- เผยแพร่เมื่อ 29 ก.ย. 2024
- One group of sharks alive today, the Hexanchiformes, might be the only living shark order to have survived since the Paleozoic. This ancient lineage of fish is incredibly fascinating, including both the Cow Sharks and the Frilled Sharks, and in this video we investigate their biology and evidence for their evolutionary history.

Sharks often receive the same treatment as crocodilians in being labelled ‘living fossils’. Great video!
Fascinating topic, thanks Ben!
I'm wondering how cow sharks got their name.
The spots under its mouth?
This sure was another lovely Ben G Thomas video once again about some awesome species of Shark,and this time it's on the long lasting Hexcanchiformes,my favorite group of sharks.
Also hope y'all have a great day
Shin Godzilla shark
6:20 Thanks for using my drawing! It's crazy seeing one of my little doodles show up on one of my favorite youtube channels :)
Congrats :D
I wouldn't call that a little doodle. It looks pretty awesome to me! Especially considering the research you must have done first. 👍
We used to draw frill sharks on the library books pages. But no of us bragged about it, cause it was frowned upon
@@salvagemonster3612 Your point being?
cow sharks are adorable, and look like they're whistling along as they hunt underwater
Cow Shark: No thoughts, head empty
Frilled Shark: I will be seeing you in your nightmares
The shark side of marine life is a pathway to many evolutions, some considered to be prehistoric
Have you ever heard the tale of Shark Plagueis the Wise?
@@liamjohnston2000 have you heard tragedy of shark tale
@@liamjohnston2000 I thought not, it’s not a story the cetaceans would tell you
What am i reading?
I see what you did there you silly goose.
The frilled shark is what shin godzilla is inspired from so it really is prehistoric
I was wondering why it looked so familiar
That explains why that thing looked so familiar. It was a good inspiration for the most terrifying Godzilla.
In godzilla movies
Past people (idk what it must be named) thinking godzilla is their god
Sooo frilled shark is very myhical or something in the past?
shin godzilla has the body of a pixar mum
@@marcellosirait_ No. Godzilla was never a religious figure. Shin Godzilla from 2016 was designed off of frilled sharks.
Sixgills are nowadays often seen as scavengers for their habit of eating whale carcasses, but they really feed on live prey much more often, and visit cold, shallow temperate waters surprisingly often for this reason.
Sevengills also deserve more attention as the apex predators of shallow, mud/sand-bottomed bays and kelp forests. They’ll even hunt cooperatively in California to corner and kill seals.
What about Eightgills?
Sharks but with increasingly improbable number of gills
I see the, more as JERKS! They bullied me in Gym class
@C K Southern sleeper sharks have been recorded to attack adult male elephant seals as well.
I mean nothing wrong with scavenging whale carcasses once or twice a year, it’s a good strategy.
Finally someone is saying it. These are not your grandfathers’ sharks.
Wait what? I thought the whole point is that these sharks have been around since before our great grandfather's?
These aren't your grandparents sharks. These are your great great great great great great grandparents sharks.
@@zehkiel8018 No... They are today's sharks. They may have similarities with their prehistoric ancestors but they are the current sharks. The title is an oxymoron.
@@deathproofduck6897 it's a joke my man.
@Khail Kupsky That's true, but that's just a matter of shark culture. Your fancy hat and cane carrying sharks could never have gotten where they did without their bigger, club wielding shark ancestors.
Great video as always! 5:14 Also, would the similarities between modern frilled sharks and Xenacanthus be considered a case of convergent evolution since the two aren't closely related?
Loved your video yesterday
Thanks so much! And yes I think it must have just been Cope interpreting the convergence between the taxa and mistaking it for some kind of close relationship.
Sharks: more than just the great white
more than just megaladon as well. The very first shark goes way way way back
Merch idea: join the Shark side, we have teeth.
I wish i had this dude's jawline lol
Who wouldn’t tbh
Nothing is primitive. It's just well-adapted.
basal, then.
I interpret “primitive” as more a way to describe how something looks.
@@DustyHoney yeah I thought he used primitive as describing that it was similar to more ancient sharks rather than an insult.
