It's impossible to give an exact number of sharks in the world because:
* They live in vast, deep oceans: We haven't explored every corner of the ocean.
* Population fluctuates: Shark populations change due to things like fishing, pollution, and climate change.
* Difficult to count: Tracking sharks is difficult, and there isn't a global census.
However, estimates suggest there are millions of sharks in the world!
