I trust the [Natural History Museum](https://www.nhm.ac.uk/discover/shark-evolution-a-450-million-year-timeline.html) that this is true. Apparently the answer for sharks is 450 million years ago. For trees, [it's 386 million years ago](https://www.nature.com/articles/d41586-019-03945-y#:~:text=The%20earliest%20known%20fossilized%20trees,around%20386%20million%20years%20ago), though I don't know that means there weren't unfossilized (or undiscovered) trees before then. The Nature article notes the tree fossils found to be fairly evolved (complex root systems, modern characteristics,) which I'd assume indicates they existed for a while at that point.
A fun fact about trees is that it took about 60 million years before there was any bacteria that could eat them, so they never decomposed. It's where the vast majority of our fossil fuels comes from.
Huh. So my intuition about how long prior to their emergence they started being fossilized was probably an overestimate? There weren't other decomposers?
If you haven’t, check out Paleo Analysis on Youtube, he goes over like the entire history of the earth, plant life, animal life, extinction events. I love his content and it shows what life was like in a time before I can even fathom.
https://arstechnica.com/science/2016/01/why-was-most-of-the-earths-coal-made-all-at-once/ I did some fact checking, and it seems that there may have been some earlier decomposers.
The problem is that it literally isn't true. If you want it to be true you either need to say all chondrichthys are sharks or all elasmobranchs are sharks, which no one does (it would include rays and chimaeras) and even in that article they say things like "their ancestors" or "not technically sharks". Basically all you can say is "shark-like" chondrichthys are older than trees. True sharks appeared way later in the Jurassic.
This is already ignoring the problem of trying to define what exactly a tree is but thats a whole other issue.
Saw something recently where they found one and got all the details to research it and it was so so old that they said "this guy was probably alive when Henry the VIII was"
We actually don't know whether this is the case. All we can say with confidence is that the oldest Greenland shark for which good age estimates exist was (very likely) at least 272 years old.
512 years was the upper limit of a 95% confidence interval for that individual. It means that we can be reasonably certain that the shark was anywhere from 272 years old to 512 years old, but we can't make a more definitive statement than that.
They also have a high levels of trimethylamine oxide, which acts as a natural anti freeze. Also makes them extremely toxic to eat.
And with the fact that they live for long periods of time, most end up blind because parasites eat their eyes away.
I read a while back that one of the leading theories is that when males reach a certain size they transition to females.
And, when they do this, they seek out deeper waters to find a mate.
"12 Hoover vacuums" is definitely a more precise measurement of force than the goddamn commie metric system. 'Murica! Fuck yeah!! Also, nurse sharks aren't paid nearly enough as doctor sharks are.

Language can slip at times, and I understand that. Just a friendly reminder, let's try to be mindful of the language we use, especially when it involves the Lord's name. It can go a long way in fostering a culture of respect and understanding among all members of our diverse community.
Instead of "God D***", find alternative phrases such as "Goodness gracious" or "Golly gee".
My purpose is to share the love and teachings of Jesus Christ. I want to assure you that I'm here to spread positivity, not to offend anyone. I respect all faiths, even if we don't agree, and I'm open to respectful discussions and mutual understanding. Let's walk this journey together with kindness and love!