@@John_Dusty Same.
@@John_Dusty ofc someone with your profile picture is interested in what lives in the ocean.
I was showing this to my little brother, I am recruiting him to the shark side. You need a "shark side" shirt.
No offense, but not every single thing needs its own branch of merchandise
@@leopardgeckoonsteroids7012 yes, but I want to see that shirt.
The shark side of marine life is a pathway to many evolutions, some considered to be prehistoric
My brother is learning to be a shark scientist, we both love shark week.
Welcome to the shark side.
Man.. the frilled shark is awesome! Pretty cool to see what primitive sharks looked like millions of years ago. They must be extremely resilient.
I’ve always had a fondness for the blunt nose sixgill, growing up in the PNW you can sometimes spot them off the pier in Seattle
lucky!!!
We have a nursery for them in the seattle area. Huge study was done on it a few years back. Made for some amazing dive footage too! :)
@@halleyluther9462 nice!! very jealous
Nope. They have been looking for you for years. They know what you did! They are coming for you. Next evaluation step. Walking into your apartment complex
Holy sh*t his jawline
I was thinking the same. I love this channel but never noticed before.
Imagine having Morning sickness for 3 and a half years
Imagine being married to someone who’s pregnant for three and a half years!
😂
@@CorvoFG ....The relatives of my brother's wife have spent 10 years pregnant. They say that's their "job".
Something Mildly Homophobic Think about it.
What about Greenland Sharks? They can be pregnant for up to 18 years…
I saw and studied a Clamodoselachus anguineus male, that was one of the best things in my life.
And then we caught it and eat it
@@salvagemonster3612 How it tasted? Was yummie?
Great video guys. There was just one small error that i saw. There are actually 3 species of sawshark that have 6 gill slits. The first known sixgill sawshark was renamed Warren's Sixgill Sawshark (Pliotrema warreni), and 2 other species where discovered recently, being named Anna's Sixgill Sawshark (Pliotrema annae), and Kaja's Sixgill sawshark (Pliotrema kajae) respectively. Other than that small detail, the video was excellent. Keep up the good work
Thanks for the kind words! Ah yes I saw that there are actually 3 species now, that's why I made sure to note it as the genus Pliotrema and not say species :)
@@BenGThomas ok cool. I just wanted to clear that up. Sharks are by far some of my favorite creatures, and i was ecstatic to find out about the discovery of those two new species. I just wanted to share that with everyone. Thanks again for the excellent video series for this year's shark week and all the previous ones. Great work
The video about my fave shark order finally came in! 🙏🏼🙏🏼🙏🏼
Imagine encountering that in the wild…
No wait YOU CAN?????
The sixgill and sevengill sharks seem alright, but goddamn that frilled shark is a living nightmare.
the only constant thing in the world is change...
sharks: "yes, but also no..."
me: aww "cow shark" is such a cute name, i wonder why it's called that!
cow shark: o____o
me: i see
The nurse shark is the oldest shark species that still exists today. It’s been around for 112 million years
*Grey nurse shark
People call them Living Fossils for their appearance, of course the genetics have changed drastically over time, but not much in terms of appearance.
Ohhh thank you we get it
Sharks and gators the ultimate body plan lol
Tbh 2:36 looks more like a sock puppet than an aquatic predator.
Even with their diversity, I still think it's fair enough to say that basic shark anatomy has remained relatively consistent considering their several hundred million year lineage. That's definitely not to say there aren't or haven't been significant changes, it's just more-or-less easy to identify a species as a shark in most cases, I figure.
‘Remained fairly consistent’
Scientists: we’ve found a species of armored shark with 3 long snake like heads, wings, and long whip like tongue used for capturing prey like some lizards, it’s species is called the 2020 Shark.
2021 Shark: a deep sea beast that burrows down into volcanic vents to ride the lava flow during Eruptions to feed on whatever is nearby the lava, the female sharks have wings.
I remember making a diorama of a frilled shark in 5th grade science, such a fascinating creature
omg first. nice video
First nice video? Ben has done a lot of nice videos
Weird to say that the video was nice when it’s not even a minute old
@@misterflibble6601 i meant first, nice video
@@almazzagitov9799 also from what I've seen so far, its nice.
