The sex life – or more precisely, death – of the antechinus was already a gory affair. And it just got grislier.
The male carnivorous marsupials copulate so fiercely their bodies fall apart and their organs shut down. At the end of their annual one- to three-week mating frenzy, nearly all the females are pregnant and their sires are dead.
In August last year, naturalist Elliot Bowerman was hiking to Point Lookout in New England National Park in north-eastern NSW. He heard a rustle in the bushes and spied an antechinus – bleeding and missing an eye, signs of sex-induced decay – dragging the body of another across the leaf litter and eating it.
