[quote]The vortex of ants, called the ant death spiral by some, is a circular mill where a group of ants (sometimes hundreds to millions of ants) get separated from the main swarm and ended up following each other’s scent in a circle. It’s called the death spiral because they continue to go in circles until they’re exhausted and die.
