strongest ants
I
f you compare the size of an average ant and the weight
he can carry to that of a human’s ability, an ant is very
strong. But some species of ants are even stronger. The
leafcutter ant can lift material that is 50 times heavier than
his own bodyweight. Asian weaver ants can lift around 100
times their own weight. It is estimated that a field ant’s neck
can support 5,000 times his own weight. The best part is that
they don’t only pick up the weight, they also carry it over long
distances. Now that’s what we call strong!Are ants really so strong?

named him Ledumahadi mafube, which is Sesotho for ‘a giant thunderclap at dawn’. It is believed that
there are many more dinosaurs waiting to be discovered. The 40m Argentinosaurus was the longest
dinosaur, while the Lesothosaurus was the smallest – about the size of a chicken.How many species of dinosaurs have been found around the world?
