Why are sharks dark on the top but light on the bottom?.
In: Biology
If you’re at the bottom of the sea looking up, what you see is lighter water, cos sunlight is reaching it. If you’re at the top of the sea looking down, what you see is darker water, cos sunlight doesn’t penetrate that far. If you’re looking up, you see the bottom of a shark. If you’re looking down, you see the top of it.
