Ants used for Surgical suture
In some areas of Africa and South America, certain ants are used for surgical sutures. Dorylus gribodoi is the scientific name of one of the 60 species of ants that inhabit Africa, also known as army or legionary ants, these ants are found mainly in central and eastern Africa. Their bite is so strong and persistent that the natives use these insects as stitches, they will hold the ant by the back of its body, align its mandibles with the wound, then the ant will bite using its mandibles. Once the mandible brings both sides of the wound together, they will break off the ant's body, leaving only the head and mandibles. This creates a natural suture that can be used in the wild if no other supplies are available.
