Weird Question From My Year 6 Science Class

[K-Holed]

One property you find in water is the deeper you go, the more of the spectrum that is absorbed. Dependent on water depth, what looks like a brightly coloured fish in our aquarium would be almost invisible. Red is the first colour to vanish, followed by orange then yellow etc. etc. By around 200m, light will cease to penertrate in the visible spectrum.

So you think fish that live at different depths see differently? Sounds like a logical explanation to me.

I can't be sure on that one. But it does go some way to understanding why marine fish may be so brightly coloured. At depth they'd actually be very well camoflauged.

That would make sense.

Kind of like how people all see the same, because we are all exposed to the same amount of light.
