This is an interview that appeared in DIVE Magazine in the UK recently. The main topic is an encounter I had with a juvenile sperm whale some years ago, one which left an indelible mark on me, fortunately in a good way.
Sperm whales are the largest carnivores on the planet. They have cavernous mouths with big, big teeth. I got a close-up look at both the mouth and the teeth, as Colin Doeg describes in the article (304kB).
Just reading the text, you might get the impression that I was calm, cool and collected. In reality, with an 11-metre predator literally on my fins, I was pissing in my wetsuit (to put it in an understated, PG-rated manner).
