Smooth Flutemouth
Nature has all her fun underwater. Experimenting with some of the bizarrest creatures on the planet.
It may seem odd to make a long flute shaped fish as there aren't any straight lines underwater. You'd think it would stand out like a sore thumb. But bizarrely, whether they hang horizontally or vertically in the water, these fish just seem to disappear against the background.
Admittedly, nature played it safe by giving them the ability to change colour in an instant to match their surroundings, but half the time they're not very good at that and they still manage to disappear. How clever is Nature.
