Sharks are NOT worms
Greenland sharks have worms in their eyes mist of the time.
Kyurem thank you, I will update my nightmares.
I dont know, the Dwarf Lanternshark looks kinda like worm with a small fin and if you stuck it on a hook you'd probably catch something. Wouldnt recommend using them in your garden though.
Who knew?
XD
Surprised that the Cookie Cutter sharks didn't make this list, being that they're named for the way they grab onto larger fish and just sort of wiggle around in a circle, cutting out "cookie shaped" chunks of flesh to eat. During the cold war, Cookie Cutter sharks often tried to eat submarines, and sometimes damaged their sonar equipment in the process. For a long time, the U.S thought that the Soviets were using some kind of new anti-sonar technology against them until they discovered it was a bunch of misguided sharks.
cain lOL that’s actually hilarious! These sharks definitely got a taste of iron hahah probably thought it was the bloodiest thing they’ve ever had due to the heavy iron taste
That's adorable and also proves that Cookie Cutter sharks aren't the brightest
@@Patchwork_Dragon They're not that adorable when you see pictures of dolphins with hundreds of round scars, up to 5 cm in diameter.
@@koffieslikkersenior i know what they can do, i just think it's funny that they mistook submarines for whales and/or dolphins.
Patchwork The Noodle it is, and they look funny too, but still... damn
“Remember when they dumped tea in the ocean?”- Greenland shark
Yea good times
"Remember when those strange creatures arrived riding longships to N. America about five hundred years back while hoping islands around our home?" -Old Greenland shark
Oh i member
this must become a meme now
Only 1500s sharks will remember
Every picture I've ever seen of a thresher shark (viewed from the side) makes it look like it's absolutely horrified that it just had a picture taken of it.
"*GASP* NO PICTURES!"
OH NO MY MAKEUP
LOL! 🤣
They must be camera-shy! 📷 🦈
He’s not very photogenic :c
It looks adorable
How fitting, that the longest living shark looks like it's made out of stone. :)
Godhelpsaveme is my favorite size of any animal
I’m glad to watch a shark video that doesn’t claim Megaladons still exist
Same, everyone should know they are extinct.
Oh yes, but they do exist. Sasquatch told me so.
Indeed! Those idiots.
I'm sorry, where is your conclusive evidence that they don't? Have you seen every square foot of the ocean all at once to make sure they aren't there?
@@DavidDatura The real idiots are the people who think they know what's in the ocean.
True shark fans didn't learn anything new, but thoroughly enjoyed the video nevertheless.
Lol! We should form a club 😂
And then he says in 2010 it was confirmed Thresher sharks whip thier prey. I've been knowing this since the 90s reading animal books in elementary.
@@chachob.9698 It's also been known for longer than 2016 that Catsharks glow. But oh well, the facts are true nonetheless, despite the timeframes being wrong.
@@Cypresssina I'm down! lol
@@yaboyjosh3023 The club that enjoys the fact that they bite 😂
It's a dumb and petty thing, but it frustrates me how often Goblin Sharks are depicted with their jaws extended forward. Yes, that is how they bite/catch prey, but most of the time, their mouth is tucked in and they look like most other Sharks. It's like depicting a missile as an explosion.
And what are missiles usually used for?
That something Guy I totally agree with you
They do the same with alot of snakes, showing their hoods fanned out and their fangs extended like that's how they sit all day.
