As I move around, I see the little ones scurrying about. One look at me, and they start running helter skelter. And they should.
This is my territory. Every rock, every plant, is owned by me. If they choose to make their way here, they choose to give up their freedom and submit to my sovereignty. I am the king. Wait, I see a shadow looming over me. It is humongous, covering my entire territory. I guess it is time for me to exit these waters and head elsewhere.
After all, there is always a bigger fish out there.