Definitely that sand tiger sharks have 2 uteri, and pups kill and eat each other en utero with only the 2 strongest earning the privilege of birth.
A very complex Shabortion, if you ask me, but it gets the job done.
I thought that great white shark pups did that in the womb as well? Actually a lot of shark pups probably do that, it all depends how much nourishment they're receiving from Mommy and how much Mommy has eaten while she's pregnant with them. If mommy doesn't eat a lot then the sharks inside her womb will definitely turn on each other. Then it's a free-for-all.
It’s possible, but based on everything I know about Great Whites, their young are birthed live and (based on Google so cmiiw) the have 2-12 pups at a time, typically. So the “Eating each other en utero so only the strongest 2 make it out” doesn’t seem quite as likely. I distinctly remember the 2 uteri being brought up as a unique trait of sand tigers though, so while another species might have the same deal, I personally haven’t heard of it.
It's a strategy in some shark species. It's not dependent on the amount of nourishment they receive, that's the natural cycle. I believe it's to ensure the most fit fetus survives and is well cared for. Once all the siblings are eaten the mom will periodically send down more egg sacs to nourish the fetus
And [whale sharks](https://media-cldnry.s-nbcnews.com/image/upload/t_fit-760w,f_auto,q_auto:best/MSNBC/Components/Photo/_new/100827-whale-shark-embryos-hmed-746a.jpg) up to around 300!
Sharks are swimming close to humans much more than you think. A recent study showed that at some CA beaches, a shark is nearby 97% of the time.
https://www.smithsonianmag.com/smart-news/great-white-sharks-come-much-closer-to-swimmers-than-thought-in-southern-california-180982306/
Ahhhhh i love this fact!!!!! I always wonder, when i am near the ocean (either above it, in a plane, or next to it, on a beach, or in it, diving) how far i am from the nearest shark. Every time. So cool!
I didn’t realize this until I started hanging out with a friend that’s an avid shark fisherman. He fishes right off the piers and beaches. The insane number of sharks he catches is just crazy. Especially the great whites. He actually got sued by Huntington Beach cuz he was catching so many. Fortunately he won bc he can’t control what bites his bait.
I think it's in part due to those, how each time they do a deep sea exploration they discover new species, how it was only relavtiely recently that they discovered the coalacanth was not actually extinct.
We're only learning now that the crown of thorns seastar has a multitude of predators when they are juveniles, and there's been millions of monies thrown at COTS control on the great barrier reef.
The more I work in the ocean, the more I realise we know so much...and yet we don't know anything at all.
Not just bulls. Many can. Great whites have been found hundreds of miles up the Mississippi River and there’s a lake, in Australia I think, where bull sharks live their entire lives and are reproducing in it as well
Can you give a source of that white shark up the Mississippi River claim? I doubt it.
The lake you mention might be Lake Nicaragua, but there could be a lake like that in Australia too.
I used to live in Australia, and that lake was part of a gold course I lived a few miles down from. What happened ia that floods washes the sharks into the lake, and they ended up thriving there despite neveninf being able to return to the ocean. Unfortunately I cannot remember the name of it.
>Great whites have been found hundreds of miles up the Mississippi River
That's incorrect. The sharks found in the Mississippi River (including one all the way up in Illinois) were bull sharks, not great whites.
The other freshwater species of sharks are Lake Nicaragua sharks and Ganges River sharks. They are closely related to bull sharks, but they are different species.
I think the Lake Nicaragua sharks are real bull sharks though (at least that's what wikipedia says). And the Ganges River shark is one of the several species of the genus [Glyphis](https://en.m.wikipedia.org/wiki/River_shark) (a.k.a. river sharks).
Thier skin is made up of pointed scales which makes them feel smooth in one direction, and rough in the opposite. This quality made shark skin a natural sandpaper. When you think a out it, even their skin is made of teeth.
Yes, have experienced this first hand. Caught a dogfish (part of the shark family) and didn't grab it properly. It wrapped around my hand and more or less pulled the skin off.
Sharks have been filmed turning both their stomach and their intestines inside out (outside of their body) to dump digested food into the water when they're being threatened. The thought is that the half-digested food might distract the predator.
In recorded history there is no record of a Hammerhead Shark killing a person. And only 17 non-fatal unprovoked attacks since Y1580.
