An Australian fisherman was sailing his small leisure craft back to shore the other day when he ran into a so-called "bait ball" of small fish, being attacked by dozens of sharks. The big predators were in a feeding frenzy.
Note the casual way he talks about his boat being bumped by sharks several times. Me, I'd have been getting the heck out of there as fast as possible! I've seen (off Seal Island in False Bay near Cape Town) how fast and brutally sharks rip apart their prey. I'd want to make as certain as possible that I wasn't near enough to be even potentially on their menu!
