Basking sharks and Lampreys (Lampreys on SHARKS!)
Вставка
- Опубліковано 7 тра 2012
- In 1998, Jonathan made a remarkable discovery about Basking sharks, the second largest fish on Earth. While diving with Basking sharks in the frigid waters of the Bay of Fundy, Jonathan saw parasitic lampreys on the backs of the sharks. This had never before been documented, so he returned the next year with a shark biologist and a lamprey biologist to attempt to recover living lampreys from the backs of Basking sharks. They didn't think Jonathan could do it. Wait until you see what happens!

**********************************************************************
It's a beautiful summer morning in Atlantic Canada. As the sun rises at 5 AM, the fog blows off the water and I head down to the dock to meet my ride.
We begin loading the "Mary O", a research boat from the University of New Brunswick.
Shark biologist Steve Turnbull is aboard, hoping to gather firsthand proof that Basking sharks in the Bay of Fundy have lampreys on them.
Also aboard is lamprey biologist Dr. Mike Wilke, who has brought all kinds of scientific equipment to test the lampreys…assuming we find any.
We're heading out into the middle of the Bay of Fundy--a long stretch of water between mainland Canada and Nova Scotia. It has the highest tides in the world and a huge amount of plankton.
Plankton is food for many animals in the ocean. The word plankton means drifter, so anything drifting is planktonic. These tiny copepods are planktonic crustaceans, smaller than a grain of rice. More than a quarter of million of them could fit into a coffee cup. They might not seem like much…
But they are the main food source for the Basking shark, which swims through the water with its mouth wide open to filter them out of the water by the millions.
Basking sharks are the second largest fish on Earth, reaching 45 feet long. That makes them longer than a school bus! That is one big shark! But since they feed only on plankton, they are no threat to people at all. In fact, a Basking shark's throat is only the size of a grapefruit. It can't swallow anything bigger than that!
We see something on the horizon and start heading that way. Soon we get closer and the shark dives out of site.
Back to the binoculars. Basking sharks are big fish and they don't need to come to the surface to breathe like whales. So you have to get really lucky to find one close enough to the surface that its dorsal fin sticks out of the water. Without that, we have no hope of finding any.
At last we find another shark and manage to sneak the boat up nearby. The shark is just cruising slowly, feeding on the plankton.
We jump in the inflatable and head out with cameras to see if it has a lamprey on its back.
We approach as close as we can, and roll off the boat.
An enormous shark passes below us in the green soupy water. The thick plankton makes the visibility bad, but that's why the sharks are here. It's pretty spooky.
I see a lamprey on the shark as it goes by, but I am not deep enough to grab it.
We decide to bring the Mary O up alongside a shark. They seem to react a lot better to this than the inflatable.
On the next attempt I jump into the water and get some good video of the lampreys on a shark. I'm incredibly excited that I have proof for the biologists that these sharks have lampreys on them. Now the hard part: our team takes turns trying to grab a lamprey and get it to the surface.
I manage to get one with one hand while holding my video camera in the other.
Meanwhile, Mike begins getting his apparatus together. He wants to find out how the lampreys can handle the toxic blood of the shark.
Sharks have a lot of urea in their blood which is why biologists used to think that sharks could not have lampreys on them.
Lampreys have a terrible looking oral disk instead of a jaw, used to drill a hole in a fish and drink their blood, like vampires.
If they are drinking the shark's blood, they are getting what biologists consider a deadly dose of toxic urea. So Mike wants to find out if they are really drinking the shark's blood, or just getting a free ride.
If they are drinking the shark's blood, how do they deal with the urea?
The lamprey doesn't seem very happy about being confined to a tiny little tray full of water.
With two lampreys aboard, we call it a day and head for the dock. Mike's research showed that the lampreys are in fact drinking the shark's blood and it turns out they have powerful kidneys that can filter out the toxic urea.
With all the hearts and responses he gives out, even on old videos, seems like Jonathan reads every comment he gets
Yes I do!
@@BlueWorldTV my whole childhood is this channel. Thanks for everything, Jonathan.
Anyone esle still watch the old vids cause of the intro? Soo good
This be an episode three of season one are u talking only the first two episodes ???
