Can fish see what is below them?

Here's why:

* Eye placement: Most fish have eyes on the sides of their head, giving them excellent binocular vision to see what's in front of them. However, they have limited ability to see directly below them.

* Light and water: Light doesn't travel as far underwater as it does in air, and it gets scattered. This makes it hard for fish to see clearly in murky water or at great depths.

* Fish species: Some fish, like flatfish, have eyes on top of their heads allowing them to see up and down, but not directly below them. Others, like some deep-sea fish, have upward-facing eyes for spotting prey in the dim light above.

So, while a fish might be able to see a shadow or movement below them, they probably don't have a clear view of what's directly beneath them.
