Some female octopuses aren’t afraid to repel an unwanted advance by flinging a pile of junk.

In one clip, a female octopus can be seen tossing off a shell after chowing down its contents.

A throw by a female octopus that hits a male attempting to mate with her.

Octopuses can sometimes change their coloration, with darker skin colors associated with aggression.

Still, only about 17% of the throws observed actually hit other individual octopuses.

All the more reason to avoid these suckers – and their actual suckers.