@@almazzagitov9799 plus its 4 minutes old
Shin Godzilla approves of this video!
Finally something actually educational on YT
Turn on subtitles and you get "thrilled sharks". I bet they'd be thrilled with that name..
I think the Greenland shark is my favorite but also the most misunderstood
misunderstood
oh! I know that chick
I’m so happy to see my frilled bois getting some attention 🥰🥰🥰
The sixgill bluntnose beat on me in Endless Ocean 2 on the wii in the depths area so I have a vendetta against it.
Ben "Gdunkleosteus" Thomas
i got startled when your face came on screen lol
i’m so used to only hearing your voice
Fun fact about the frilled shark: Frilled sharks have 25 rows of teeth, which all together contain 300 teeth! This allows them to keep a good hold on there prey, like squid
I like your shark collection
They'll probably survive the Anthropocene also.
I certainly hope so
Sharks are important anyways.
We're currently in a *Mass Extinction Event (Anthropocene Extinction)* with rapidly changing *_Oceanic Temperatures/Chemistry_* caused by *Global Warming,* and we're already observing _behavioral shifts_ in multiple *Shark* species, as they change their _terratorial/predation habits_ to follow prey species. This will inevitably lead to speciation & intriguing new forms of *Shark* coming into existence.
I reckon you really ought to do a special video about this.
Depending on where *_"Sharks"_* can be said to have originated, there really are some extraordinary (& frankly bizarre) variations & body forms that which have evolved to fit multiple niches of predator. This makes their lineage both an extremely resilient survivor & remarkably flexible adaptor to newly opened environments (following extinctions of competitors).
The Greenland shark, Somniosus microcephalus, internally gestates eggs and the gestation period is estimated to be between 8 and 18 years. Then again, they only reach reproduction maturity around 150 years of age, but are believed to live for 500 years.
You know, I'm really glad I don't live near the ocean
*'eavy bri'ish akshent* oi, bruv. Wots the maorst preai'istowric shyahk aloive terdaiyre?" *Holds up a silly picture of a chubby shark* "this one"
The frilled shark is definitely my favorite shark
Bluntnose, Broadnose, Sharpnose...?? 😆🤣🤣
These scientists need to employ a little more imagination in naming these...
Thanks Ben for another great video.
Much Appreciated! 😎👍🏼
Hah I've thought that as well. But I mean, especially with requiem sharks sooo many with practically identical features except something minor; so can you really blame them for calling them finetooth shark, spinner shark, small tail shark, etc... 😆
no offense meant: speaking thru teeth is one of British accents or is it a very individual thing?
It's possible that Megalodon looks more like a Cow Shark than a Great White?
with those big eyes, you can hear echo from Japan: SENPAI! LOOK AT ME BAKA!
If i saw a frilled shark i'd stomp on it with my big work boot with metal plates until all that is left is a brown stain on the floor.
I don't want those teeth anywhere near a 500km radius from me
I wonder if it's called McMurdonus because it was found near the McMurdoc scientific base in Antarctica...
could do with stock images of sharks swimming rather than your face bud, ngl.
They look like a living wet specimen. That deteriorated, soggy look
Goblin sharks are also relics from prehistoric times, just like the Sixgill and Frilled shark.
Thank you for this video! The frilled shark is my favorite underwater animal, and I haven't seen many videos about them. Always looking for good frilled shark content!
I dont think facecam is suitable for informational videos
Since the early Devonian?! I mean wow! Awesome indeed.
-Hello scientist
-Frilled shark! What are you doing so near the surface?
-I’m allowing you to learn more about me
Hello why don't you start your on shark month
Dey should do daggernose shark and borneo river shark for shark week
It was 250 known species when I arrived ..
Please do a video about Brontoscorpio!
