Last week, we showed you an image of a gaping shark's jaw and asked if you thought it was real or not.

While a few people believed the image was distorted -- some sort of camera trick -- many believed the jaws in the photo are those of a megalodon, an ancient ancestor to today's great white that could grow 60 to 70 feet in length. This belief informed many votes, and just over half of the 1230+ voters thought the image was real.

This image was taken in 1995, at a natural history auction. According to CNN, "The [auction's] top estimate of $1.2 million is for a 10-foot-tall reconstructed jaw of an ancient shark believed to have been 70 feet long. The gums are fiberglass, but the 184 teeth are real. The longest is 7 and five-eighths inches." So the image is real; however, portions of the model are manmade -- although they're based on carefully-calculated proportions. Consequently, in my mind, if you voted real, you're right. (But if you voted not real, we'll let it slide this week, because it was kind of a trick question.)
