3. Leafcutter Ant
The 2.1 cm long leaf cutter ants are one of the most incredibly strong creatures in the world. This small ant can carry the objects that are 50 times more heavier than their own body weight. The leafcutter ants can also cover remarkable distances while carrying the weight. They have remarkably powerful jaws to carry large pieces of leaves to their nests.
Even though leafcutter ants are very small in size, they have great cross sectional area of muscles than larger animals. Leafcutter ants can also vibrate their jaws at a rate of 1000 times per second. So they can produce an immense force to move large objects.
Leafcutter ants also called as ‘parasol ants’ because of the unique way they carry the leaf pieces. Leafcutter ants don’t feed on leaves. Instead, they use the leaf pieces as fertilize to cultivate fungi. Generally a colony of leafcutter ants includes millions of individuals. They also can be a severe threat to agricultural ecosystem. Because a colony of leafcutter ants can defoliate many valuable crops and plants.