ThatSomethingGuy it’s sort of implied that they don’t though. In my opinion I thought it was obvious
it's a pretty good strategy imo...showing the most unique and distinctive features of a species usually increases interest in the animal itself which is what it's all about and helps the animal in the long run
Nobody:
Me: **adds Wobbegong to my vocabulary**
*"actually I know loads of people who did that"*
I love sharks. We need to protect them. For as fierce as they are their numbers are getting decimated by over fishing and Shark finning. Thank you for this video ❤🦈
We love you, too.
Pelenato sends his love (my adopted tiger shark from Shark Angels) xxx
The problem is not overfishing, it’s people overpopulating
Wouldn't say they are fierce. Just animals trying to live their life, but that doesn't stop the popular media from demonizing them as bloodthirsty killers. They are actually pretty friendly.
Nah.
The beauty of sharks and the unparalleled creative force of natural selection transforming them humbles me deeply.
I've always been amazed by their diversity and resourcefulness as well.
@@annaliseoconner9266 you know it. They are magnificent animals.
Imagine how many human species there could be in 10-30 million years? :)
@@TragoudistrosMPH now that is an interesting question. I guess many but they wouldn't be a human species anymore. Maybe still Homo genus.
@@TragoudistrosMPH
evolution requires four things to work.
selection
mutation
isolation
recombination
for a seperate species to develop isolation is necessairy and seeing how globalization and migration keeps humanity from forming isolated populations, i don't see humanity spliting into many different species.
there is a strong possibillity that the sentinelese people, who are living isolated on an island under the protection of the indian government, might evolve into a seperate species, given that we keep leaving them alone for long enough. but that is just one isolated population and once they invent the ship, they too will no longer be isolated.
so unless world war 3 destroys all human technology, forcing us to only ever mate with people who live on the same land mass, i don't see humanity spliting into different species ever.
This man is always so endearing and non-threatening, we're truly blessed
I teach biology and environmental science. at a community college. I actually studied sharks in graduate school. I use your videos all the time. You should do one about different eco-friendly alternatives to burial
Those are great! I really was hoping to see cookie-cutter sharks, but I actually saw a few that were new to me instead.
Wait, sharks use cookie cutters? Huh, learn something new every day
Will you enlighten us?
@@woodfur00
Cookie cutter sharks are really cool small sharks. They have ovular mouths and actually don't usually have to kill their prey. Instead they open their mouth until it is fully circular shaped, and then bite into the side of the prey. After that they can spin their body in the water while they bite down, cutting out a near perfect circle of skin & muscle from the outside of the animal (smaller than the diameter of a can of soup).
Scientists originally found it and pieced it all together after spotting larger sharks, whales and dolphins with circular scars and wounds on their sides or fins.
Duude.
I don't know why they weren't in this video. That's awesome.
I was hoping for cookie cutters too.
waiting 150 years for the first date :P
what if they take it slow?
SciTech_387 finally, another person who isn’t judging me for being 99999999 years old and without a girlfriend

