This striking photograph captures a great white shark in all its predatory glory, breaching the ocean's surface in pursuit of prey. After the 1916 New Jersey shark attacks, some marine biologists hypothesized that great whites could grow to lengths of 40 feet, said shark expert Andy Dehart. Today, though, marine biologists know the longest confirmed great white shark to be a still-imposing 21 feet long. (The Discovery Channel )
