The World War of the Ants

Army ants are serious warriors. They prioritize unity with the colony over individual survival, which makes them a formidable force. They march in formation, killing and consuming almost everything in their path. Army ants attack other ant colonies, and they take no prisoners. Other species have developed ways to deal with army ants, otherwise they'd be long gone now. These ants don't look as awful as they act in the day-glo colors of Kurzgesagt.