I just like the sea and science, that’s why I still watch the old vids
Yes
Way to go Jonathan! So impressed that your discovery was noted by marine biologists and assistance and capture of the lampreys was so successful. You have one of the best jobs in the world. I love your channel. Thanks so much for your dedication and love for the blue world. 😊👍
Thanks for watching!
When he pulled of the third lamprey the shark, it agreed to put in a good word for Johnathan with his friend the great white..
Who now has a special pass to dive in all waters with the blessing of the sacred order of the clasper.
Wow you actually found one of 300 of those whales left? Damn that’s impressive
GVTheRedStar 2!
???
lily li r/whoosh
@@ItsMe-mq5on why are you wooshing here?
what whales
A basking sharks throat is only a big as a grapefruit?😳 I did not know. I’ve looked up basking sharks many times in the past and not once did that piece of information come up. Thank you for sharing this!😁👌
A lot of sharks throats are. They have huge mouths and small throats
I still watch the old videos.
I love blue world TV I am a big fan 😂
Joshua and Alexandria Im a small fan 😂
Same
Jk im a fan not the biggest fan😂
Very interesting relationship between this blood eating animal and the toxic blood of the shark. I learnt something new! thank you.
Wow Good Job Jonathan bird. You Have Made a DISCOVERY!!!!!!
Oh my goodness I just realized that you don’t actually talk while you dive! That’s just so dumb that I think that but that’s just how well you talk and that illusion is sooo great like basking sharks have to be my 3rd favorite sharks my first is the Thresher Shark and 2nd would definitely be the Greenland shark. Thanks for clearing my Sharkaphobia when I was a kid.
I talk when I dive all the time, but nobody can hear it thankfully!
THANKS FOR THE INTERESTING INFO ON THIS VIDEO, GREAT FOR THE WHOLE FAMILY TO SEE & LEARN ABOUT BASKING SHARKS! KEEP IT COMING!
Yeah! Basking sharks are really extremely rare
Johnathan:where are they?
*Shark sneaks up on him*
HERE I AM
BOOGA BOOGA BOOGA
7:40 it is so awesome to see the excitement of scientist during a new discovery
Wow!! What a great privilege it it must be to be the one who helped open up even more information about the “Blue World”!! Congratulations on your find!!! 👍🏼👍🏼 And, as usual, an awesome and amazing video!!!
Basking sharks have always looked funny with their small eyes and large mouths. The infamous "shark pog".
Man this guy's video is absolutely legendary I've been seen him in like 4 years but I love his content I recently rediscovered his channel just cause I wanted to see his videos and see what he's been up to for the past few years
Hey, welcome back!! Still here!
@@BlueWorldTV thanks. Also to clarify I love you video. (I discovered you through your videos on sully and the Vandenberg) but I left you for a few years. Until I decided to return to see your videos and see what you've been up to.(also what happened to your videos on the guardian and stargate blue holes?)
If I ever get my driver's license and pay off my debts I'm moving somewhere near water peace and quiet sort of private like a light house
First - Canada 🇨🇦 rules!
Second - Wright whales - soooo cool
Third - no wonder people thought there were sea monsters with basking sharks cruising near the surface! That was just surreal.
And thats why i love watching BlueWorldTV we learn something everywhere and everyday
SHARK POG
Oh look planktons do look like Mr. Krabs's rival
Lampreys freak me out :O
Bahari Brizo me too
same :O
With this older opening when he says welcome to my world they point downwards and I can’t help but think “hi I’m Jonathon bird, and welcome to my 3 cubic meter patch of water”
He old intro Johnathon sounds like he is in a rush trying to get to his dive🤣
Wow! Thank you Jonathan!
MY FAVORITE SHARK
Your videos remind me so much of Jacques Cousteau. Back then my sister used to subscribe to his books and I had the privilege of reading them until we could watch his series on television. Then came along UA-cam it became watch on demand. I believe I came across your channel probably due to the AI at some point during The Pandemic and I’ve been hooked since. Keep it up, I along with many of your subscribers are fascinated. Thank you
Thanks for being here!!
I remember watching this video as a kid and being mesmerized by this, it quickly became my favourite channel as a kid and I just remembered it. The nostalgia is so real
I'm glad!!
