Most spiders use a modified leg to procreate but the harvestman, also known as a Daddy Longlegs, has a special attachment for that sort of thing that is normally hidden inside the body of the spider. This ancient Daddy Longlegs is unique, he is the first to be found in such a 'passionate' stance and the shape and size of his baby maker has prompted researchers to declare a new family of arachnids based on this finding.
