Fun fact about bull sharks: they’re the original Jaws. In the 1920s, there were numerous shark attacks near a town in New Jersey. Some of these attacks were actually on people swimming in a freshwater river. This leads marine biologists to the conclusion that it was a bull shark, not a great white
Yeah most of the attacks on the men of the USS Indianapolis were bull sharks and tiger sharks I think. Some may have been great whites, because some of the victims were bit in half. Any biologist on here?
Same thing with humans too. In an ambulance we give saline, not pure water. This is because the loss of ions is very serious and we can maintain liquids this way. Just giving water isn’t as useful and will just raise BP/blood pouring out of the body.
It's evolution. Our skin allowed animals to bring the ocean's salinity with us. The ocean's salinity fluctuates but on average is about 4x more salty than our blood. Another adaptation is being able to tolerate less salt because salt isn't as readily available the further you get from the sea.
@@jonasarnesen6825 in most cases but water follows ions better than water following a lower concentration of water (body in body compared to body vs. atmosphere)

Interesting - I had NO idea, but my eye doctor told me recently to stop getting the extra ‘moist’ daily disposable contact lenses, since they can actually make your eyes DRYER!! (Especially since I now have a rare eye disease caused by working with ‘safety testing’ of organophosphates, causing all of us lab techs to get poisoned by the pesticides, while working at Bayer CropScience for 15 years!!!)
They're designed that way because a percentage of the water in our bodies is 'salty'. They designed the lenses to be happiest in our tears. Huh. Kind of weird that thought came out that way now that I think on it a moment...
When I was 5 I watched Jaws for the first time and was convinced even though it wasn't in the movie that sharks were under the bathtub. 😂 made me always rush to get out.
"Don't expect to see whales in the river near your home - first of all because fresh water is a stressful environment for them" - and also, because the river near my home is about six inches deep!
4:45 About 6 years ago we had a 12ft beluga whale travel about 60 miles up river, stopping right outside my office. I watched it from my office window as it hung out in the area for about two days before turning around and heading back to the ocean which it thankfully was able to do.
Salt is used as a treatment for some diseases of tropical fish. I used to have a LOT of aquariums with tropical fish. I even had two fancy Angelfish, who had babies, something that is rarely seen in captivity, especially for a novice, like myself, who was not even trying to have a mating pair, so it was quite a surprise. Here's a little trivia about Angelfish. Both parents raise the baby fish, and they are VERY protective parents. When protecting their baby fish, called fry, they will go after your hand, if you have it in the water for any reason.
My mom let me watch Jaws when ai was like 3 or 5 or something around there and I was and literally am still legitimately traumatized from that. I was scared to take baths as a child and don’t even mention swimming in a lake or the ocean.
As a diver, spear fisherman and professional sailor i can tell you that you don't need to watched this movie to be afraid. When you dive a lot and in many world places different, it s better to be advised and to always check around. Shark are in them territory and they are hunters, as lions or others species you can we a prey for them and it s not because if the movie but because of the simple reality. Be eaten is maybe one of the worst fear for humans. The movie didn't help maybe but if you are living in the seas as me, don't think it s just in the movie and ut s safe..it s not. 🤟

The most dangerous shark on earth and the one that kills the most humans is the Bull Shark. It can live in either fresh or salt water. They are also the most aggressive and can grow to be huge.
This is mostly true. The national database that tracks shark attacks on humans and deaths caused by sharks, still lists the White Shark as the deadliest. But I agree that the Bull Shark should get way more recognition as the scariest fish in the water.
@@brandonfoley7519 The narrator implied that there is a tradeoff to Bull Sharks adaptation to fresh water. I couldn’t find anything, so I’m guessing WATOP made a mistake.
There's a golf course on the gold coast in Australia that has some rather large bull sharks living in the fresh water lakes.. they even have warning signs on the golf course to warn people not to swim in the lakes
Are they still there? I know they where captured by the pond when sever rains caused the near by river to burst it's banks and when the floodwaters resided the sharks ended up trapped in the pond. I wasn't sure if maybe there was a repeat flooding that released them or not.
in the marine community you can "fresh water dip" your marine fish (NOT INVERTS!) for about 10 minutes to remove external parasites and the fish will live.
