In the case of eggs, this means that r-strategists lay large numbers of eggs, while K-strategists take care to protect a smaller number of eggs. Lacebugs of the genus Corythucha are subject to egg predation by obligate egg predators like mirid bugs , pirate bugs , and thrips , and respond to it in varying ways.
Stickleback fish have been documented performing distraction displays. A nesting male three-spined stickleback, when approached by a group of conspecifics, will perform a distraction display by digging or pointing into the substrate away from the nest in order to protect his eggs from cannibalism.

The male red colobus monkeys group together and place themselves between predators and the group's females and juveniles. The males jump together and actively bite the chimpanzees. [52]

A sea turtle clutch. A clutch of eggs is the group of eggs produced by birds, amphibians, or reptiles, often at a single time, particularly those laid in a nest. In birds, destruction of a clutch by predators (or removal by humans, for example the California condor breeding program) results in double-clutching. The technique is used to double ...
Although sea turtles usually lay around one hundred eggs at a time, on average only one of the eggs from the nest will survive to adulthood. [2] While many of the things that endanger these hatchlings are natural, such as predators including sharks, raccoons, foxes, and seagulls, [ 3 ] many new threats to the sea turtle species are anthropogenic.
Many turtles from the same beaches show up at the same feeding areas. Once reaching sexual maturity in the Atlantic Oceans, the female Loggerhead makes the long trip back to her natal beach to lay her eggs. The Loggerhead sea turtle in the North Atlantic cover more than 9,000 miles round trip to lay eggs on the North American shore.
