That was from a submersible, sharks were drawn in with bait.
I've six one sixgill, at Cove 2 right off the Seattle waterfront.
I've dived with nurse sharks in the Caribbean, and white and black tipped reef sharks there and in Maui. Nurse sharks in Australia. Hammerheads in the Red Sea. Wobbegongs in Australia, and horned sharks in the Catalina dive park. I think we saw some Lemons during the shark feeding dives in Tahiti (I was busy looking at porcelain crabs).
But the best was the Thresher off the Brothers in the Red Sea.

What was the approximate depth (if you recall)?

Thanks. I wondered what depth (due to the temp/light conditions) they were more likely to be found at in those waters. I know they're in all the oceans and I've heard of them being sighted off Bermuda and it's always been by sub but I hadn't heard the depth figures mentioned.
It makes sense though. In those waters some depth is required for temps and light (dark) conditions to be in the appropriate range I would imagine.

As you move to higher latitudes the light hits the water at a greater angle and deeper organisms are found shallower. In the arctic regions we see things diving that we only see from submersibles in lower latitudes, especially jellies.
The water temp changes as well
as in temps close to the surface aren't that much different than the oceans bottom. I hadn't thought about the light angle however.

Light level is the cue that controls the depth distribution of many marine organisms.
Temp as well for others though...correct? The light levels aren't that different between Washington and Northern California but Ratfish are common here at recreational depths but aren't in Northern Cal.
Sixgills are bottom feeders and even around here aren't out much at recreational depths except at night so night is night regardless of where you are. Sixgills aren't out shallow at night anywhere that I know of except where the water is cold (and viz limited of course).
