I was sent these images by a work colleague and thought they were worth sharing. According to the introductory text, they were taken by a 'famous photographer' in California, with a 'high resolution' underwater camera. Hmm, typical interweb attribution, but I think the images speak for themselves. What intrigues me is the way that so many of the dogs look like those weird deep-sea fish that were the stuff of childhood nightmares when I first saw them in a copy of National Geographic at the age of about six.
Here you go, click to enlarge. Bonkers Dog would have loved this.