Wait, so this shark isn’t legal til age 150?
Oh no

Lame
Stephen Cook you sir may be a shark because you are lacking a funnybone.
Roosevelt Brentwood 🤦🏾♂️😱
About half the shark species described in this video, I’d never heard of before...very interesting and educational.
Honestly you guys still have one of the best youtube intro jingles of all-time in my opinion. Short, satisfying, and far from cheesy.
Great episode too. I love animals! :D
That feel when 125 years old would still be jailbait.
Imagine spending 100+ years as a child/teen
SHARKBAIT HOOO HAHAA
So, most centuries to decades old Loli's in anime now a days to justify the Loli character hitting on the teen, 20 something, 30 something human year old MC.
Even 150 years is still jailbait, since humans don't become legal as soon as they're sexually mature. Girls usually start their periods at around 11 years old, and become legal at 16 (if you're over 18 or you live in America, that's 18). Since most people use 18 as the age, that gives a ratio of 11:18. 11 is prime so we can't simplify that. 150/11*18= 245.45, so basically, until she's 245.45 years old, she's still jailbait.
@@parallel4 it was a joke haha, but thanks for doing the math. Is the legal age for consent 18 in the US? That's bad. For us it's 16 and i think all the countries nearby are 16 and 14.
18 doesn't make much sense though, more people start when they are around 16 years old.
Hank, I have the exact same "Shark-Scale" It goes, cute, big, bigger, and LORD SAVE ME!
haha, it's a universally understood scale to be fair!
Big, bigger, & "what a beauty, wooohoooo"
AFishBicycle wut
I am so grateful that all the sharks on this list (except for the Wobbegong) live deep enough in the ocean that we don't need to worry about ever meeting them while swimming IRL.
"Sharks are not worms" -actual scientist hank green
Me: “oh geez! Thanks for reminding me hank! I get them mixed up all the time!” 😅
People who dislike were looking for megaladon validation.
haha, and they will unfortunately find it somewhere in some weird corner of CZcams!
Tell me about it
I'm not saying they do exist, but what makes you so sure they don't? You know we've only explored about 5% of our oceans and even less than that when it comes to the ocean floors. If we know of this many species of marine dwelling creatures in 5% imagine the total number of creatures in 100%... Open your minds to possibilities, don't be so absolute. Science is admitting it was wrong all the time. We don't know everything by far. Just because something isn't probable doesnt mean it isn't possible.
@@hippiechick3210
Sharks can't lives in that cold of the ocean.
Megalodon by it's size, it lives deeper than Globin Shark.
So it already won't survive because if the temperature.
*Open your mind*
@@I_Dont_Believe_In_SaladOh honey my mind is *open* 😋
If they've survived this long that means that they would have adapted and evolved over time. Nothing in nature stays the same forever if it learns better ways to survive and thrive. Even the human race is micro evolving generation to generation to better suit our needs. The physical bodies of these sharks could have adapted and overcame the inability to be in colder temperatures and adjusted to be able to withstand the pressure of deeper depths. Again, I'm not saying they're definitely still around, but I'm not going to close my mind to that possibility either. *The absence of evidence is not evidence of absence.*
Fun fact from a former aquarist. The Spotted Wobbegong can strike faster than the average human reaction time. If you get too close, they will literally bite you before you realize it. Also the tassels on their face help to break up their outline within coral structures, which is how most animals identify things (we notice patterns).
I find Sharks fascinating! The Wobbegonge looks like a plant. I'd like to see it in action,feeding. The Catshark is awesome!
Swim, surf, or dive in Australia and you might find yourself a little close the the Wobbegong action :)

Certainly no shortage of Wobbegong attacks
www.google.com.au/search?q=Wobbegong+bite+attack&oq=Wobbegong+bite+attack
I see wobbegongs nearly every time I go diving. They mostly are sleeping as it's daytime but I have seen them swimming around. I saw one eating an octopus it had killed once but I didn't see the attack. They do bite people a lot but it's mainly when people step on them or when someone sees their tales sticking out from under a rock and tugs on it (stupid thing to do as they are flexible enough to bite their own tails). It's rarely unprovoked when they attack.
@@theurbanshark1052 I agree, most 'attacks' are generally a response to accidental (or intentional) provocation.
Sometimes though, it doesn't take much to earn a bite on the butt.

@@crayzeape2230 that is true they can be nasty sometimes.
I remember going on a long time trying to convince myself that goblin sharks aren’t real until I finally had the courage to use my voice & do my own research ... in 3rd grade we had to do an animal “research paper” and I wanted to write about goblin sharks, when I told my teacher she called me stupid and said those aren’t real. I felt very embarrassed bc everyone heard and laughed. I was doing my own research at the age of 7 while my teacher who was in her late forties didn’t even believe in speciation, heck probably not even in evolution. Currently, I’m a third year biology major
My scale is the same as Steve Erwin's. Big, bigger , & "what a beauty! Woohoo!
I have a feeling he'd say "she's a beaut!" while swimming with a megaladon.
This was an awesome video, Hank! I love learning about sharks, and I was amazed when you talked about the Wobbegongs, having never heard of them/seen them before! Thanks for the new knowledge!

Don't bother. They're so rare, that filmed new encounters with living specimens are almost considered gold by people who studied them.

