The Discovery Channel's Shark Week is always amongst the most highly anticipated annual events on cable television. For one week out of the year, the network is pretty much all sharks all the time. This year's edition of Shark Week, which is now in its 25th year, begins on Sunday (August 12) and takes viewers to South Africa where they'll get an up close and personal look at these awesome predators as they've never seen them before.

Shark Week 2012 begins with a visit to South Africa's Seal Island where researchers go in search of a massive great white known as Colossus. Spanning 14 feet in length and dominating all other sharks in the water, Colossus is a legendary monster that required the development of a new camera to safely capture him on film. The crew reportedly took some amazing footage of this giant fish, but not before he nearly ate their expensive new toy.

To celebrate South Africa's prominent role in Shark Week 2012, the Visit South Africa Facebook page has taken on a special shark theme. Not only are there plenty of frightening images of the aquatic beasts, but the page is also hosting a "Shark Smarts" quiz that rewards one winner with a trip for two to visit South Africa for themselves. That trip includes airfare, three nights stay in Cape Town at the luxurious Table Bay Hotel and a shark cage diving experience with Marine Dynamics.

If you're a fan of Discovery's Shark Week then set your DVR's to capture all the action starting on Sunday, then head over to the Visit South Africa page to test your knowledge of the big fish. Who knows, it could just earn you a face-to-face encounter with a great white.
