To survive S. Carolina floods, ants build rafts from their own bodies
The mammoth floods in South Carolina have 聽and left at least nine dams breached. But the water doesn鈥檛 seem to be much of a problem for ants, who are building body rafts to stay afloat.
While reporting on the flood conditions, FOX Carolina reporter Adrian Acosta noticed that what he thought was a pile of mud, was actually moving. Upon closer inspection he realized the mass wasn鈥檛 dirt, but an .
Ants collective behavior is put to good use during floods, as the tiny creatures 鈥渓ink legs and mouths together, weaving a raft in a process that can take ,鈥� says National Geographic.
This behavior is consistent with research done by scientists at Georgia Tech and the University of Lausanne, Switzerland.
According to scientists at Georgia Tech, the ants weave so tightly that water cannot penetrate, allowing the ants to at a time.
鈥淭he worker ants and brood were ,鈥� say University of Lausanne researchers . Upon further experimentation, they found that "larvae and pupae (with and without cocoons) were significantly more buoyant than workers."
The brood, or ant babies, 鈥渟erve as a better flotation device鈥� due to their higher buoyancy and therefore form the bottom of the raft, reported the 海角大神 Science Monitor.
Ultimately, the ants rafting mechanism is a survival tactic meant to protect the queen.
"The workers protected the most vulnerable and valuable nest mate, the queen, by placing her in the center of the raft, and the worker ants used the buoyancy of the brood at the base and recovery ability of workers to and minimize ant injury or death."
But this isn鈥檛 the first time ants have stayed afloat during floods. also reported seeing ant islands in their flooded yards following torrential rains in May, USA Today reported.