Muscle Hank has a few.
Over the Xmas break, I caught and released, 5 different types of shark. Smooth hammerhead, school shark, gummy shark, banjo shark, and a leopard shark. It was good to see lots of different species, I practice enviro tackle use, brass not lead, and hooks that oxidize in less than 12 hrs.
This time Hank was even funnier and more entertaining than always. Very well done and thanks....
I watch one video about sharks and youtube thinks I'm a toddler
I saw a video about tiger conservation efforts, that happened to include tiger cubs, and got a bunch of kids videos recommended to me by youtube.
No it's just Shark week xD
@@arthas640 COPPA is quaking

Like... all the recommended videos are baby shark related... because of course.
Yeah, what’s up with that?
Yeah.... I first thought my CZcams broke somehow. Anybody know answer to this?
I'm recommended more sci show videos
Do do do dodo
There was a guy who was criticized for posting a video of him smoking weed from a bong that was made from a shark skull to the song Baby Shark. So, it's bad that he had killed an endangered species. But the fact that he made a bong from its skull and played baby shark in the video shows...something else...bad.
Goblin shark: exists
Goblin slayer: excuse me wtf
me, at all these good sharks: adorable, what cute weirdos, I love these friends
Love watching and learning. Thanks Hank you rock!
I got a quest for you.
Goblins?
Yes.
Then let's go kill some Goblins then.
Mcdonalds lady: What size fry would you like?
Me:
*God help save me*
Oh my god, yeah, I'm pretty sure that first goblin shark picture is going to give me nightmares 😳
ETA: The catshark is pretty cute tho.
Wobbegone sharks are my absolute favorite shark to bring up. They're like a shag carpet that came to life, and their name sounds like an idyllic Wisconsin town where the children are above average.
No mention of the Cookie Cutter Shark?
The cookie cutter shark is an incredibly weird creature! Would've loved to see it in the video!
And Mako Shark. Those things jump!
ahh same i was expecting it to pop out anytime...
The cookie cutter is in my box of Graham crackers
I totally thought it'd make the list
Other notable sharks: cookie cutter, shovelhead, loan shark and Hyundai Tiburon
CZcams recommendations: baby shark, toys, etc
Me: CZcams ya done goofed... again
Cool! This video came out on my birthday, which was a trip to the aquarium, and I got to actually see sharks in real life for the first time this day.
I love how he explained everything. 😂
I laughed so hard. 😂
I’ve been watching your videos since you first started. It’s crazy to think about how much everything’s changed. Yet your videos bring back that worry free feel.
just keep swimming
just keep swimming