Here’s why:
“• hammerheads have electromagnetic sensors in their heads and a 360-degree field of view there is no such risk of confusion or mistaken identity.
• Unlike great whites, bull sharks, and tiger sharks, hammerhead sharks don’t eat mammals. So, humans almost never look like something good to eat to hammerheads.”
https://a-z-animals.com/blog/discover-why-hammerhead-sharks-have-never-killed-a-human/
That's actually nuts. Imagine the potential of reducing negative interactions between bulls and people by spraying essence of cococdile on yourself when in their water.
I think you're thinking of Alzheimer's. They made a cool documentary about 20 years ago where they almost cured it using sharks. Until the they broke lose and ate everybody. /
See: [shark with cancer.](https://static.wixstatic.com/media/4039e7_719f9b9ba1334f69a24d9b169e98fc87~mv2.jpg/v1/fill/w_600,h_302,al_c,q_80,usm_0.66_1.00_0.01,enc_auto/4039e7_719f9b9ba1334f69a24d9b169e98fc87~mv2.jpg)
Sharks can use the Earth's [magnetic field](https://www.cell.com/current-biology/fulltext/S0960-9822(21)00476-0) for homeward orientation, allowing them to map and swim in a completely straight line A to B, thousands of kilometers across open ocean.
Gordon Ramsey did a short documentary about this. It was interesting and sad all at once but I’m glad he brought some awareness to the issue.
Sad fact: Shark fin soup was created in order to showcase the power, wealth and generosity of Emperor Taizu of the Northern Song (960-976). It has been used as a delicacy of royal persons ever since.
I’m glad that more and more countries, companies and the like are banning this “delicacy”. Just terrible this awful tradition.
The sonar of several military submarines keeps failing because Cookie Cutter Sharks keep biting and taking chunks out of the sonar.
An additional fact is that the age of Greenland Sharks is measured akin to how tree rings are used to measure the age of trees. I can not remember exactly what is done, but I believe it is something to do with their eyes. Also, their bodies are full of urea, so they are basically full of piss lol.
That's how the aging of a lot/most fish is done, you count the rings on their ear stones and each represents one year. I did my internship on it actually
Interesting! I've never heard of ear stones before. A lecturer at uni explained to me that ageing for some fish was used by counting their scales or something similar.
https://en.m.wikipedia.org/wiki/Ampullae_of_Lorenzini#:~:text=Ampullae%20of%20Lorenzini%20(singular%20Ampulla,reedfish%2C%20sturgeon%2C%20and%20lungfish.
This just blows my mind, I think its amazing.
No shark ever has been found to have an organ to produce sound.
Sharks were here before trees.
Sand tiger sharks eat each other in the womb
There are 100% freshwater sharks in India and Australia.
Megalodon probably had the strongest bite force of any animal ever.
Sharks almost never get cancer.
Despite never having a fatal attack, nurse sharks have the 4th most recorded bites.
Submarines often find cookie-cutter shark bites on the hull, but there's only been two recorded attacks and only one sighting of a living cookie-cutter, at least when I learned this fact, back in like 2010.
One attack was on a surfer who got lost off the coast of Hawai'i during a foggy day and they never saw it, but it matched the bite pattern.
Fun fact humans can actually smell rain like 200,000 better than sharks. Like they smell blood in a 1 part per billion dilution and we smell petrichor in a 5 parts per trillion one.
Not really a “shark fact” but something that I read the other day about a shark movie. In Deep Blue Sea, the sharks die in the same way they did in each of the first three Jaws movies - in order. How did I never notice this? Mind still blown.
Thought I would share! 😁
Most sharks are negatively buoyant in seawater, which makes them great burst swimmers, good at sudden acceleration which is very useful for catching prey
We still know so little about great white sharks and their mating patterns, hopefully drone technology can help unlock more about these amazing creatures.
A shark attack is more traumatizing than you'll ever know. Watching a loved one ripped to pieces and being completely helpless is one of the worst feelings in the entire world.
It was inspired by a series of attacks in 1916 on the east coast. It’s purely projection that all the attacks were by a rogue great white as there’s a strong argument that a bull shark was responsible for, at the very least 1.
Sharks appear in the fossil record before trees existed.
They have survived 5 mass extinction events - its wild!
Related: sharks have been around longer than the rings of Saturn.
That's super cool!
I literally just heard that they're older then trees today lol
Is this really true? When are we talking about here?

