Reminds me of a picture I saw recently, comparing the outline of a paddling surfer, a turtle, and a sea lion. All quite similar This is why most `shark attacks' are just one bite and then they leave. "Eww, that's not what I ordered." [quietly swims away]
There is some truth to it mostly comes down to the shark not *used* to humans and let's be fair out in the ocean they rarely if ever come in contact with humans. It's the same with many predators once they get a taste for it things quickly change and you all of the sudden have a manhunter(common with polar bears and tigers).
At least with great whites the theory that surfers and seals look alike seals has been challenged. Great whites have incredibly good eyesight (even by shark standards) and can distinguish between a person and a seal. That is why most bites on humans are exploratory instead of an attack that involves dragging prey under the water while thrashing. They give up after a bite because humans taste badly and aren't nutrient rich enough to be worth a full attack. Great whites are also extremely risk avoidant and will stop attacking if the prey fights back (seals can swarm juveniles) and they would much rather wait for their prey to bleed out instead of committing to another bite.
Attacks aren't always hunger driven either. Sometimes it's about territory, and humans are continually having greater and greater impacts on shark territory. Only natural that eventually a few of them get moments when they'd like to take a bite out of us.
Was down there a few months ago. The water temps in the Keys were SO hot . Not warm , hot. I did see Manatee, thankfully, lots of lobster, but only one shark . I wondered how the fish were surviving in that water
good video because, it gives the answer quick enough and direct, one can't always expect a viewer to have enough time to watch all the way until the end of a long video
Ive had 2 sharks try to attack me unprovoked in the keys. Ive also had a very large hammerhead knock into my kayak several times near the 7 mile bridge. A shark will eat you if it wants to. Always be aware of the dangers while in the ocean. It is NOT safe to be in the water, but can be enjoyed if you pay attention to whats around you.
Jasmin is such a lowkey sleeper hit of a host. Super appealing how she nudges Dr. Simonitis to open up without being too invasive--a wonderful interviewer.
I feel like the throwaway comment that you shouldn't be worried about getting attacked by a shark is a bit too dismissive of the actual danger. Yes, shark attacks are very rare, yet a the video itself addresses the research of shark repellents and how it's used to make human shark interaction less dangerous. That wouldn't be something we need if there was no danger. After all, we're not actively researching cow repellent either (though we might should as more people die to cow attacks than to shark attacks). So, I wished that the answer here wouldn't have been a flat out "No" but a bit more detailed even if it isn't the main point of the video.
You make a good point. Perhaps we should interpret the question as: “Is the probability of getting attacked by a shark while doing normal tourist activities at a beach high enough to worry about?” Phrased like that it makes more sense. Just like the chance of your plane crashing is always non-zero, but low enough to be negligible.
@@HaloHighlightz when you consider how many people work with cattle on a daily basis, how many people encounter cattle without knowing how to act around them, the average size of cattle herds, and the surprisingly low number of fatal shark attacks, it makes sense.

