Pictured: Incredible gravity-defying ant that can carry 100 times its body weight. This extraordinary image of an ant carrying 100 times its own body weight has scooped first prize in a science photography competition. The photo shows an Asian weaver ant hanging upside down on a glass-like surface and holding a 500mg weight in its jaws.
In absolute terms, the African elephant is by far the strongest living animal but it can only lift 25% of its bodyweight.
