Conspicuous Camouflage

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.

How Are You Sleeping?

How have you been sleeping recently? Do you find yourself waking at night, worried about the future?

Wish you could sleep as soundly as your pet?

Cats and dogs have an advantage when it comes to sleeping deeply. They’re predator animals: in the wild, canines and felines are hunters. Large predator mammals generally spend more time in deep non-REM sleep than their prey.

Prey animals such as rabbits or deer, the hunted, spend more time in lighter non-REM sleep. They also experience very little REM sleep at all. Their survival is dependent on being permanently alert, and the paralysis of REM sleep would make them too vulnerable to their predators.

I wonder if the poor sleep we humans often experience relates to our feeling “hunted,” relentlessly chased by worries, deadlines, and obligations?

Is there a way we can calm our anxious minds and get a good night’s rest?

Yes! I believe the Bible offers some tips to help us sleep better.