Check out the Pacific Salmon, it is born in fresh water and goes to salt water for years and then travels back up into freshwater to lay their eggs and die. Taking this idea, I caught baby salt water fish and hard shell creatures in the fresh water marsh and was able to get them to live in fresh water ponds.
I've raised bred sold fish for over 30 yrs saltwater and fresh owned Strictly fishes in Las Vegas Nv. Brackish water fish crustaceans can survive longer than straight saltwater creatures in freshwater anything that wasnt already geared internally to go from salt to brackish to fresh that you transferred died without a doubt they did not live very long or thrive guaranteed. A salmon is genetically wired to go from fresh to salt back to fresh some other fish are also geared to do this during thier life cycle, some eels, some crustaceans. They must return to the sea in parts of thier life cycle if not they will die. What you just said is straight bs and goes against every scientific study done and knowledge we have.

With the tail over his shoulder he dragged it over the sand and through the pools of water trapped on the beach as the tide went out. It was as limp as a dead fish. A couple of pools later the shark suddenly came alive and tried to bite him on the leg. Boy was he surprised!

That is only true for recent vehicles. The ones with throttle body injection and carburettors could take the change. The petrol vehicles did not run that good but did okay. The diesel ones actually ran really good. There was a short lived engine that could take both fuels by Cadillac. It was a version of the 4-6-8 engine. I think it was called the crossover 4-6-8. It was made on a 350 cubic inch GM engine that was originally for petrol. Thus, the engine fared rather poorly. It later became the diesel 350 cubic inch engine. It was still built on the same petrol engine block. It just could not handle the added compression from diesel detonation.

They did explain it, their kidneys recycle salt while in fresh water so they don't dry out or bloat, it would be an unnecessarily large energy waste if they weren't living in coastal water
One rare species of bull shark live in only one Australia river. Plus coastal waters tend to be more brackish in spots than you thinks includes bays. Top 1 inch of oceans worldwide tend to be more freshwater but it’s a very thin fragile layer.
The 1978 movie Piranha is what got me. I swam in the Mississippi several times in the early 80s. When I recently found out that they discovered Bull sharks in Illinois area, wont be doing that again. People regularly catch Bull sharks south of St. Louis.
Growing up in the Fla Keys i was told and taught that if you had a cut on your body that one of the best things you can do is go swimming in the ocean so help heal the cut. And it will minimize scaring. So this makes total sense.
thanks about this type of content and research, recently i was watching videos about wolverines and remembering this channel I realized that they have never appeared here while the honey badgers are more popular than them. i know this comment is kinda off-topic but i just wanted to give my observation to probably see something of them in the future that idk.
I am from India, so never got to hear much about sharks, but crocodiles, alligators. Used to be scared of them whenever papa would take me to some river. I imagine it's the same phobia of shark for you people.
Imagine all you like but shark attacks in the USA are RARE! You actually have to find the shark. India: alligators, crocodiles, monkeys, dogs, snakes, cows, etc, etc, walk the streets and enter bedrooms!!🙄
I remember when u was a kid and learned about this subject for the first time. I thought it was super interesting. And then I loved reading about the different anatomies of salt vs fresh water animals that allows them to live in each type.
Perhaps an Octopus couuuld adapt to a freshwater environment fairly quickly with RNA editing. A process that wouldn't take millions of years, but instead hundreds. Then again this has only been found in Longfin Inshore Squid so far, but maybe an Octopus could directly edit it's RNA some day too.
