The mysteries of the nautilus

A nautilus is among the stars of Underwater World Singapore's "The Masters of Disguise," a new attraction that showcases intelligent marine life found in the deep seas. The oceanarium has gathered creatures that are able to change shape or color to mimic predators or match their surroundings.

For other compelling photos, animal or otherwise, check out the Photography page.

But if you want more on the nautilus, check out the National Aquarium's website. As the aquarium aptly observes on its website, "A nautilus, like an octopus, is a very curious creature."
