I've seen this multiple times in South Africa and Guadalupe (this is footage I shot in Guadalupe)..A seal swimming around the boat and cages, almost leisurely, while multiple white sharks are around. Sometimes they follow the sharks, perhaps playing, perhaps staying away from the front end of the shark...but I've never seen one pursued, much less killed. Is it that hard to catch a seal if it's not an ambush? I used to think "yes", until I saw this...http://www.whitesharkvideo.com/shark-...
