This six-gill shark (Hexanchus) was filmed during a submersible dive off the northeast coast of Molokai at a depth of 1000m (3280ft). The 2 red laser dots are 6 inches apart, resulting in a length of about 18 ft for the shark. Great ecstatic live commentary by University of Hawaii Oceanography Professor Jeff Drazen!
