Why These Ants Amputate Legs (It's Biochemistry)

Florida Carpenter Ants (Camponotus floridanus) are the only non-human animals known to perform life-saving amputations. In this video, we dive into the biochemistry of infection and how these "Ant Surgeons" use mechanical cleaning and triage to survive pathogens without specialized antimicrobial glands.

We’ll explore the role of hemolymph circulation in femur vs. tibia injuries and why timing is everything in the world of insect "medicine."
