Hi, I’m Jonathan Bird and welcome to my
world! The Blue shark. Implicated in attacks on shipwreck
victims, and known to possess a mouthful of razor-sharp teeth. This vicious-looking fish has a few surprises
in store for me as I prepare to leave the protected shore of Rhode Island and venture
into the realm of the Blue shark. I’m on board Snappa, a shark diving boat
in Rhode Island run by veteran shark fisherman Charlie Donilon. In recent years, Charlie
has turned from fishing for sharks to diving with sharks. We leave the harbor in the early
morning because we have a long way to go to find the sharks. After heading straight out for 3 hours we
can finally stop. Blue sharks are pelagic, that means they live
in the open ocean, so to find them, we have to travel here forty miles from the coast
of Rhode Island and as you can see there is no land in site. The first thing we do is drop our shark cage
into the water. The cage will protect us from the sharks when we go diving. Next, we need
some sharks. To attract sharks to the boat, we use something
called chum, which is basically ground up fish parts and it looks like this. This bucket
if filled with chum. And we’re throwing it overboard to create scent trail in the
water. Basically, the current carries the chum off and the sharks smell it. And then
they follow the smell back to the boat. And when they get here they find Charlie and he
throwing nice little bite size morsels of fish over the side to keep the sharks interested. Within only minutes, the incredibly sensitive
noses of the sharks have detected our chum, and convergered on the boat. JONATHAN: That’s a nice…Look at him right
here. Come right over back of the boat. Look at him see him his blue back? Oh yeah! That’s
a good looking eight footer. Scientists don’t know very much about sharks,
but they do know that blue sharks are incredible swimmers. Often traveling thousands of miles
in only a few months. And the reasons they know this is because of these shark tags.
If you put a shark tag on a shark in Rhode Island and the shark is caught thousands miles
away you can tell from the tag where it came from. Charlie volunteers to tag sharks for the National
Marine Fisheries Service so they can learn about the migration patterns of Blue sharks. The tag is a tiny piece of paper with a serial
number rolled up inside a water proof capsule and attached to a barb that goes under a shark’s
skin to hold it in. CHARLIE: This is a shark tagger. Charlie is an expert shark tagger. He’s
been doing it for 20 years, and today I’m getting a lesson. CHARLIE: We are going to attach it to our
tag pole here… JONATHAN: OK… The tag goes on the end of a pole. I’ll
use the pole to stick the tag into a shark from a safe distance. CHARLIE: And it’s going to trail behind
the fish… But you still need to get the sharks within
reach of the pole, and to do that, we’ll use some bait.
We have a piece of fish on a line with no hook. What we’re going to try to do is get
the shark to bite it. And sometimes they bite it so hard they won’t let go and you can
pull them right out of the water, but since no hook it doesn’t hurt the shark. JONATHAN: Oh we got one now! CHARLIE: It’s got it JONATHAN: WHOAH YEAH!!… Nice one! Sometimes the bait brings them a little too
close! It’s hard to aim with all that thrashing
going on, but now is my chance! JONATHAN: Did I get him? All right, I did
get him! CHARLIE: Now let’s see if it’s a male
or female JONATHAN: Outstanding. That was pure luck. I know it looks painful, but thick skin on
the shark’s back makes the tag barely noticeable to the shark. Now we fill out a card that we mail in to
the National Marine Fisheries Service. The card has information about the shark that
we tagged, such as the location we tagged it, the sex, male or female, and approximate
length. Some of the sharks that Charlie has tagged
have been caught as far away as Africa, a distance of over 2,500 miles! Blue sharks
can really get around! Now, I’m too excited to stay on the boat
any longer. I need to get into the water with the sharks! I put on a thick wetsuit to protect me from
the cold 60 degree water, and then take the plunge. Immediately, the sharks notice me and come
over to investigate. I head straight for the cage and get in. But
from inside, I can’t see the sharks very well unless they come really close. So, forget
this cage! I’m going out to swim with the sharks in the open water! As soon as I’m out in the open, the sharks
closely approach me and seem to have an intense interest in my camera. They bump their noses
into the lens and seem confused by it. Believe it or not, all living things put out tiny
electrical impulses. Sharks have special electrical senses that can detect the electrical impulses
of living things. They can tell that the camera isn’t food,
so they don’t try to bite. But the camera does seem to peak their interest. The sharks are coming so close that I can
actually touch them. They seem so engrossed in the electrical signal
from my video camera or by the chum in the water that they don’t seem to mind being
gently touched as they swim by. It’s easy to see where the blue shark gets
its name. It has a gorgeous deep blue color on its back that probably helps it blend in
to the ocean. CHARLIE: I don’t see him at all. While I’m having fun underwater with the
sharks, Charlie is still trying to tag a few more. This shark grabs his bait and takes off with
it….right between the bars and into the cage! This is a big shark but it still fit through
the camera port in the cage. Now it can’t figure out how to get out. I’m afraid the
shark will hurt itself, so I have to see if I can help…without getting bitten. I open the door and try to lead the shark
out, but it is thrashing around so much that it doesn’t realize there is a way out. I have to be very careful here, because the
shark could feel cornered in the cage and it might interpret me as a threat. Finally, I have to grab it by the pectoral
fin and yank it out! All I can say is, I’m glad I wasn’t in
the cage when that happened! It might be safer on the outside!! By the end of the day, we manage to tag 5
sharks. Who knows where they might turn up and when. Swimming with blue sharks showed
me that sharks are not evil and dangerous. They’re wild animals and unpredictable,
but certainly not mindless killers. I can’t help but admire these beautiful and streamlined
predators–Blue sharks in a blue world.

