They might be really bite-y, but it turns out fire ants also have mind-blowing cohesion abilities.
Physicists have discovered that not only can a group of fire ants act as a putty-like solid, capable of being pushed down and rebounding, but they can also be poured like a liquid.
The result is some pretty amazing footage.
If scientists manage to work out how fire ants do this, it could help improve robotics and material science.
Watch this amazing New York Times video on the behaviour to be simultaneously grossed out and blown away.