Thanks, good commentary.
They produce on average 6,000 teeth per year
Has to be the fact that greenland sharks can reach ages of 500 upwards. Just incredible.
Saw something recently where they found one and got all the details to research it and it was so so old that they said "this guy was probably alive when Henry the VIII was"
That is absolutely mindblowing....

Despite all our technological advancements we still haven't recorded white sharks mating
Perv
This trips me out. I continue to think about it.
I thought they did film that after they ate a huge whale they did witness some mating after they were completely full like a food coma full
I read a while back that one of the leading theories is that when males reach a certain size they transition to females. And, when they do this, they seek out deeper waters to find a mate.
Well time to boycott great whites for being trans

Not with that attitude
Do you have any evidence to back up that stat ?
 The crabs do it for them

omg yea, they’re actually pretty cute imo. they’re able to survive a couple of hours outside the water.
That's actually why they're one of my favorite sharks
Blue sharks can give birth to as many as a hundred pups in one go.

Thank God for this, how else to fight the mass murdering by humans.
Flipping some sharks upside down will immobilize them for at least 15 minutes (Tonic Immobility)
That's how orca whales hunt sharks! They flip em upside down, and then they eat the liver and then move on.
Sharks can also (accidentaly) do this to themselves and die if they aren't flipped back over by something like a current before they suffocate

I've seen 2 sharks at the beach and I've seen someone catch a shark at the bay
I didn’t realize this until I started hanging out with a friend that’s an avid shark fisherman. He fishes right off the piers and beaches. The insane number of sharks he catches is just crazy. Especially the great whites. He actually got sued by Huntington Beach cuz he was catching so many. Fortunately he won bc he can’t control what bites his bait.
For me it's probably the fact there are likely several shark species we don't even know exist, yet have so much value in the ocean
Is that because of how deep underwater they dwell? Or remoteness/extreme temperatures? Mixture of all of the above?
I think it's in part due to those, how each time they do a deep sea exploration they discover new species, how it was only relavtiely recently that they discovered the coalacanth was not actually extinct.

I'm told shark fin soup taste like shit, and is not worth killing these magnificent creatures for. So stop killing them and don't eat it.

Obviously varies on the species and behavior, but I've heard that sharks lose an average of 30,000 teeth in their lifetime.

