 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 mouth parts, cleaning it, sterilizing it, and after a few minutes start to move up the leg to the shoulder and would bite it for many minutes at a time until the leg falls off, amputating it effectively. Wow. And this is not just once, an isolated incident. You observe this many times.