Thumbnail: It is very heartbreaking to see such a majestic Tiger Shark reduced to such a humbling thumbnail!! (BUT, instead of a shallow video, was found an intelligent, well-researched & well delivered video!!! NOT the click-bait that I was expecting; a pleasant surprise!!)🙂
I did exactly the same. Saw the thumbnail and wondered what horrible anti shark nonsense is going to be in this video. So that was a nice relief watching it I do wish they would change the thumbnail, though
I have converted mollies to full saltwater many times so their definitely are fresh water fish that can switch over. In fact many use mollies as canary fish in a saltwater quarantine to watch for signs of ich or other diseases on new arrivals
I've always had an interest in bullshark I thought that salt water and freshwater bullshark were separate species and I always realize that the fresh water counterpart are alot smaller. The truth was that they're just offsprings afterall
Funny story about being afraid of sharks as a kid. Around 1984 I was a 5 year old living in Central Florida. Right around the time of Jaws mania. That was where I had got all my info of sharks. One day while swimming with my family at the beach I saw the unthinkable. A dorsal fin maybe 50 yards away. Being a 5 year old fresh from the experience of Jaws I did the only rational thing I could think of. I took off running out of the water screaming SHARK, SHARK. And to my surprise most people followed me out. Only then did everyone realize it was just a pod of dolphins. It was at that time I felt my mother's hand grasp my arm as she lead me to the vehicle. Apparently it caused a large scene and she was none to happy. So that was the end of the Beach for me that day haha
Seals and salmon are known to spend time in fresh water to rid themselves of parasites such as lice, which quickly detach themselves from the host in fresh water. I’ve witnessed this myself. Maybe this explains why some marine species are seen in fresh water environments. I have seen seals in Loch Ness ,Scotland- maybe this accounts for some of the ‘Nessie’ sightings! 🤣🏴
This is a common practice in the aquarium trade. Salt water fish are often given a fresh water 'dip' to eliminate parasites from being introduced into reef aquariums.
Bull sharks can turn up in all fresh water connected to the sea, here in Brisbane there are bull sharks in Carbrook golf course ponds, they got stuck there during floods.
More marine life could be moving into freshwater to escape certain threats in the ocean such as caution of ships,or more frighteningly pollution in the ocean like the islands of garbage.
Love the vids. The freshwater black Molly can live in a saltwater tank . Some goldfish too I believe . The black mollys are for sure 👍👍. So interesting .
Mollies are multiple closely related species. Some are brackish, some true saltwater. They have been bred back and forth to get characteristics into different species. The original black Mollies were from Mexico or Yucatan from a population which had black spotting and line bred for total black. These were fresh water, but still have the genetics for brackish water. Then they wanted the sail fin which occurs in the brackish and fresh water species (you can catch them in the mangroves in the keys). The point is that how well any specific black molly does in true salt water depends on the genetic line it's from.
I was a young one when Jaws hit the screen. I might have been too young to see it but being a boy and having a crazy fascination with horror films and stories, I felt invincible! I saw the movie on the big screen with a special audio system they had back then. 2+ hours later I walked home with my friends not knowing my life was about to change. From the time I got home and for months after, I was convinced that a shark was going to come and bite my ass off every time I sat on the throne to take a dump. Have a good laugh. I do now..
In Australia the shark responsible for most attacks is called a bull shark. A shark that is just as happy in fresh water as it is in salt water. Rivers can be dangerous.
Some saltwater aquarium keepers will dip new fish in freshwater. The freshwater will pop any external parasites before it does any harm to the fish. This helps prevent introducing parasites to the aquarium and keeps everything more healthy.
I used to be scared of tall buckets because I think there's electric power in there but now it's been 8 years since I was a kid so now I think the toilet has cobras inside
5:50 Hey a shout out to the Indian River Lagoon! I used to live close by over in Stuart. A couple times for field trips we'd go to the lagoon and I saw a couple skates and a dolphin while we were on a boat.
Ok so this is just a theory of mine. I'm an aquarium hobbiest (saltwater). There are parasites that marine animals get and some fish are just prone to certain parasites. Take saltwater ick for example....when fish in my tank get ick I give them a freshwater bath / dip. 3-5min depending on the fish. Which while they expand the parasites are expelled out of their gills. So my opinion is that fish know this too. Also, increased water temperature to 82-84 degrees helps kill the juvenile ick. Ocean water is colder than river water, so with these 2 things could be a factor as to why sharks swim up into freshwater.
