Shark sighting

[mkaug]

I've heard from seperate people that they sighted an unusual shark in our waters. Unusual in that it seems to not to be a dogfish species or a sixgill.
Anyone have any info? One man told me it was almost like a blue shark.
Interestingly enough I have also been told by a diver that his computer logged a temerature of 61 degrees, I wonder if there is a corrilation.

Where are these sightings happening? There are other sharks in our waters but aren't usually spotted b divers because they are deeper or further out than we dive.
Temperature changes, of course, effect a whole lot of things. But 61 degrees at what depth?
