Huge water world

There is a world around us the world we walk at every day. This is the world of flowers and birds and hills and roads and so on. This is the world where everything that is alive breathes with air. And there is also another world, different world and those creatures that live in this different world never breathe with air. Those are different creatures and they live in the water world. It is sea we call the water world and it is a huge world indeed. Sea is huge and it usually belongs to more than one country. Actually, it is sea that belongs to someone but its coasts. Anyway, it is more interesting to think about the fauna and flora of this world. There are thousands of fish in the sea and those are of different kinds. There are fishes that eat flora stuff of the sea and there are such kinds of fish that feed with tiny fishes. Sometimes such fishes can attack people. For example we know that it is better for us nit to face sharks because this meeting may be the last meeting in our life. But, some people say that a shark will never attack human for no reason.
