I'm interested in the method by which ants "break off" a small amount of soil and then hold it in their jaws (?).
To clarify I know ants break off soil in small quantities, so that a single ant carries very little soil; I'm interested to understand what exactly how this happens. For example does the ant literally pick the soil directly, or does it brush it loose first etc. Further to this I'd like to know how the ant holds the soil. Is it akin to the soil being atop a palm, or more like being held between two hands?
Broader context: I'm looking into making a model of this type of soil movement and I wanted a more detailed understanding.
