This undated handout picture made available by Professor Maydianne Andrade of the University of Toronto on September 20, 2016, shows an adult female Australian redback spider (Latrodectus hasselti) with dead a male near her mouthparts. Widow spider males, known for their tendency to end up as a post-coital snack, have developed a rather gruesome method of saving their own skins, scientists revealed on September 21, 2016. To avoid becoming the lunch of adult females, some males have taken to inseminating juveniles which have no external genitalia yet – penetrating right through their exoskeletons to deposit sperm.
