Researchers studying various species of animals on Australia’s Kangaroo Island stumbled upon a colony of Polyrhachis femorata ants that they believed was dead until one of its members moved slightly.
Feigning death, also known as thanatosis or tonic immobility is a well-documented defense mechanism observed in dozens of animal species, from insects and lizards to birds and mammals. Some of these natural actors are better than others at playing dead, but what they all have in common is implying this particular defense strategy on an individual basis. However, in what many consider a world-first, a team of researchers encountered an entire colony of dozens of ants that all played dead at the same time when threatened. And they all played their part so well, contorting their bodies in unnatural positions and remaining completely still, that the team was convinced they were all dead.
