Now listen to part of a lecture in a biology class.
I know some scientists who were observing snakes, in the wild.
And they witnessed an encounter of this sort between two rattlesnakes.
As you may know, rattlesnakes eat various kinds of small animals-small animals that live underground, in burrows, in little holes in the ground.
And what these scientists saw was, these two rattlesnakes had found the same hole,
and both wanted to eat whatever food was in that hole.
So what happened was,
the two rattlesnakes faced each other...
and then they lifted their bodies into an upright position and made themselves as tall as possible...
and then they started pushing each other, kind of wrestling with one another,
each snake trying to gain control of the other snake.
And what's interesting
is that, during all this pushing and shoving and maneuvering,
neither snake ever tried to bite the other snake,
neither snake ever tried to injure the other snake.
So then, after this went on for a while,
one of the snakes
finally gained control of the other snake,
pushed it to the ground and held it there.
At that point, the snake that was on top
could have easily bitten the other snake.
But it didn't-
instead, it just released the other snake,
just let it go.
The snake that had lost
just slithered away...
and the snake that had won went down into the hole to look for food.
