A violent but evolutionarily effective mating strategy has been spotted in spiders from Israel.
Males of the aptly-named Harpactea sadistica species pierce the abdomen of females, fertilising their eggs directly in the ovaries.
The so-called traumatic insemination gives the first male to inseminate a reproductive advantage by bypassing structures in the females' genitalia.
