As South Carolina recovers from heavy rain and flooding , one insect is showing off its clever strategy for survival.
Fox Carolina’s Adrian Acosta recorded footage of a group of fire ants clinging together to form a life raft as they float on the water.
Acosta said he initially thought he was looking at a pile of mud, but closer examination revealed a swarm of ants.
The phenomenon is, in fact, a common survival tactic for fire ants faced with flood conditions.
As researchers studying the behavior in 2011 explained in National Geographic:
In less than two minutes the ants had linked "hands" to form a floating structure that kept all the insects safe. Even the ants down below can survive this way, thanks to tiny hairs on the ants' bodies that trap a thin layer of air.
A reporter from NBC affiliate WSAV spotted and recorded another cluster of ants performing the buoyant feat in Dorchester County, South Carolina.
In addition to the usual predators, the ant-rafts need to keep an eye out for soap , Live Science explains. That's because they rely on the surface tension of water to float, and soap will lower that surface tension, causing the ants to fall in.
