Dave Ellifrit & Astrid van Ginneken MD PhD describe dorsal fin architecture and dorsal fin collapse in both wild and captive orca populations. Jeffrey Ventre MD, a former killer whale trainer, is filming, and David Kirby is asking questions. David is writing a 300 page non-fiction book to be released next summer by St Martin's Press. This interview is very informative. It was filmed in July 2011 on San Juan Island in beautiful Washington State. Astrid and Ken Balcomb are co-principal investigators for Orca Survey, a well known photo-identification study of the Southern Resident orca clan.