"That's what we do, we swim!!" 😃
Well done Sci Show team, that video was especially interesting and funny!
Before watching I hope one of my favorites the thresher shark is in this list.
Edit: Wow it was the second one, letz go!
Thresher sharks have been my favorite shark, and one of my favorite animals since I was in 2nd grade and had to write a report about a shark species for winter homework. Probably the longest I've considered something my favorite.
Haha. I wrote one on thrashed sharks too. As my favorite animal in like 3rd grade or something. Still probably my favorite. Along with red pandas.
Yea! I live on the SW coast of Australia! Seen a few Noah’s as I love to free dive for abalone and crayfish (lobster) . Lots of seals and even more great white sharks. They are a very efficient and intelligent predator. I’ve bumped one off and swam at speed from a few. They are not to be fkd with. Most people have no clue they are there until the teeth sink in. Evolution has provided them the perfect camouflage. Blue grey skin on top, bright white belly, as they hunt from below, thrusting upwards to strike, like I said most don’t see the coming. Come to Australia for a holiday but, be smart.
All this time I assumed tail whip was a crappy move.
Threshers were my favorite shark when I was a kid!
Me too. They were my favorite animal. I did a report on them as my favorite animal in like 4th grade.
Most kids love dinosaurs when they're little. I was fascinated by sharks. And the thresher shark was always my favorite.
Dude, what about the ninja lanturnshark, the cookie cutter shark, and chimaeras?
Chimaeras aren't sharks
Chimaeras are *NOT* Sharks. They're closely related to Sharks.
@@syedzafran2682 Thanks bro......I actually did not know that
Heicpion is more closely related to chimaeras than sharks
@@p-26gang91 heicpion? Did u mean the extinct shark helicoprion?
I always loved the thresher shark ever since I went to the birch aquarium on a field trip when I was young. I thought it was so cool that a shark could be like a whip. Very cool to see it get recognized
Every single "up next" recommendation from CZcams for me is a variation of the "baby shark" song.
Same
ive seen so much animal planet and youtube videos on animals, and i'm still often amazed at some creatures still alive today that ive never seen. The ocean is amazing.
Number 1: The Sharknado
you didn't even watch the video smh
Nad-Nado
I will always respond to your comment
The most realistic shark movie ever made
Don’t even, dude.
You should’ve mentioned epaulette sharks, they can walk on land! They’re extremely dangerous if you happen to be a small tidal pool crab, but pretty harmless if you’re human-sized 😁
new idea to movie the Sawshark Redemption.
I think it is amazing animals like the thresher shark somehow naturally know to use their tail as a whip for hunting.... I mean, other sharks dont do this, they are not raised by caring parents that teach them. Yet- they just know! I think that's very cool!
What?! No cookie-cutter shark?! OUTRAGE!!
Me: Why did I like Scishow in particular...?
“Big, Bigger And.. gahhelpsaveme”
Me: More please
Clicked on the video cause I saw what looked like the Greenland shark, still one of my favorite sharks ever
The wobbegong is also one of the few sharks that can bite its own tail (so don't try to grab one).
It also locks its jaw when it does bite down, essentially ratcheting closed (it's a shellfish eater for the most part, and this mechanic helps crush the shells) - the jaw only relaxes once it has crushed its prey.
You know what is really funny? Sharks with human teeth.
Maybe we have their teeth?
And the teen sharks had braces
Homodon should be it's name = human teeth
Great episode! Hollywood makes some fun stuff, but nature has so many more interesting things for us all to find. Loving the show. Keep up the great work.
I work on a trawler, we once caught a very big thresher. When in came in the boat I only saw its tail, it was so long I thought it was an eel
I learned and enjoyed this so so much! Thank you for enriching my life
I am concerned about youtubes video recommendations....It gives me kid cartoons to look after this one?!
I love how Hank is trying to look formal yet he is wearing a pizza shirt
Wobbegong that's Australian isn't it.
Yupppp
What gave it away?
Yes. My favourite shark.
See them all the time in Sydney.
Yeah im actually writing a report on them
In 10 minutes you covered more cool shark stuff than other channels do in a week. Nice.
8:31, how the hell does blue light, one of the most easily attenuated wavelengths of visible light, make it deep into the ocean? Shouldn’t it be red?
Hank saying "sneaking up on its prey. Extra super creepy!" Is why I love Hank. X-D
What is the average sharks favorite movie

A little surprised you didn't borrow Brit from the other Complexly projects she does to host something about sharks.
After your woebegong section I had to put you on hold and go look for pictures of one. They are amazing, such graceful swimmers and when you see their patterns they are awesomely beautiful. They call them carpet sharks but I've never seen a carpet that lovely. Their "snatch" is way scary though, so fast and such a big mouth! Eeeekers. They don't chew, just swallow it all whole. As always SciShow opens my eyes to something completely new; thanks guys and gals!
Heck yea, scishow uploaded!
Great analysis of unusual shark adaptations! Loved the sci-fi comparisons too.
*NOM NOM*
So much better watching this than the Super Bowl!
Maan were is cookiecutter shark. It's weird enough to be on this list.
dude, this guy and his brother are amazing
8, the human shark
3:54 for reference
The top view of the shark looks like an old man who saw a kid but the kid was doing something he hate.
