Divester.com offers a series of images of sharks and challenges their readers to guess whether they're real or fake. About half of the images have been posted here before, but that still leaves half that should be new. Here are a few of the ones I hadn't seen before.
They are, from left to right: fake, fake, and probably fake real. The diver attacked by a shark is from a Weekly World News cover. The girl swimming with sharks is an image created by Australian photographer Mike Berceanu (it's a composite of a number of different images), and the one of the shark approaching a kayaker just looks too good to be true (though there's no firm evidence that it is fake), but it's real. It appeared in the September 2005 edition of Africa Geographic.
