Colonies of fire ants survive floods by forming a raft using collective hydrophobicity.

Edit Hook
"Superhydrophobic surfaces do not necessarily need to be a layer of a single materials. By massing together, some ants effectively form a superhydrophobic raft." (Nature's Raincoats 2009)
Edit Summary


"'Fire ants do form these living rafts of ants, when they get flooded,' [Goodisman] explains. 'They basically float on their young and they'll cannibalize each other to some extent until they hit land. Ants die but the colony survives, that's what it is all about. The colony survives, the queen survives.'" (O'Brien & Kellan 2009)
