    •  Ask them about land snails. They are weirder. (1+ / 0-)
      Recommended by:

      Each snail produces both eggs and sperm, but they do not fertilize their own eggs. They hook up with another of their species to have sex.

      Since it is much more energy intensive to raise the fertilized eggs to term in your body, the snail will attempt to fire a "love dart" into his partner. The dart releases chemicals that force the partner to take on the role of the female.
