Nat Geo clip:
The Farallon islands are a group of jagged islands off the coast of California. They’ve become an area of great interest to shark researchers as great whites choose to spend time aggregating there. Author Susan Casey wrote a book about this called Devil’s Teeth: A True Story of Obsession and Survival Among America’s Great White Sharks (the book is well worth a read but take heed that the story is just as much about the author as about the sharks). Peter Pyle, a shark biologist on the islands, is referenced in the book as well as the clip.
I find this incident interesting on a couple different levels. First, we don’t often think of great whites succumbing to other predators, which seems to have fed into our fear of this creature.
Also, if you watch an associated clip: http://channel.nationalgeographic.com/series/wild/4669/Overview#tab-Videos/07504_00, it appears the orca may have exploited the phenomenon of tonic immobility, which I wrote a blog entry on previously. I’ve also written on the differing hunting behavior of orcas. Nature likes to keep us guessing….
