O ver the course of evolution, penis size has been subject to female choice and competition with male rivals. He compared hundreds of specimens of nine related species of hermit crab and showed that crustaceans that have more valuable shells have longer sexual tubes, helping them keep a grip on their homes while they extend their reproductive organs toward a mate.

When you leave your house do you ever worry about being torn from the ground by a giant bird or ruthlessly eaten alive by a vicious carnivorous snail? Do you fear your home might literally be ripped off its foundations and stolen by a particularly sly neighbor? But according to a new study published in the journal Royal Society Open Science , some hermit crabs have come up with a clever tactic to cope with this — grow a really, really long penis. These crabs can have penises that are up to 60 percent as long as their body.
