Male centipedes not only have to find a receptive female for mating but to also lift her and ensure that their feet are joined — and you know how many feet centipedes have! To do this, the male has sticky feet to help with the lifting and entangling, along with two specially adapted ‘feet’ that lift and clasp the female. Once clasped and entangled together, it can take hours for the male to transfer his sperm. Sounds fun? Well, the catch is that sometimes the couple may not be tightly enough bound to each other and another male can come along and try to 'unzip' their joined feet. If he proves to be the more dominant male by successfully unzipping the couple, he then gets to mate with the female. Casts a whole new light on the phrase ‘zip me up, darling’!
