Whenever I did something wrong as a little girl, I thought I had a surefire way of escaping my parents.
I would hide behind a large potted plant we had and close my eyes.
Somehow, I thought that my parents wouldn’t be able to see me if I did this. Unfortunately for me, their eyesight was a bit better than I’d bargained on.
If you look at the natural world, you’ll find that I’m not the only one who often thinks they can’t be seen.
Take the blue tang fish, made famous by its cartoon equivalent in the Pixar movies “Finding Nemo” and “Finding Dory.”
Like a few other reef fish, this aquatic animal is blue and yellow. To other fish and to its predators, the blue tang is perfectly camouflaged. To them, its yellow markings seem to disappear against similarly coloured corals, and its blue body blends in with the shade of the water.
There’s only one problem:
To snorkelling humans, the blue tang sticks out like a sore thumb. Far from being camouflaged, this fish’s dramatic colours are incredibly conspicuous to our eyes. Why is that?
It’s because our eyesight is very different from that of undersea creatures. The particular trio of cones in human vision is especially good at discriminating blues and yellows.
So what is hidden to other fish is glaringly obvious to us.
I think God’s “eyesight” works in a similar fashion.Read more
