Extremely talented underwater photographer Jan Reyniers snapped this crumb off the sperm whale table while diving off the Azores. I would initially ID this as a fairly large specimen of H. atlanticus. Concur/Conflict? Edit: I found some additional work by JR, worth sharing... There's another fragment of, again, in my opinion, H. atlanticus in JR's 2009 online Azores portfolio at http://www.janreyniers.com Plus, for those of you interested in Great White Sharks and (mating) Sepia apama, look at the South Australia portfolio, pretty breathtaking.