  1. I have a question. if sharks have to keep swimming to breathe, how do they sleep? do they sleep while swimming? my mom said that maybe half their brain goes to sleep but I want to know for sure

  2. Jonathan, I have a question for you ; which sharks would be your pick that could possibly consume shipwreck victims who are dying/dead then? Grey Reef Sharks? Oceanic Whitetip? I know from your videos that none of them would be interested in eating you when you are healthy but maybe things change when they see that you are dying anyway?

  3. Looking at the long blunt noses on these sharks it appears to me that the blue shark is the Jimmy Durant of sharks.
    I kept thinking one of those sharks was going to say Ha cha cha cha cha cha cha .

  4. List of sharks i want to see on BlueWorld

    Goblin Shark–alien-sharks-goblin-shark.jpg (even if it freaks me out)

    Frilled Shark (even if this one also freaks me out)

    Mako shark

  5. There's nothing vicious looking about the Blue Shark … Great White's , Hammerhead's & Bull Sharks , those have predatory looks , the Blue looks like an sea arrow rather than swimming teeth , i guess looks are deceiving !

  6. Looking forward to the day people KNOW sharks, when even the idea of culling will be an ugly and shameful thing of long past.

  7. notice the lighting on all these friendly shark videos, this was done in late morning, noon or early afternoon. they've had breakfast and aren't thinking about dinner yet. never go in the water in early morning late afternoon/evening or at night

  8. Animals are indeed very poor creatures….☹️ Humans like to inflict so much influence on their natural habitat… Thanks for help that poor caged animal.

  9. Wait………Chum…… parts…..chum in a bucket………………where have i heard that before……Oh spongebob The chum bucket …..
    That means that ………OH OH GOD

  10. "Cage goes in the water, you're in the water, sharks' in the water."

    "Hooper drives the boat Chief."

    I would swim with blue sharks. They're cool!

  11. Today three of them.cornered my spearbuddy at that time he had no fish on… they were pretty agresssive until he injured one of them so they just vanished… sometimes they see you as food if they come in as a pack

  12. All the scarring on the shark's back near the tag barb make it appear as though they have been tagged many times, but the tags often get ripped out from their flesh.

  13. Blue shark: the ocean is all about meeeeeeeeee because it’s blue and I’m a blue shark and my name has “blue” in it

  14. I’m studying to be an engineer but have always wanted to do this kind of thing, I look up Jonathan Bird Wikipedia and he was an engineer before being a diver…

  15. Reminds me of that leopard seal in antártica that tried to feed the deep sea diver with his huge underwater camera penguins

  16. Blue sharks, the most beautiful and graceful fish. Like svelte blue rubber aeroplanes. With big puppy dog eyes and no nastiness and meat and teeth hanging out like your usual scarred up white shark.

  17. Blues sharks are my absolute favorite I don't get nearly enough publicity or camera time would love to see a whole special on them during Shark Week

  18. I wish I could touch a blue shark and even hug one. Those creatures look so adorable with those innocent looking eyes.
