same thing with feeding FISH or Sharks while scuba diving.
Some divers carry food on their person to feed the fish so they can get a photo .Very bad idea because when you want to stop feeding they know where your hiding the fish ..they can smell it and they are coming to get it.
Iv been on Shark dives ..nobody I know hand feeds sharks ,what they do is drop a frozen bait ball with a float overboard .The fish ball dangles mid level as the sharks start to circle while photographers snap pics as they attack it.Smaller sharks come in first ,the really big ones stay farther away circling the fish ball.They are very cagey at first ,then move in to grab a piece.. Some places have condition them by gunnung the engine ,they hear that and come in even before the bait ball is dropped .Just like Pavlovs dog story….NEVER hide food on your person ,they will come and take it from you ,they smell it.Something else about the fish world is they dont tolerate cripples or injured fish ,they attack immediately and eat it. Thats why it smart to swim confidently and not splash ,struggle or look like your injured. That looks like an easy meal to them.. You can swim with sharks ,not a problem,really even touch them as they swim by.Just dont struggle and look like your injured. Have swam with black tip,white tip ,sand sharks, Nurse sharks without any problems.Never swam with a Great White ,never seen one….dont want to …above all dont feed them….
