How do fish get into literally every body of water, no matter how remote or isolated?

Question

I’ve never gotten the full explication on this. I hear animals bring the eggs, esp birds but that doesn’t really make sense to me. Don’t the eggs need to be fertilized in the water?

Answer 1

In some species of fish (mostly ones that live in areas with seasonal lakes) the eggs can actually survive being dried out. So the fish lay the eggs, the water dries up and the eggs dry out. When the eggs get wet again, they hatch.