Same
Awesome video, I’m from NB and have visited the Bay of Fundy a lot, it’s a very pretty region
This is so cool!
I've got news for Jonathan Bird: Gavin Maxwell wrote a book called Harpoon at a a Venture, in which he chronicles the commercial hunting of basking sharks in the UK, in the 1940's. And Maxwell wrote about lampreys on the backs of Baskers then. Sorry Johnny!
First I have heard of that. I'll have to find that book! Thanks for the heads up! Apparently none of the shark biologists I talked to had heard of it either, because they didn't believe me.
@@BlueWorldTV Wow, wasn't expecting a reply! Sorry if it sounded a little gruff. I meant well! But yes, it's an old book but reprints are available on Amazon and ebay. Maxwell wrote a very famous book years later called 'Ring of Bright Water', which was later adapted for Hollywood.
Anyway, I'm actually rereading Harpoon At a Venture, which is why I felt obliged to mention the lamprey issue! I'm sure you'll enjoy the book. 😊
Lampreys and hagfish are the only animals classified as jawless fish.
Jonathan was kind enough to send me the link to this video as I've been a loyal supporter of BlueWorldTV for over 3 years now and it has been an amazing time! I know of no other SCUBA diver who has the passion, joy and infectious personality that Jonathan has! Really appreciate the link Jonathan!
You're welcome!
I love seeing new animals. Do you?
I seen it before and I loved it!!!
Seiko Royal Oak! 4:40
Maybe Lampreys have Basking shark Uber!? 😂😂
You know what? I must say Jonathan you're actually full of luck! 😊
I love your channel
This is amazing!
Shark Pog.

Pog
so the baskin shark is a harmless megalodon
I luv this show/video
Have 2 story’s about these giant sharks. Both occurred on the north coast of Northern Ireland by Portstewart and Portrush
1. I was doing 2 dives with my local dive company on their boat. We’d just finished our first dive and were fitting our new tanks to our BCDs Whalen suddenly a giant fin slices through the surface of the water. It glides under the dive boat, it’s dorsal fin hitting the hull. My dad was onboard and videoed it on his camera and saved it on our computer.
2. I was sitting in a restaurant by the sea looking at the beach when not one, not two, but THREE basking sharks appeared from the sea in the bay. Everyone was fixated on the sharks as they swam gracefully. It was incredible
Keep up the vids history on you 👍🏼
Lucky shark! Thanks to the team 😄
Shark pog
Great job! Must’ve made ur day!
When are you going to do a new video because I love your videos
I’ve been watching since I was young when I was *6* I was the shark nerd in my class 😂
😎
So Awesome 👍👍 Not just anybody can swim with these big beautiful sharks💕
Lisa Pecaskie literally anyone can
I have Proffesor Turnbull for zoology this year, it must have been such an honour to work with him! :D
Tell him I said hi!!
Wow great video great information You people are awesome you're awesome
Ooooh!!! I don't think I like lampreys!!! Sharky xxx... Lampreys seem to be to sharkies what leeches are to us, YEUCH!!!
i'm curious-if you're diving, and you're low on air so you go to the surface, but you won't have enough air for the time it takes to decompress, which is more important;
stay and decompress until you're out of air, or
just go up anyway?
what would you do in this situation?
aand, as a megalophobic (fear of big things), these are my least favorite animal. :'3
also DANG, your editing is GOOOOD :D
Well, if you run out of air, you die. If you go to the surface without decompression you MIGHT die but you might not if they get you to a recompression chamber quickly, or you can swap tanks and get back in fast. So I would go to the surface.
ah, i see. ^^ interesting and kinda scary xD;
If your low on air take a decompression stop or a safety stop but if your really low on air just take a cesa
How am i just discovering this channel? Going to watch all of them! Trying to go into marine biology!!
Welcome to the channel! You have a lot of catching up to do! LOL!
Back in the 60s, French photographer Anita Conti took pictures of a basking shark that had so many lampreys on him that he could barely swim; he was obviously dying.
Do you know where that was?
WOW 1 BIG SHARK 🦈
These are some of the few sharks found off of Scotland that what I heard
Basking sharks!
