Check out this remarkable video taken by Chuck Patterson off of San Onofre State Beach, from a paddleboard.
This is from Chuck’s Vimeo site:
the day before I shot this video, I was SUP surfing with a couple friends and 2 sharks circled us for about 15 minutes. the next day, I decided to go back out at around the same time and take my GO PRO HD HERO camera (gopro.com) mounted on a 10 ft pole and do some exploring.
Sure enough within 5 minutes a 9 ft shark came out of no where and circled twice and slapped his tail on my board before disappearing. then a minute later a 7 ft young juvenile Great White swam circles around me for 12 minutes. It was an unreal experience that I will cherish forever
Sean van Sommeran of the Pelagic Shark Research Foundation has pointed out that, if you look closely at the left side of the shark around minute 1:20, you can see a research tag implanted under the dorsal fin.
