 Joining us now is Dr. Eric Frank, a behavioral ecologist from the University of Würzburg in Germany and lead author of the study. Welcome to you. So tell us more. What do the ants do? Yes, hello. Thank you for having me. So basically what we discovered is that these ants, when they get injured higher up on the leg and they lose the leg, other ants inside the nest would start licking the wound with their mouse parts, cleaning it, sterilizing it.