Interesting! Good job! Thank you♥️‼️☮️🕉💟
I bet my shirt that we'll discover another species of Frilled Shark by 2050
I'll take that bet. Keep that shirt clean
And hopefully we will discover even more interesting and massive sharks/creatures in our oceans and rivers too as I’m sure we will! Only 10%, if that, of our oceans have been discovered! I also believe that aliens may be living underwater as there are documented videos and photos from our military/government of crafts hovering over water, dropping into the water without a sound and the most fascinating is a craft flying above the ocean the going underwater, splitting in two, with both crafts then going above sea level again and then back into one form!
Also, I have strong feelings that the Megalodon is still around and has just evolved to live in the depths and to avoid humans as I’m sure they’ve become a lot more intelligent if they’re still around. I also believe the Loch Ness monster, or the dinosaur Plesiosaurus could be around as well and has also evolved and adopted traits to live very deep in the water. It also could be a giant eel-like creature.
@@JohnnyHandsometm Remember to take your meds, bro, but I do share your cautious eldric optimitism.
Nobody:
Bichirs: rookie numbers
Fascinating information. Thank you so much for providing yet another excellent episode.
0:20 Ooooh you have a dozen books on dinosaurs. You’re soooooo smart ooooohh
We think fish as primitive but under water their pretty advanced their communication signals under water and . Their more then just brain stem . They have the hemisphers. Hypocsmpua and basil ganglia . The neo cortex is simply the neurons on the surface on your brain fist still have grey matter neurons
i wish i knew sharks were this cool sooner
shork
Shork pog

the frilled shark looks like a dragon
4:50 imagine seeing this while swimming
You should do a green screen and talk about these animals on them
I am not trolling or trying to cause any fireworks, but I would just like to clarify something regarding the use of terminology. Biologists don't use the words "primitive" and "advanced" anymore. Those words carry ethical value implications of better and worse, which are irrelevant to science. Instead, they talk about "simpler" vs "complex" or "derived" life forms. Sharks are incredibly amazing animals. They have fascinated me since I was a kid. I am happy that more people are coming to understand how astounding their biology is, and how important they are. Ho hum, if only snakes could get the same rap...
And I say all this while I myself, paradoxically, am a living contradiction. As I get older, I get simpler and simpler. Practically a vegetable now.
Love your work, guys. Great job!
Sharks older than dinosaurs? B*TCH PLEASE
they're older than trees xD
It looks like shin Godzilla you can really see Toho got inspiration from these frilled sharks
Shin was a mutated frilled shark
Have you ever said a word so repeatedly that it starts to NOT sound like a word?
I feel like that's going on with your hairstyle xDDD
It's looks great and perfect but the more I look the more I realize what a strange hair style it really is (as well as all hair styles)
(I'm not trying to talk shit just noticing xDD)
How these sharks teeth are linear instead of around the mouth. Just like that one acientshark with one large Single saw like blade bottom jaw. Forget the video you did. But the teeth are so strange.
With the modern counter parts having multiple rows of linear teeth.. I don't know much but the similarity is unusual....
The megalodon was a prehistoric shark. That species of shark is definitely not around anymore.
Was that a picture of a whale shark? that's not a shark or whale.
Wow very cool. I've learned more watching your channel compared to any class in school. Thank you
Great video! Didn't a deep sea cam capture a 6m 6 Gill shark earlier this year? Or was that unconfirmed?
yeah, the cow sharks were shaking a fin at yelling at those upstart , get offa ma lawn, you kids!, for a long time.
I don't know why but there is something extra freighting about more primitive animals, those fix look like instinct to eat with teeth.
Wow. I’ve never heard of a cow shark.
Whoever named it that should go to an eye doctor.
I dont think I have ever heard anyone call sharks primitive animals.
Why is thallassophobia a thing?
I want to watch this without being jumpy .....
Frilled sharks are so ugly, every time they watch TV, the channels change themselves.
Like, I know life is precious and stuff but... this frilled shark is the worst thing I've ever seen.
frilled sharks kind of looks like how sea serpents are depicted in old drawings
Can anyone give me an explanation of the frilled shark's teeth? What kind of feeding does it do?
Could you do a video on the weird deep sea fish that has the upwards facing eyes that look like they're in a fish bowl in their head.
Told you
