Since feeding sharks is illegal in South Florida
waters, Jim Abernethy runs shark tours from Palm
Beach to the Grand Bahamas. Plenty of top drawer
photographers wanting shots of hammerheads
and tiger sharks are his loyal customers. They all
say Abernethy knows his sharks.
But on Jan 25, Abernethy was attacked by a
  reef shark in one of those busy shark moments,
  leading to a ride on Coast Guard helicopter to
  St. Mary's Medical Center with a healthy bite to
  his arm. The attack happened about 18 miles
  north of West End where Abernethy was leading
  a week-long shark excursion. According to witnesses,
  when Abernethy got back on the boat, he
  was bleeding profusely. He needed stitches, but is
  expected to recover.  
Abernethy, himself, is not his first victim.
  In 2008, an Austrian tourist died when he was
  mauled by a shark during an excursion sponsored
  by Abernethy's company.  
Abernethy's trips are controversial. Many
  in South Florida say he should not be feeding
  sharks, as they have become much more dangerous
  due to humans feeding them. "They're not
  highly intelligent animals to begin with," Jason
  Doty told TV station WSVN, "so you're down
  there diving, and if you're feeding them, they
  think divers are food. When we're out spearfishing
  they're super aggressive with us, but they
  used to not be."  
Abernethy released a statement saying: "Thank
  you for your concerns and well-wishes, I'm going
  to be fine. I've spent the last two decades of my
  life in the Bahamas with the sharks that I love.
  Today's minor incident will not deter me. I plan
  to be back out to sea in a few days."
