Do ants have brains?
Ants have a main brain and several smaller brains that run along
the length of their bodies called, "ganglia". The ganglia are
little assistant brains to the main brain. The brain inside the
ants head controls things like smell, sight and touch, but the
smaller brains control, to some degree movement of the ant. Have
you ever noticed that an ant will continue to twitch if you step on
it? Even if the head is separated from the ants body, the legs will
still twitch. This is because the smaller brains (ganglia) are
still telling the ants legs to move!
