The way the squid mate is something else. Little is known about the details but it seems that the male ejaculates a packet of sperm at the mating partner, and the packet turns inside out, essentially shooting the sperm contained in a membrane into the flesh of the partner, where they stay embedded until the female (if the shooter has been lucky) is ready to fertilize its eggs. If males are the recipient of these rocket sperm, they are just stuck with them. It is the kind of mating that would make a good video game.
