Watching the chambered nautilus will remind you that it's a rare and beautiful creature and is considered a living relic of the past.
The nautilus is related to the first cephalopods that appeared on earth some 500 million years ago.
Nautiluses are almost exclusively found in the Indo-Pacific Ocean, inhabiting the deep slopes of coral reefs and existing in depths of several hundred meters or more.
These animals can be quite rare and to see one in such very clear footage like this is a real treat.
Though the nautilus in this video didn't appear to be all that deep, it makes the footage taken that much more stunning.
Incredibly, at this time, it does not have any national or international regulations protecting them. Because of their unique ecological range and the late onset of their sexual maturity, biologists are now investigating the need to protect them from overharvesting to the point of extinction.
The nautilus is captured for its prized shell, not only because of its shape, but for the inner layer which is used as a pearl substitute.