All I know is that, having been a fish guy (tropical/freshwater fishes) for some 55+ years, many a freshwater fish have been saved using salt water treatments for multiple ailments over the years..... when I get new fish in from unfamiliar sources, the first thing that happens is they go into a saltwater bath prior to going in their isolation tanks prior to going into the community tanks.... I have tanks that have not been deep cleaned or had water changes in over 10 years..... as crystal clear and healthy as can be..... very, very rarely do I lose fish to any sicknesses..... they just die from old age... and THOSE get fed to my snappin turtle....
All fresh water in NZ except trout , travel as fry from the ocean , into esturys to adjust and find their water of birth . Salmon were introduced and only in one rive that I know of , possibly pike and koi - now a pest - otherwise it's long and short fin eels , and 13 species of Galaxid and other endemic native species , many of which are capable of climbing vertical surfaces if damp , or going cross country for a few hours .
When people in the saltwater fish hobby get corals and fish, it is a well known practice to dip fish and corals for well OVER 30 seconds in fresh water to rid them of parisites.

One rare species of bull shark live in only one Australia river. Plus coastal waters tend to be more brackish in spots than you thinks includes bays. Top 1 inch of oceans worldwide tend to be more freshwater but it’s a very thin fragile layer.
You make learning fun and interesting. If only school could have been that way. 😁
The 1978 movie Piranha is what got me. I swam in the Mississippi several times in the early 80s. When I recently found out that they discovered Bull sharks in Illinois area, wont be doing that again. People regularly catch Bull sharks south of St. Louis.
That's an awesome movie! I have it on DVD, and I'm glad to meet someone who actually remembers it's original premiere!
That movie still gives me nightmares
"Sharks, Whales, Orcas. How Unsalted Water Kills Giants"
Would of been a better title.
@@brandonfoley7519 That's what it was, originally. They changed it.
Growing up in the Fla Keys i was told and taught that if you had a cut on your body that one of the best things you can do is go swimming in the ocean so help heal the cut. And it will minimize scaring. So this makes total sense.
Man I love ur vids
thanks about this type of content and research, recently i was watching videos about wolverines and remembering this channel I realized that they have never appeared here while the honey badgers are more popular than them. i know this comment is kinda off-topic but i just wanted to give my observation to probably see something of them in the future that idk.
Bump
Love ur vids man
Amazing video steve😎💪. How many mugs of coffee do you drink?
I am from India, so never got to hear much about sharks, but crocodiles, alligators. Used to be scared of them whenever papa would take me to some river. I imagine it's the same phobia of shark for you people.
Imagine all you like but shark attacks in the USA are RARE! You actually have to find the shark. India: alligators, crocodiles, monkeys, dogs, snakes, cows, etc, etc, walk the streets and enter bedrooms!!🙄
I actually LOVE sharks.
I remember when u was a kid and learned about this subject for the first time. I thought it was super interesting. And then I loved reading about the different anatomies of salt vs fresh water animals that allows them to live in each type.
You remember when the op was a kid?
@@glockdude5472 they went to the same school🤣🤣🤣
@@glockdude5472 💀
This is amazing information. Thank you for the tips
i just love your videos They're always so interesting! :)
Perhaps an Octopus couuuld adapt to a freshwater environment fairly quickly with RNA editing. A process that wouldn't take millions of years, but instead hundreds. Then again this has only been found in Longfin Inshore Squid so far, but maybe an Octopus could directly edit it's RNA some day too.
It's interesting about RNA, new limbs can be grown this way, Salamander as an example!
“Sharks explode in fresh water”
*laughs in bull shark*
Thank you for this educational video🙏!
Unsalted sea water: Exists
UnsaltedSalt: "are you challenging me?"
Thumbnail: It is very heartbreaking to see such a majestic Tiger Shark reduced to such a humbling thumbnail!!
