Ants have strong, jointed legs that allow them to carry heavy loads, and their exoskeleton, or outer shell, provides extra support. They also have powerful mandibles, or jaws, that can grasp onto objects and hold them firmly in place. Because of these traits, entomologists estimate that ants can lift anywhere from 50-100 times their body weight.
One study published in the Journal of Experimental Biology found that the Asian weaver ant Oecophylla smaragdina can lift objects up to 100 times their own body weight using their jaws. Similarly, the leafcutter ant Atta cephalotes can carry up to 50 times their own body weight, according to a study published in the journal Insectes Sociaux.
