Scientists discover cleaner ants that groom giant ants in Arizona desert

In the Arizona desert, scientists have uncovered a bizarre and almost unbelievable partnership between ants: tiny cone ants acting as cleaners for much larger harvester ants. Instead of attacking, the smaller ants crawl over the giants, licking and nibbling their bodies-even venturing between their open jaws-while the larger ants calmly allow it. The scene resembles underwater cleaning stations, where small fish groom predators like sharks.
