You have to use a diving mask. The air between the mask lens and your eyes helps you to see clearly. Diving without a mask results in everything looking blurry because you're just looking directly through the water.
You can't "see" them, but they can be found by moving around the seaweed underwater, such as the seaweed around Sootopolis.
you swim out to the spot where sootpolis is and you dive under water and go around that area until you see a spot with like a cave door and you go in. then you dive up and surf the water until you reach land.
