What’s Driving Shark Attacks in Recife? | SharkFest


[dramatic music] NARRATOR: Along a roughly
25-mile stretch of shore, there have been
more than 60 shark attacks since records began
and almost half of them fatal. In fact, this small area
accounts for almost 50% of recorded attacks in
the entire continent. As a result, it’s earned a
chilling designation as South America’s deadliest coastline. [water splashes] ANDRE AFONSO: In
Recife, the shark attack problem is very serious. It’s probably one of the
most dangerous cities in the world for having a swim. NARRATOR: Residents
are at their wits end. I want to know why it
happens here and always here. NARRATOR: In an attempt to
prevent further attacks, authorities banned
surfing in certain areas, and signs line the beaches
warning of the dangers of entering the ocean. But the only real way to
stop this bloody barrage is to figure out how it started. FABIO HAZIN: It’s
absolutely crucial to find the cause of the
problem because, if we don’t, we can’t build a solution. NARRATOR: So what’s driving
this terrifying onslaught along with Recife’s shores? And could other coastal
resorts be next? According to former
instructor Fernando Clark, something makes diving
in this area unique. And it hides deep
beneath the waves. Recife is the shipwrecked
capital off Brazil. NARRATOR: The area
around the attack zone is home to dozens of
sunken vessels, some dating as far back
as the 16th century. But according to Clark,
these ill-fated ships are more than just rusty relics. FERNANDO CLARK: The
shipwrecks become a reef completely full of marine life. NARRATOR: Fish,
crustaceans, and mollusks call these down vessels home. But it’s what these marine
inhabitants attract that could be problematic for people. FERNANDO CLARK: When you
go shipwreck diving here, most of the time we
see a lot of sharks. NARRATOR: The presence
of sharks near shipwrecks is a phenomenon that can
be seen elsewhere too. In the US, sunken
vessels along the shores of Oregon, Florida,
and North Carolina are inhabited by
these predators. The sharks are
attracted to the shipwreck because of the food. NARRATOR: So could
the wrecks of Recife be responsible for luring
dangerous predators near shore where people are? Clark says the answer comes
down to the species of shark he sees most often on his dives. To demonstrate, he plunges
into the shark-infested waters. [water splashes] [gentle music] Before long, he spots just
what he’s looking for– nurse sharks. [energetic music] Nurse sharks are
bottom dwellers, attracted to the
crustaceans inhabiting Recife’s sunken ships. Measuring up to 9 feet,
they possess powerful jaws with serrated teeth. And, worldwide, they
have been implicated in multiple attacks on humans. So could nurse sharks be
responsible for Recife’s spike? Dr. Fabio Hazin is one
of the lead investigators trying to get to
the bottom of what’s happening along this coast. And when he analyzes the
details of each incident, he comes to an
important conclusion. FABIO HAZIN: Nobody in Recife
has ever reported being attacked by the nurse shark. So the shipwrecks are not at
all to blame for the attacks. NARRATOR: Instead,
Hazin’s analysis points to two other suspects,
both of which have reputations for
attacking humans. The first one is tiger sharks. NARRATOR: Tiger sharks can
grow up to 18 feet in length and weigh in at 1,400 pounds. Known for their
undiscerning palates, they’re equipped with
sharp, serrated teeth that allow them to
rip through seabirds, turtles, and even people. [dramatic music] Perhaps even more imposing
is the other culprit Hazin implicates in the spike. And that is bull sharks. [energetic music] NARRATOR: Bull sharks bite
with the most force pound for pound of any large shark. They are fast and aggressive. And they’re often found in the
same shallow coastal waters as humans. So it appears
tigers and bulls may be responsible for the spike. The question is, why?

  1. National Geographic when you write a question as your Youtube video title please make sure you have an answer to that question, that's the reason why people clicked on the video. Don't wait until 5:40 to be like "I dOnT KnOw "

  2. Well, isnt this already studied and found related to a slaughterhouse letting blood in the water from the river? It attract shark and incrises the encounters!

  3. NatGeo: Here's a video with a question in the title and it ends with no answers.
    Me: Am I joke to you?

  4. That was sort of a dumb video. I mean sure, they explored possibilities I guess. But they didn’t make any progress whatsoever toward answering the question they set out with.

  5. The reason for shark attacks in Recife could possibly be found on the ocean floor. What are your thoughts on the attacks in this coastline?

  6. It feels like the tone of this show is geared towards manufacturing fear towards sharks. Is that really what National Geographic should be going for?

  7. This whole video just felt like scare mongering. No actual information given, this did not feel like an informative National Geographic video. Thumbs down 👎

  8. According to recent Ugandan studies humans who get into the ocean have a higher percentage of being attacked by sharks than humans who do not. It's a scientific fact.

  9. I watched another documentary on the increasing shark attacks in certain areas and the most prominent thing is cage diving. In many places where cage diving is a tourist attraction they lure the sharks towards the humans in the cage with food, that makes them more aggressive and hostile towards humans and once a human isnt in a cage anymore, well done deal

  10. Greetings you fabulous Earthlings and Happy Sunday!!! 👋👽I bring Keto friendly cookies to all you friendly Earthlings 🍪Don't mind me, just cruising by:::::::::::::::::🛸

  11. No no no you have it all wrong. It’s Bruce and his pals, they use these shipwrecked boats for their ‘little get together’. Dory is a fully pledged member now by the way. Fish are friend now food.
