Death feigning in the face of sexual cannibalism
Original language description
Precopulatory sexual cannibalism by females affects male and female reproductive success in profoundly different ways, with the females benefiting from a meal and the male facing the risk of not reproducing at all. This sexual conflict predicts evolutionof traits to avoid cannibalism and ensure male reproductive success. We show that males of the nuptial giftgiving spider Pisaura mirabilis display a remarkable death feigning behaviour thanatosis as part of the courtship prior to mating with potentiallycannibalistic females. Thanatosis is a widespread antipredator strategy; however, it is exceptional in the context of sexual selection. When the female approached a giftdisplaying male, she usually showed interest in the gift but would sometimes attackthe male, and at this potentially dangerous moment the male could drop dead. When entering thanatosis, the male would collapse and remain completely motionless while retaining hold of the gift so it was held simultaneously by both mates.
