In an amazing feat of natural instinct, fire ants are able to use their claws to grip diverse surfaces — including each other.
As a result of their mutual adhesion and large numbers, ant colonies can actually flow like inanimate fluids.
The video below shows how ants behave similarly to the spreading of drops, the capillary rise of menisci, and gravity-driven flow down a wall. By emulating the flow of fluids, ant colonies can remain united under stressful conditions.