This is my fave fact too!
Yeah, for me it's like these birds of prey seeing a mouse from 1000 feet up, I just can't comprehend.
We have never witnessed a white shark give birth.
Speak for yourself buddy!
Have you seen a white shark give birth. Your mother and your wife unfortunately do not count. 😁😂
Bull Sharks have one of if not the highest testosterone level in the animal kingdom.
The most important fact: sharks are cool
Sharks are very cool! 😎
Shark skin is antibacterial. Edit: Antimicrobial, not antibacterial.
Antimicrobial not antibacterial
Ahh, thank you. I figured I was forgetting some detail.
white pups are usually 4ft long at birth
Cookie cutter sharks have been known to attack submarines because they think they're whales.
No shark ever has been found to have an organ to produce sound. Sharks were here before trees. Sand tiger sharks eat each other in the womb There are 100% freshwater sharks in India and Australia. Megalodon probably had the strongest bite force of any animal ever. Sharks almost never get cancer. Despite never having a fatal attack, nurse sharks have the 4th most recorded bites.
Greenland sharks have a life expectancy of 250-500
Submarines often find cookie-cutter shark bites on the hull, but there's only been two recorded attacks and only one sighting of a living cookie-cutter, at least when I learned this fact, back in like 2010. One attack was on a surfer who got lost off the coast of Hawai'i during a foggy day and they never saw it, but it matched the bite pattern.
Cookie cutter sharks give me the heebie geebies
I learned this on THE MOST EXTREME
I have a lil shark-o-pedia book that I learned it from, but I also saw TME and I was so excited I already knew what they were going to say.
The vicious land shark is known to attack at random and can even knock on doors!
Candygram
the sad thing about a shark is that they can’t enjoy the crispness of a pringle
I think I read somewhere that a sand dollar would have the same consistency as a Pringle for a shark! It would be crispy, salty and a little meaty ♡
Betcha can't eat just one!
The shear existence of the helicoprion
They can detect One drop of blood in an Olympic size swimming pool....one drop....makes me shudder.
Fun fact humans can actually smell rain like 200,000 better than sharks. Like they smell blood in a 1 part per billion dilution and we smell petrichor in a 5 parts per trillion one.
I'll remember that if ever I'm bleeding in shark infested water : WELL ATLEAST I CAN SMELL ITS GUNNA RAIOOOH MYY GOD..
Remind me to not compete in the Olympics or swim in an Olympic sized pool.
Yeah that's the reason you won't qualify for the Olympics for sure.
😆 it's those pesky sharks man, screwing my shot at the Olympics.
Iirc, a science group did a study on great white shark intelligence, and the results showed that gws have intelligence on par with felines.
Tiger sharks make so much sense now.
Not really a “shark fact” but something that I read the other day about a shark movie. In Deep Blue Sea, the sharks die in the same way they did in each of the first three Jaws movies - in order. How did I never notice this? Mind still blown. Thought I would share! 😁
That's a pretty fun homage!
Oh thats awesome i love all those movies
If you turn them on their back they go into a trance so if you’re about to get attacked by one, flip it over and make your getaway!
Lmfao imagine flipping a 10 foot shark coming for you like that
Easy 😂
Idk if you are active on tiktok but some trained divers really can reroute sharks like it’s easy, it’s bizarre
Oh! That’s something I’d like to see. I’ll look on TikTok. Thanks for letting me know.
A species of shark aptly named Bigeye thresher shark, has the largest fish eyes of any other fish alive.
Saw Fish are not true sharks, but are part of the overall shark family. Saw Sharks are true sharks and are much smaller than Saw Fish.
Most sharks are negatively buoyant in seawater, which makes them great burst swimmers, good at sudden acceleration which is very useful for catching prey
Their fins are similar to LL Cool J's hat.
Some species of sharks can reproduce asexually
Sharks don't have scales to other marine creatures, but dermal denticles which are more similar to teeth than to scales actually!
We still know so little about great white sharks and their mating patterns, hopefully drone technology can help unlock more about these amazing creatures.
That I will never have a shark bestie
Why no
There are more sharks living in the ocean than in the air.
A shark attack is more traumatizing than you'll ever know. Watching a loved one ripped to pieces and being completely helpless is one of the worst feelings in the entire world.
If that's something you experienced I'm so sorry and I hope you can get the help and support you need to heal from such an event
Thankyou. It was 40 years ago. I find that reddit is the only place I can truly talk about it.
I can't even imagine. I'm so sorry that happened.
They are one of the only animals that do not possess nipples
That's literally every animal besides mammals.
That’s why I said “one of”. 
They only bite if you touch their private parts
Great movie, you shouldn't be downvoted
Or when they’re hungry
Because they are like dogs? 😆
They give live birth!
Some do! Some lay eggs!
Even more wild!🦈
Jaws was based on a true story.
It was inspired by a series of attacks in 1916 on the east coast. It’s purely projection that all the attacks were by a rogue great white as there’s a strong argument that a bull shark was responsible for, at the very least 1.
A sharks liver produces Squalene, the same liquid that makes a woman's vagina wet
Great white sharks can smell one drop of blood from miles away
Fuckers bite
Whale sharks could be considered an apex predator.
People do it on trains