(BUT, instead of a shallow video, was found an intelligent, well-researched & well delivered video!!! NOT the click-bait that I was expecting; a pleasant surprise!!)🙂
I did exactly the same. Saw the thumbnail and wondered what horrible anti shark nonsense is going to be in this video. So that was a nice relief watching it
I do wish they would change the thumbnail, though
I have converted mollies to full saltwater many times so their definitely are fresh water fish that can switch over. In fact many use mollies as canary fish in a saltwater quarantine to watch for signs of ich or other diseases on new arrivals
The Ocean is salty from the tears of misunderstood sharks that just want to cuddle
I've always had an interest in bullshark I thought that salt water and freshwater bullshark were separate species and I always realize that the fresh water counterpart are alot smaller. The truth was that they're just offsprings afterall
The video never got back to what the shark gave up lol, and it called whales fish🥴
We found a bullshark in a river here in South carolina which was several miles from the ocean
Lets go swimming.
In australia we find bullsharks 1800miles from the sea
Funny story about being afraid of sharks as a kid. Around 1984 I was a 5 year old living in Central Florida. Right around the time of Jaws mania. That was where I had got all my info of sharks. One day while swimming with my family at the beach I saw the unthinkable. A dorsal fin maybe 50 yards away. Being a 5 year old fresh from the experience of Jaws I did the only rational thing I could think of. I took off running out of the water screaming SHARK, SHARK. And to my surprise most people followed me out. Only then did everyone realize it was just a pod of dolphins. It was at that time I felt my mother's hand grasp my arm as she lead me to the vehicle. Apparently it caused a large scene and she was none to happy. So that was the end of the Beach for me that day haha
Better safe than sorry
Mans coffee machine sound like a microwave 😂
Seals and salmon are known to spend time in fresh water to rid themselves of parasites such as lice, which quickly detach themselves from the host in fresh water. I’ve witnessed this myself. Maybe this explains why some marine species are seen in fresh water environments. I have seen seals in Loch Ness ,Scotland- maybe this accounts for some of the ‘Nessie’ sightings! 🤣🏴
This is a common practice in the aquarium trade. Salt water fish are often given a fresh water 'dip' to eliminate parasites from being introduced into reef aquariums.
Sea lice will all migrate to the inside of the mouth when a salmon enters fresh water
the octopus one was only in ohio ☠️🙏
i was snorkeling in the intracoastal in Florida and a 12 ft bull shark swam right past me. i blessed the shark with a shart
Bull sharks can turn up in all fresh water connected to the sea, here in Brisbane there are bull sharks in Carbrook golf course ponds, they got stuck there during floods.
More marine life could be moving into freshwater to escape certain threats in the ocean such as caution of ships,or more frighteningly pollution in the ocean like the islands of garbage.
Or Megaladon
Love the vids. The freshwater black Molly can live in a saltwater tank . Some goldfish too I believe . The black mollys are for sure 👍👍. So interesting .
Mollies are multiple closely related species. Some are brackish, some true saltwater. They have been bred back and forth to get characteristics into different species. The original black Mollies were from Mexico or Yucatan from a population which had black spotting and line bred for total black. These were fresh water, but still have the genetics for brackish water. Then they wanted the sail fin which occurs in the brackish and fresh water species (you can catch them in the mangroves in the keys).
The point is that how well any specific black molly does in true salt water depends on the genetic line it's from.
I was a young one when Jaws hit the screen. I might have been too young to see it but being a boy and having a crazy fascination with horror films and stories, I felt invincible! I saw the movie on the big screen with a special audio system they had back then.
2+ hours later I walked home with my friends not knowing my life was about to change. From the time I got home and for months after, I was convinced that a shark was going to come and bite my ass off every time I sat on the throne to take a dump.
Have a good laugh. I do now..
Maybe dolphins know over time they will adapt to fresh water so they are trying to speed up the process lol
I like your intro.
So relaxing
He never came back around to tell us about the bill sharks weakness
I used to think sharks swam in the carpet under my bed 😭😭😭
I love the Jaws video game hearts around 5 minutes, nice video!
the osmosis i learned about said the lower salt level sucked salt from the saltier solution until it equalised just like it does in hydroponics
lenny ? is that you , man ?
In the game called Maneater we play as a bullshark since there are multiple areas in the game both fresh and saltwater!
