How many fish are there in the ocean?

    This question is, more or less, unanswerable. Millions of millions. Fish range in size from the whale shark to tiny guppies; they live in reefs, in the deep ocean, near the surface — everywhere. The oceans are incredibly vast, and we still don’t really know very much about the types of fish that live in the deep, deep regions. We definitely don’t know enough to count them accurately. Scientists may be able to estimate populations of commercially important fish like tuna, but even that isn’t an exact science. Factor in the sheer number of species and variables across the breadth of the world’s oceans, and you simply have a staggeringly huge number with an equally staggering margin of error. It would be a meaningless number, given how much guesswork would be involved.
