The article discusses research reported online April 25, 2011 in the "Proceedings of the National Academy of Sciences" by scientist Nathan Mlot and colleagues on teamwork practiced by fire ants to stay afloat together in water. Physical aspects of these practices are described, as are the rules...

They are holding onto each other to form "rafts (木筏)" on the water. An ISC statement said, “Red fire ants are more active before or after rainfall and can form large floating rafts, which move with the flow of the water to find places to stand in new areas.” It warned that ...

Fire ants form life rafts out of their own bodies to escape flooding. © Silverback Films Once on the surface, the ants band together, each locking legs with its neighbours, gradually forming a giant raft supported by the surface tension of the water. Ants are covered in fine hairs that ...

Once deposited into water in the lab, a spherical cluster of ants spread outward, like a drop of molasses. The ants grab onto one another just as they would any surface: Using claws, jaws and adhesive pads on their legs, which secrete an oily fluid that allows them to stick to relativel...

The ants’ sheer resiliency and buoyancy is also remarkable. When the researchers tried to push the floating rafts below the water’s surface, they found they could resist a significant amount of force and float back up: From video courtesy of David Hu and Nathon Mlot/Georgia Tech...
ants have developed a defense mechanism by gathering together and intertwining themselves into floating conglomerations the researchers call “rafts.” A raft is made up of worker ants that surround the queens and brood – eggs and larvae. While the brood holds bubbles, worker ants rotate...