The sip in the intro gives me a sense of grossness everytime
"Never Give Water to a Shark"
also sharks, who literally live in goddamn water:
Even tho they’re essentially harmless on land, sharks become a thousand times scarier looking with those black hole demon eyes. Omg
Wow amazing 😍😍 beautiful 😍❤️ very nice 🙂
Now i understand why sharks are always angry at everything.
In Australia the shark responsible for most attacks is called a bull shark. A shark that is just as happy in fresh water as it is in salt water. Rivers can be dangerous.
Some saltwater aquarium keepers will dip new fish in freshwater. The freshwater will pop any external parasites before it does any harm to the fish. This helps prevent introducing parasites to the aquarium and keeps everything more healthy.
please add more funny cartoons, its more fun to watch your videos with it
Guess i gotta give my shark dairy queen.
That's an interessting topic
I just came here for "see you later!"🤣🤣😂
Lake Nicaragua Titicaca! Are you threathening me!? 🤣🤣🤣
It doesn't matter what type you shark you want to talk about. They are all feeling the heat.
I used to be scared of tall buckets because I think there's electric power in there but now it's been 8 years since I was a kid so now I think the toilet has cobras inside
5:50 Hey a shout out to the Indian River Lagoon! I used to live close by over in Stuart. A couple times for field trips we'd go to the lagoon and I saw a couple skates and a dolphin while we were on a boat.
Was the dolphin doing ok? 😔
Wasn't a Bull Shark found or caught in the Miss River up north in Minnesota or in St Louis a few years back?
Ok so this is just a theory of mine. I'm an aquarium hobbiest (saltwater). There are parasites that marine animals get and some fish are just prone to certain parasites. Take saltwater ick for example....when fish in my tank get ick I give them a freshwater bath / dip. 3-5min depending on the fish. Which while they expand the parasites are expelled out of their gills.
So my opinion is that fish know this too.
Also, increased water temperature to 82-84 degrees helps kill the juvenile ick. Ocean water is colder than river water, so with these 2 things could be a factor as to why sharks swim up into freshwater.
i saw this thumbnail and i said “WATOP FOUND KING SHARK FINALLY”!!🤣
The most fearfull marine predator.... Nope, those are killer whales.
In the fish trade you can dip freshwater fish in saltwater and vice versa. It’s a great way to kill bacteria and such.
All I know is that, having been a fish guy (tropical/freshwater fishes) for some 55+ years, many a freshwater fish have been saved using salt water treatments for multiple ailments over the years..... when I get new fish in from unfamiliar sources, the first thing that happens is they go into a saltwater bath prior to going in their isolation tanks prior to going into the community tanks.... I have tanks that have not been deep cleaned or had water changes in over 10 years..... as crystal clear and healthy as can be..... very, very rarely do I lose fish to any sicknesses..... they just die from old age... and THOSE get fed to my snappin turtle....
The octopus one is really funny😂😂😂😂😂😂😂😂😂😂😂
I never knew that, this video is
very educational.
All fresh water in NZ except trout , travel as fry from the ocean , into esturys to adjust and find their water of birth .
Salmon were introduced and only in one rive that I know of , possibly pike and koi - now a pest - otherwise it's long and short fin eels , and 13 species of Galaxid and other endemic native species , many of which are capable of climbing vertical surfaces if damp , or going cross country for a few hours .
Talk about dehydration while being in water! 🤣
You should do a video on Maleo Birds. They're pretty interesting. I won't go into detail, I'll let you do the talking. 😁
So if you ever get attacked by a Great White shark give it a drink of water.
I like this dudes voice
That shark looks like he is going to say fish are friends and not for food
When people in the saltwater fish hobby get corals and fish, it is a well known practice to dip fish and corals for well OVER 30 seconds in fresh water to rid them of parisites.
I was waiting for the bullshark answer but it never mentioned again
Yea man same that was like the only thing I wanted to know
We have bull sharks in the fresh water Swan River here in Perth, Western Australia.
The Ocean is so scary that Dolphin chose a sweet end
amazing creature
