Shark tagged and released
Great White Shark observed off our observation vessel as part of annual Sharktober naturalist tours lead by David McGuire, Sea Stewards. Each year we conduct whale and wildlife watching tours to the Farallon Islands to watch for sharks and discuss the entire ecosystem.

From the Shark Research Committee:
On July 20, 2011, Myung Kil was surfing at Ocean Beach, San Francisco, almost opposite Beach Chalet. It was about 8:30 AM and he had been on the water 45 minutes. The sky was clear with air and water temperatures estimated in the low 60s and 50s Fahrenheit, respectively. The ocean was calm with decent swells for good small to midsized surf. No marine mammals were observed in the area. Kil reported: “I was waiting on my board for a set, looking outbound when slightly to my left, perhaps 10 o’clock and about 25 yards away, I saw a fairly large triangle fin a good foot to foot and a half and part of the sharks brownish back exposed from the trough of an incoming swell. It was moving perpendicular to me, cruised under the incoming swell and disappeared. I don’t recall much water thrashing when the shark broke the surface. I’d seen birds dive into the ocean for baitfish previously. I waited for seconds, registering that I had seen a shark, looked at the other surfers around me then saw a decent wave to catch back to shore perhaps minutes later. The shark had a very large dorsal fin, light and water shimmered on the back end of the shark, which was visible slightly out of the swell for a moment. In the light, and water, the shark looked brownish and I would guess 8 feet in length from my perspective.”
