The Deep has some awesome photos of deep sea creatures, many of them taken by MBARI, and featured in Mysteries of the Deep (not to be confused with the National Geographic series of the same name), one of the shows at Monterey Bay Aquarium.
Check out the impressive gallery on the book's site (the link is on the bottom right corner).
I recall when they first found the 'Dumbo Octopus'. Now somebody's named it 'Dumbo'. They could have done better. The discoverer must have had a shitty name. The variety of cephalopods is astonishing.
