National Geographic travels to Shark Island with Nigel Marvin for a beautiful shark series in August.

I told you RIGHT HERE earlier in the week about Shark Month returning to Animal Planet (DStv 264) in August but sharks are also popping up in August in a stunning shark series on National Geographic (DStv 260) as well.

Its been on before but National Geographic has programmed Shark Island with Nigel Marvin, a simply stunning series that will debut on Monday, August 23 on the channel at 21:00 and run for that whole week in the same hour long timeslot.

Wildlife expert Nigel Marven travels to the Pacific island of Cocos, an atoll near the coast of Costa Rica. With a dive boat, a specialist crew and selection of equipment, including a state-of-the-art miniature submarine which can go 400 metres down for up to four hours, he has four weeks to discover why there is such a great concentration of sharks in the area - and the results and visual underwater footage will take your breath away.
