Tunas hunt in relatively deep water, which have low to little light. To feed, they usually dash at the slight shine reflected off its prey’s body, without much cognitive processing (like a reflex). In this case, I’d think that it mistook the photographers flash as prey and had its instincts kick in, causing it to dash towards the glass panel. This is why many aquariums have a strict regulation against flash photography. There might have been other reasons but I would think this would be the most likely scenario. Update: didn’t think this would garner so much attention since I typed this at 3AM on a random day 😂 guys i’m not a marine biologist, and it’s just a speculation so everyone is open to their own thoughts oki 👍🏼😊 Up-update: If you are wondering how I arrived at my thought, it’s from my existing knowledge. Though I said I ain’t a marine biologist. I did grow up with plenty of marine life and knowledge about marine life, because my dad is a marine life expert with 45 years of experience ❤️
They use reflective glass, camera flash cannot go beyond the glass. Not to mention this is one of the best aquariums in the world, they must have thought about this. The tuna was just thinking that it was just swimming in the ocean, not knowing there was a glass.
@@cabbage_cat the fish was definitely racing towards the flash because it hit the exact spot where the flash shown on the glass moments earlier. Poor thing.
@@cabbage_cat Reflective glass doesn't mean it 100% reflects, most stuff are between 95%-99%. Flash can still go through depending on angle and where the fish was(they have shit close sight). Fish eyes' refractive index is 1.67, what human eye perceive as flash block may not be so in a fish's eye.
Since this video is being pushed, it’s a good time to mention that this fish is not the only one dying in this aquarium. Whale sharks are know to live 80-130 years in nature, while the longest one has survived in captivity was 26 years. I find this disturbing. Supposedly a whale shark doesn’t even sexually mature until 30, so while this aquarium may have the record for longest living captive whale shark, it is by no means impressive.
I agree with you but just wanted to point out that this video is about the tuna that swam so fast it killed itself upon impact with the glass, not the whale shark.
@@TierraD2021 That's nice, but my specific comment happens to be about the captive whale sharks. A lot of the japanese and korean comments I've translated seem to focus on them wanting to visit the aquarium, so I thought a comment like this was needed. Edit: Sorry if the tone seems rude, I didn’t mean it to come across aggressively :P
Impressive fact : tuna muscles are able to generate such strong bursts of energy that they can literally cook themselves from the generated body heat alone.
Many large sea animals (such as the whale sharks in the video) can only eat huge schools of tiny fish and shrimps because their teeth and digestive system prevents them from eating larger ones. Their size also made the lifestyle of chasing around prey and eating them horribly inefficient. The largest predatory animals are always smaller than a lot of the non-predatory ones.
It was probably attracted to all the camera flashes. I’m sure there was a sign saying “no flash”. It’s wasn’t having a moment of clarity and trying to escape, it’s a fish… Which was most likely born in a tank and hasn’t ever known anything else…
I was actually wondering if it was wild-caught. I know that wild freshwater fish put in a hobbyists tank will initially swim into the glass bc they're not used to glass or being stuck in a box.
Yeah same. I thought it had over exerted itself and popped its internal organs. It’s probably because the sound of the other guests drowns out the sound of it bashing against the glass.
@@Ruby-wp8tn wrong, sister worked at Monterey Bay and always told us to turn off our flash because of scenarios just like this. this isn’t the first time a fish has paid for some moron’s ignorance.
@@Ruby-wp8tn We know that As someone explained in another comment, tuna use the reflection off the scales of their prey to locate them The flash of someone's phone camera confused this tuna and caused it to swim into the glass at hunting speed
@@Ruby-wp8tn It may be less than normal glass, but it is enough to potentially confuse the fish, as seen here That's why most aquariums have signs posted
Not only that but flash photos taken in these conditions come out awful anyway. You'd see the people in front of the glass or at least the backs of their heads and almost nothing inside the tank would even appear in the photo because of the glass reflecting the light of the flash back towards the room. The only way to get a good photo here would be to increase the lens exposure and no flash. Only then would you be able to take a photo of the fish in the aquarium.
For those who couldn't find it. It's at 0:28 top right. Poor fish thought it's an ocean so swam at full speed till he collides with the glass. Dies instantly.
Fish don’t have cognitive thinking. And that’s a tuna. It dashes at the slight hint of reflection. Someone probably had flash photography and it dashed straight into the glass thinking it was prey.
