Most slugs and snails are both male and female in the same body. Even so, they usually mate with another slug or snail, and mating rituals may be very complicated. For example, one great gray slug meets another on the ground, and starts a slimy embrace. The pair climb up vegetation, entwining and producing so much slime that it forms a rope up to 39 in (I m) long. The pair dangles from the end of this as they complete their mating in mid-air.
