Incredible footage reveals how ants go to extreme lengths to help an injured nestmate.
These African Matabele ants are carrying a wounded nestmate after a battle with termites.
The rescue behaviour is triggered when the injured ant excretes a chemical substance, calling for help.
Inside the nest, 'nurse ants' intensively lick the wounds, applying antimicrobial substances with their saliva, inhibiting infections.
Without such treatment, 80% of the injured die.
See how they do it in the video above.
