Nature is filled with fascinating, and often brutal, mating behaviors—but few are as shocking as those of the octopus. In some species, particularly the larger Pacific striped octopus, female octopuses are known to attack, strangle, and even consume their male counterparts if they’re not receptive to mating. While this might seem extreme, it’s part of the high-stakes world of cephalopod courtship, where survival and reproduction are constantly at odds.

This phenomenon, known as sexual cannibalism, isn’t exclusive to octopuses. It’s also famously observed in praying mantises and certain spider species, where the female consumes the male either during or after mating. Scientists believe this behavior may provide the female with essential nutrients to support egg development, making it an evolutionary strategy for reproductive success—even if it comes at the male’s expense.

Interestingly, male octopuses often approach mating with caution. Some use long arms to deposit sperm at a distance, hoping to avoid the female’s wrath. Others mate only once and die soon after, a natural process known as “senescence” that affects both sexes. In the bizarre world of octopus love, it’s less about romance and more about strategy—and survival.
