The mating habits of deep-sea squid have been revealed for the first time, after the discovery of a male squid with a huge elongated and erect penis. The male squid's sexual organ is almost as long as its whole body, including the squid's mantle, head and arms. That shows how male deep-sea squid inseminate females; they use their huge penis to shoot out packages of sperm, injecting them into the female's body. The discovery may also help explain how giant squid mate in the ocean depths.....