I'm always happy to see research that will help the environment, sharks, and humans live together into the future, I can't help but see significant flaws in this study. Of all the shark species to use, Sphyrna tiburon does not seem like a good choice as they are unlike any other known shark with their omnivorous diet. 62% of their diet, by mass, is sea grass. As such, it's pretty much guaranteed that olfactory cues and responses in this species will differ dramatically compared to the very predatory Carcharhinus limbatus. Perhaps the less predatory shark can be discouraged via cuttlefish ink more so than a species that doesn't eat mostly plants? And what effect does cuttlefish ink have on driving away other animals we don't want to disturb, like parrotfish or manta rays? This study, or at least what was presented to us, provides no evidence for how sharks that actually attack people would be affected and no evidence on how threatened harmless species, including close relatives like mantas will be affected. These two points may seem to conflict, but that certainly isn't the case. It certainly possible that bull, requiem, or white sharks would not be fazed while mantas could be repelled. There is a lot more work that needs to be done to see if this is useful information.
We can not smell anything until the molecules reach our noses so what we smell is right under our noses, we can then infer direction and distance together with other senses and if we’re upwind from the smoke we won’t smell it at all
Ok peps in order to smell anything no matter what creature you are the molecules must enter your nose. Those molecules might have come from far away, miles even, but when we smell them we are smelling the molecules in our noses not the molecules miles away
Human female: ooooh look at them they are sooo cute Shark: oh no not again two of those ugly 2 leged landcrawlers. i can sense their stinky synthetic smell from miles away. i dont even want to eat them when they come into my territory. whenever i can i just take revenge for every of my brother and sisters, that their ancestors killed ruthlessy in the past.
This experiment would be a lot more meaningful if it was double blind with multiple targets. Every experiment should involve a logician, an experimentation expert and a domain expert.
It probably was. But this is a video illustrating what was found. It is not the actual study itself. I doubt you want to watch a 1000 hours of little sharks circling a piece of plastic.
That's a big misleading least to say, I'm sure it depends on the shark but let me tell you if you're a human and you jump into the ocean to swim alongside white sharks and cuddle with them, you're food. Period.
Very disappointing video. Your scientist didn't even consider the hunger factor! We see more and more attacks on humans because they are struggling finding food.
And we are coming in contact with them more as sharks are coming in towards the shores more. We believe this is due to the ocean temperatures changing and fish coming closer to shore which in turn forces the sharks to come close since they're chasing their food.
The Internet is not natural, I didn't read this. You should probably stay off of the Internet then. Also, purple. People who don't know the difference are unnatural, and I didn't read this comment because of this. 🙄
The way sharks swim is so elegant .

Wearing a wetsuit makes us appear to be "seal-like" but then, we don’t taste good

So cool to see ongoing research happening (also the little bonnetheads are so cute 🥰)
Badass behavioral ecology. LOVE this!

The ocean Temps in some areas were equal to a hot tub last summer.
But climate change is just a liberal commie myth to charge more in taxes.
Yeah this past summer there was a record set in the keys for the hottest water temp. I wana say it was like 100 degrees.
Fish heads, fish heads. Rory poly fish heads 6:31

Most shark attacks on humans happen in Florida waters. If I ever retire, it will not be to Florida.

Wow never knew anything about shark noses before, so interesting that they aren’t connected to their mouths and have passive flow paths.
Our purple hair colors match! Yusss!

I agree with what you said wholeheartedly. But I got stuck on the more ppl die by cows than sharks, really??
@@HaloHighlightz I got stuck on "might should"; is that a common phrase in your neck of the woods?

Loved this video! Sharks are so cool. Learning about biology is fascinating
Fun fact: Julia Child created an early shark repellant during her OSS days. it's often referred to as her first "recipe"!
Do tell!
The nose knows!
this was a really cool look at sharks!
"should you be worried about getting attacked by a shark while going to the beach?" NOOOOOOO .
THANK YOU! ❤
Here's a thought, when someone breaks wind, you actually get their matter in your nose, which is how we recognise it. Say what for a mask...?
i ♥️ sharks
turkey vultures easily can smell more than a mile away. lets have a documentary about them
I saw that jar and i just knew it had to be ink. Thats so funny, the thought of milking a cuttlefish 😂
These gta 6 graphics are absolutely amazing
Love the sharksand the purple hair!!!

We can smell smoke from miles away.

Would have loved to hear how the water gets pushed in (is it the head shakes?) instead of hearing the anatomy twice.
My hobby is making and collecting stinky chemicals. Even people can smell a single small drop of something from a mile away.
I can smell bullshit from 100s of miles away😂😊
You would love to capture the scents I produce after eating tofu
And it doesn't matter if people aren't interested in the smell.
SBDs? 😂 @@Dumbledore6969x
So we're just making shit up now?

I'm not sure ww2 sailor veterans would agree about sharks ignoring humans. BTW, very cute researchers.
I love nature, but y'all might want to hire a writer. 😢
Leave it to Disney to perpetuate a myth. Remember the sharks from Nemo? That stuff is so ingrained in our dna meanwhile...
Remember “Jaws” (1975)? Sharks were not seen as a particular threat to people before that film.
