional benefit of the female and not a failure of the reproductive process, and not a phenomenon restricted to lady beetles. So, in fact, the consumption of Coccinellid eggs by adult beetles is not an act of cannibalism in these circumstances, but an intentional  behavior aimed at supplementing nutrition.
