Several species of ants including fire ants, formica and red imported fire ant, have developed adaptation to survive floods that threaten the colony. While individual fire ants are hydrophobic and flounder at the waters surface, large groups of ants can link together to form a temporary living clump, known as raft, and float along the waterline for as many as 12 days until reaching dry land. These clumps can include as many as 100,000 individual ants while the queen and larvae are evacuated from the flooding colony sitting upon this living raft. Ants clumped in this way will recognize different fluid flow conditions and adapt their behavior accordingly to preserve the raft's stability.
