Love the soundtrack.

That's half again as long as Bob's estimate on the size of the enormous one we ran into in Cove 2. That would be a daunting creature to encounter on scuba!

That's freaking amazing! Thanks for posting it.

wow, what a monster! any idea how deep that was?

I think it was Rob up at Hornby Island who told me the biggest one they'd seen up there was over 20 feet long ...

I've not seen the video, but I've heard several times on the board that dogfish do not react well to laser pointers. Perhaps this shark was irritated by the lasers on the sub?

According to the video it was at 3,300 feet ...

... no wonder they were in a submersible ...

Damn, that's a big fish. I guess the "huge" 13 footer's we have around here are just teenagers!

20' long?! Are white sharks up to around 20' long? ...and just think of the tini-tiny little brain that is powering that scary fish.

Here it is incase the link goes away...

Gracias Sounder.

I believe depth is that "D1001.2" label in the bottom-right. Since everything in science is done in Standard International (except certain NASA endeavors we won't go into ](*,) ) that comes out to 1001.2 meter = 3284.78 feet.

What I wouldn't give to be on a manned sub.

Hmmmmm, That's DEEP!

And that is exactly why I don't dive with a lazer pointer anymore!

I guess this is for the Marine Biologists out there, Rachel, Kevin? Is there any science behind this Shark/Laser Pointer theory? It certainly seems like lasers have an effect on sharky behavior. Has it been studied?

They're just jealous of the sub's laser beams.

All I can say is that from personal experience lasers effect my behavior. I was tagged in the right eye by a consumer-grade laser pointer a few years ago (by a teenage prankster). By law, these output a wavelength which cause permanent damage over a span of time greater than the typical reaction time of the human eye flinch/blink. In other words you should have time to get away before it causes damage. All I can say is I'd hate to experience permanent damage because the 'temporary damage' I experienced was 3 hours of HELL. I was blind in that eye and suffered the worst headache of my life. When I was hit my entire vision was completely obliterated. High intensity RED was all I saw (and painfully felt). There was ZERO peripheral vision. Just a total and complete flood of bright red for that instant. My vision in that eye slowly returned over a period of hours.

I would not be surprised if indirect 'beam scatter' radiation from impurities in the water sends uncomfortable laser radiation into the made-for-the-dark sensitive eyes of sharks and other marine animals even when the beam is not directed at the eye.

Wow, you guys see these things up here?!?!?
When and where?

Joshua Smith · Post by **Joshua Smith** » Sat Feb 16, 2008 6:25 pm

I saw 3 last year; all of them were at Alki Cove 2. They're all over the Sound- maybe not so many over in Hood Canal, but they see them there once in a while, too. Here's 2 reports of the ones I saw with Calvin:

The first vid is of an ~8 foot female, the second was a ~12 footer!
