Red ants

A mound of twigs abounds with life at the edge of the footpath. An anthill in full action. On average it will house 300 000 red ants. This sociable insect is the epitome of perfection. It has strong jaws for digging, cutting and transporting; antennae for communicating and orientating; three pairs of non-slip feet for getting about; compound eyes to see as with a kaleidoscope; a chitin armour and a reserve of formic acid with which to attack. A simple experiment: put your hand close to the anthill, without touching it. Let the ants react then put your tongue to your hand...formic acid!
