Amazing how much diversity there is in such as small area - thousands and thousands of years to some fish to have certain shaped mouths and heads to allow them to eat small amounts of food that have been captured by coral, urchins, etc. and how those animals, which many might think are plants, to have developed the ability to be anchored on the sea floor and still get enough food to survive. Or the different types of camouflage to avoid being seen by larger predator fish. It's doubtful that anyone would have thought to create a fish that's bright orange and blue with a yellow tail and think, "This would be a great way for this fish to be inconspicuous! ", but, it's taken millennia for that fish to look like this - and, in millennia, as long as we don't destroy life on this planet, the descendents of that fish will probably look as different to this fish as this one would look to its ancestors several thousands of years in the past.