The acceleration of that tuna is fucking incredible, he just covered half of the aquarium in 1 second. Sadge that these magnificent creatures (including all the animals of the aquarium) live in these conditions
Other aquariums use a bubble curtain in front of the glass to let the fish knows not to crash into it. It is a simple and inexpensive solution. I am surprised they don't have it installed. It could have been a camera flash that triggers the fish, but the aquarium is lacking in fish protection.
Well someone said tuna can swim so fast they can cook themselves from the generated body heat alone maybe it bursting open was from the heat. I think that's what we saw happened but I could be wrong
Every adult has walked into a glass or mesh-screen door at maybe a couple of miles per hour. Now, imagine the speed at which that fish swam into the aquarium's dense glass-wall. That is horrific.
I did that. Went right through a glass sliding door. Needed 21 stitches in my arm and 38 in my thigh. Came within 6 millimetres of severing my Femoral artery.
@@min-yw8es hey, thanks for asking! Yup! Aside from two massive scars, I'm fine! It's amazing what the human body can recover from as long as you don't hit any major parts!
It's also interesting to watch the reaction of animals immediately on the tuna's impact. The few predator species snap to going to the impact, the majority prey species snap to escaping away.
But why did those same predators not go after it? It was a fresh kill--they saw it, or the immediate aftermath, yet their instincts did not compel them to tear it apart. They are conditioned to their daily handouts from the aquarium, maybe?
@@txjack1787 Maybe they weren't hungry. Preds don't usually kill just to kill. If they are being well fed, they'd have no reason to hunt the other fish. I expect this is the case so they don't have to keep replacing their large tuna and mackeral and stuff.
@@JessRansdellSmith It's a wonder they manage to feed them so effectively even in this controlled environment, like... no fights over food that gets dropped in or anything?
The fish that killed itself wasn't some run-of-the-mill fish either, it was a tuna, one of the fastest fishes in the world. In fact they're so fast they have to limit themselves to prevent the water around then from cavitating and producing shockwaves
I think it is because of the flashlights from cameras. Aquariums prohibit the use of flashlights at all, because it will shock and trigger the fish. In this case, that fish was shocked and rushed towards the glass which killed itself from the impact
Insight into what happens in the ocean? Wtf is wrong with you? There are no glass walls in the ocean?! Those aquariums are hell on earth! When I see these whale shark in a fckn tank I could cry
At that moment, the tuna became self aware and tried to escape. Also, on a serious note, it’s not the flashlight as some comments pointed out this aquarium uses refractive glasses to prevent flash light from getting in.
The poor thing... I always wonder how hard it must be for the animals to determine where the water ends and where the glass is. But damn, that fish must have been scared away by something. It was swimming so fast straight to the glass.
@まきば乳牛 They call them idiots because everyone hate those people who uses flash light in a aquarium, but I don’t understand why you call those who commented idiots. They might be wrong but you don’t have to be so rude
@@potatoeskimos A fish is a conscious being. That alone should be enough for you to understand that they are not supposed to be locked up in tanks. Research has shown that not being in their designated natural environment causes problems in their development. You and I can both agree that this isn’t how we should be treating life on our planet.
@@4hoofd non-mammal are droids. They lack emotions, are leas sentient and have simple needs. Fishes are fishes, they do what they do. I agree we shouldn’t take them of out their natural habitat, but I feel less sorry for them compared to say, a cat or a dog whose more complex than marine life.
@@potatoeskimos That's completely understandable, and honestly i agree to a certain degree. A dead cat would make me feel much sadder than a dead fish. It's hard for me to just accept that non-mammals don't experience any distress though. We have the technology to understand certain brain activity, but there's no way for us to just 100% conclude that their experience of "negative emotions" are measurable through those observations. Anyhow, animals don't belong in enclosures and hopefully that'll become a fully accepted norm.
What an Incredible shot you've got there, the aquarium in full scale and you see the crowds black silhouettes underneath. That shot is incredibly well done.
@@diyanfonseka personally i don't think there is a time either place where to say that the aquarium is a good shot, behind that shot "incredible well done" there are sentient beings wich in their nature are being capable of live over 20 years, imagine being in an aquarium where you live much more shorter for years because of stress and wanting to kill yourself.