Can you make a video on Killer Whales?
Geetanjali Sharma that would be cool.
PZ 13 true, true
There has been no record of wild orcas killing people 🤦♂️
KILLER WHALES STINK
it's not! But they sometimes attack.
Loved it😃😃😃😃‼
Glad you like it!!!
Wow well done
Thank you! Cheers!
We are currently being over run with lamprey eels in all the local rivers of Northern California. They are terrible at the fish hatchery for the spawing salmon in the Feather river in Oroville CA
That's weird. I'll check that out, thanks for the heads up.
Cause this video, I have an inspiration at 2 Am for my investigation work of biochesmistry. Very thanks!!!
(I speak spanish, sorry if I say something wrong)
7:20 -- The lamprey is just GHASTLY.
Happy 8 year aniverys
Dude i love ur life ❤
Nice video
Does that mean that jelly fish are planktonic
Yes they are.
yaaay jonathan discovered smthng
Awesome! So glad YOU got that discovery..fitting and you deserve the excitement and recognition. And all your fellow Blue people!🙏💙🦈💐🏆Fab year for my fam too. My first grandchild was born.😍👶🏼 So with this type of research you don't have to kill the animals to learn. Right? Fabulous! Is this a discovery that might help in human research as well?🤔
As a matter of fact...this spawned research on Lampreys to learn how their kidneys can work so effectively and it shed light on ways to improve human kidney function!
I’m your biggest fan
i thot that basking sharks are not that big
Whoa
i dont think spooky is the word id use if i saw that swimming under me! You know it's really interesting but you can see on the Sharks back all of the scars from lampreys Onnit see all those circular little scars. Although it makes me think could that be the reason why the basking sharks occasionally will breach and sometimes they'll deliberately half Beach themselves and like roll around in the surf zone wonder if that's why and you're trying to scrape the lampreys off
Drake Mcfee it's called breaching when they breach the surface and smack down on their sides and back to get lampreys and remora off their bodies.
when i grow up i want to be just like you mr jonathan bird
Aw! Thanks!
Listen. And I say this in the most loving way possible. Basking sharks just look So Dumb. I love them so much. Look at their tiny eyes and their giant, expanding mouths. They're so stupid and I adore them so much
Hi you no that those are the leeches of the sea
But you still good diver.i love
to dive
If its ur world ur nickname is Poseidon
is it possible to make another video about basking sharks? this is the only video about these amazing sharks. we never got to see footage of a basking shark feeding with its huge mouth open. hopefully one day there will be another video all about basking sharks
I'll work on it!
Can you reproduce the northern right whales in like captivity or some kind of research center???
They are BIG so that would be quite an undertaking!
I think it’s better when at first, the video starts so does the theme music, too?
It has a similar instance of amusement.
Basking shark mouth look like it would be able to fit and person your size, if assisted?
Lamprey seem bothersome. Poor whales.
Thank you blue world!
Shark not whale
Remora underme
3:11 45 feet long, thats that same size as a greyhound bus
a school bus is 35 feet
I LOVE YOU !!!!!!!!!!!!!!
wow
Anyone else back here in quarantine???
all shark like blacktip shark, whitetip shark, porbeagle, blue shark, sand shark, thresher shark, hammerhead shark,
bull shark, goblin shark, mako shark, megamouth shark, tiger shark, basking shark, whale shark,great white shark and megalodon
I like sharks
Apparently they are in norway.. True???
Oh Jonathan? You are so dang handsome. We all were more beautiful back when we were young punks. Happens so quickly. You and Christine are holding your youth well. Hubby told me how old you are now in 2021 piecing together clues and I am impressed! Must be all that 'moisturizer' with sea salt and kelp. Grins!
LOL. Thanks! The biggest challenge in the last year has been trying not to eat too much!
Getting those lampreys off helps so much. Thank you so much.
ウバザメとかジンベエザメって、プランクトン主食でよくあんなにでかくなれるよね。
how do the lamprey find the shark? for they breed in the rivers?
That right there is a very good question!!
Rarest whale in the world is just a little side note, lol.
Yes, and highly protected!!
I thought those lamprys would be bigger
