I have been diving regularly in the San Diego area since 2000, averaging about 100 dives per year, mainly in the area of La Jolla Shores, La Jolla Cove, Wreck Alley and Pt Loma, as well as being actively involved in the San Diego diving community and I do not recall hearing of any diver reports of encounters with Sevengill sharks much before 2007, when we began hearing the first reports.
The first videos, to my knowledge, taken of Sevengills locally, by Stephen Murvine an experienced local diver, begin surfacing
One of the earliest accounts [Nov. 17, 2008], involved a diver, Steve Mair, who had jumped in the water from a charter boat to retrieve a dropped buoyancy compensator, reported being ‘bumped‘ by a Sevengill.
These reports were unusual enough at the time to make the rounds on many of the local dive lists. No one had ever really heard much about ’7 Gill’ sharks and in fact, the earliest encounters, we have reason to believe that divers were misidentifying them as ’6 Gills’ due to the similarities in appearance.
We continued to hear anecdotal reports involving divers seeing or having close encounters with these animals off and on through 2008, but many of these reports were not written up or submitted to any dive lists.
It was not until early 2009 that encounters between divers and Sevengills became frequent enough to start getting documented on video and this is when we start seeing these encounters being documented.
In March of 2009, my dive buddy, Barbara Lloyd, was diving off of Broomtail Reef with a photographer friend of ours, when a large female passed between them. Actually, it made two passes, one from the right and one from the left, giving my dive buddy a excellent chance to document it on High Definition Video and our friend to capture it with a high quality wide angle SLR lens [posted here, under Video and Photos, respectively--see Dive Video ID #8]
Then, in June of 2009, two other underwater videographer acquaintances of ours, Michael Sanderson and Gary Hawkins, had encounters with a large female at La Jolla Cove and they were able to document theirs on video as well [posted under Video].
I had almost given up ever getting to see one of the magnificent creatures myself, when, while diving off of Wind ‘n’ Sea, Pt La Jolla, by boat, one late afternoon in August of 2009 with a friend, a large Sevengill passed right between us while we were only 2 meters apart.
Unfortunately, we were not quite as well prepared as our other photographer friends and, while my buddy did have a camera and attempted to take photos of the shark, we were both so startled by its sudden appearance that the photographs came out poor quality, with quite a bit of backscatter and so, are not good enough for identification purposes, although some identifying features are visible.
Although we are not positive, we think this same shark then went on to make an appearance to another dive buddy team from the same boat, about 10 minutes later. They were about 200 yards away, so unless there were two separate sharks in the same area, that’s the likely explanation for their sighting.
I submitted the story of this encounter to California Diving News and it was run in the Oct. 2009 issue, under Marine Life Encounters, below:

On Aug. 15, 2009, while diving off Pt La Jolla, my dive buddy Dave Hershman and I had a sudden and remarkable encounter with a large Sevengill Shark:
One of the first things we noticed upon reaching the bottom was absolutely no fish–anywhere. The lighting was also strange: a strange, yellowish-green tinge to everything, lending a deserted, eerie feel to the whole place.
We continued deeper and deeper into this spooky, yellowish-green ‘ghost forest’ with its odd, dearth of fish — failing to make an obvious connection in our minds: where had they all gone and why? Last week, this same area was overflowing with fish. Sometimes the fish sense something you don’t.

Another encounter involved the Program Director for Reef Check California, Colleen Wisniewski,who was doing a transect line survey off of Broomtail Reef, Ocean Beach on Friday, May 28, Ms. Wisniewski, was doing a science dive near La Jolla Cove, when she saw what she believed to be a 10 foot-long Sevengill shark.
