Shout-out to Bill Simpson for his help in the production of this video and lending us the fossilized shark specimens for the shoot!
We want to thank Ray Troll (www.trollart.com/) for generously allowing us to incorporate his incredible illustrations in this video!
The Idaho Museum of Natural History and the Idaho Virtualization Laboratory at Idaho State University is doing awesome work and they let us use the CT-scan of their Helicoprion for this episode, which we are very grateful for.
Special thanks to David Shiffman (@whysharksmatter) for his help, support, advice, and fun facts about sharks!
Additional thanks to Joe Hanson (itsokaytobesmart) and the folks at PBS Digital Studios for helping to put this great series together. :)

Just went shark tagging last month, and it makes me so happy that you are countering the horrors done by the discovery channel as far as media attention. I love sharks so incredibly much, and wish there was better educational media attention to them instead of sensationalism and fear-mongering. Thanks.
Sincerely,
A future marine biologist and current shark enthusiast
It's not fair to go tagging sharks! All you have to do is get in the boat or on dry land and they can't tag you back. If your going to play a childhood game with sharks at least pick one that's fair like Marco Polo.
love the Steve Zissou look! Life Aquatic is one of my favorites!
I didn't think it was possible, but the Wes Anderson opening made me love this channel MORE. Thank you!
A year or two ago I read about research that attempted to explain the helicoprion's "buzz saw" teeth that concluded that the "whorl" likely rested in the back of the throat with the teeth pointing inward to guide prey further into the mouth and prevent it from escaping. The research done at the Idaho Museum of Natural History is just one of several different conclusions made about this rather intriguing fossil through the scientific process and shouldn't be taken as hard fact. The mystery of the helicoprion may continue to spur interest, creativity, and scientific drive for many many years to come and THAT is awesome!
I saw your Steve Zissou reference...and your incredibly informative episode loaded with other Wes Anderson-isms it almost hurts.
I'm absolutely in love with all of these shark-themed episodes! So well made :)
I wonder if like modern sharks the coil was meant to replace worn teeth. So the smaller coil was inside and as the shark grew and ate they would move to the outer area replacing teeth as they went. Like beaver's upper teeth constantly grow, but more like modern sharks where they are constantly growing and replacing teeth.
Curious... and we may never know.
I was thinking something along those likes as well, especially after the last drawing was shown.
Yeah I wondered that too. But it still doesn't explain how they really managed to eat without an upper set of teeth... Unless they just gripped stuff against the top of their jaw?
Radish Raccoon
Sperm whales don't have teeth in their upper jaw but do have teeth in their lower jaw, so maybe they ate squid-like things.
Oh, that's really interesting!
OBD Tortoise That's an interesting option! The first thing that popped in my mind was maybe they used it like the rasp of a snail to get into hard-shelled creatures.
I love the Wes Anderson-style of the video!! So happy you're making these videos, really interesting stuff!!
I saw a great exhibit on this very thing at the L.A. Natural History Museum just a couple weeks ago. It blew my mind, and I'm eager to hear more. Yay science!
I have to respect Michael Aranda , he used the music that was in my marching show my freshman year!!!!!!!
Great stuff, Emily. you're still my favorite educational channel on youtube and I subscribe to a lot of them.
I love the idea of megalodons I hope we learn more about them.
The Life Aquatic with Steve Zissou mock! You guys are wonderful! :)
Nice choice on the music! Carnival of the Animals!!
Tom McNamara really did some gorgeous film work on this one.
Ha, that opening shot! I felt like I was watching Jock Cousteau!
Why the Discovery channel thinks it has to manufacture mystery when there are organisms like the helicoprion still left to untangle is beyond me. Thanks for showing us how real discovery is done!
Love the "Life Aquatic" references. So cute! :)
i love the format of this episode!
Oooo, I really liked this episode. Mystery, suspense, cliffhanger!
The Wes Anderson is strong in this one. Loved the video--keep up the great work!
This was very interesting! Also liked the choice of music - the piece "Aquarium" by Camille Saint-Saens fits the purpose. Is it just me or did you just up level up the production value? The videos have been great before, but now they seem even more... balanced. Anyway, keep up the awesome work and happy shark week to everyone (especially the sharks)!
She's channeling The Life Aquatic this is just too wonderful.
So excited for more of the brain scoop's shark videos!
Loving the Wes Anderson's feel and references!
HELIX FOSSIL
PRAISE HELIX
I just thought the same :D
SILENCE. THE INFERNAL FLARERON WILL SEND YOU ALL TO PURGATORY.
I knew it. I fucking knew it!
SUBMIT TO THE WILL OF FLAREON, PAY POKEDOLLARS, OR FAINT!
Hey, Emily (or anyone else who might know),
I noticed the genus "Carcharacles" used in the video for Megalodan.
Has there been a consensus yet for which genus Megalodan should be classified in?... Or is "Carcharodon" still acceptable?
You talk with your hands generally, so it's funny to see you talk while you're holding something. Your whole body moves as if you're moving your hands even though you can't.
Fascinating! That's some crazy mystery...
yay for real shark week!
Love your show! :) I think I've seen every one. Keep them coming!
Um, a little off topic, but...
I have found an unusual plant along the roadside leading to my house.
The flowers are identical to the common sweet pea, however, the leaves are long and spear shaped rather than the legume type leaves of normal sweet pea flowering plants.
This plant also produces seed pods very similar to peas, but the seeds do not seem to mature. Have you or any of your friends heard of such a plant?
I also have, in my backyard, an elderberry bush that has bright orange, translucent berries when ripe. The flowers and berries are exactly the same as a common elderberry except for the color of the berries. This bush flowers and sets fruit nearly a month before the usual purple elderberry. Strangely, the orange berries taste exactly like the purple ones, and do not stain your mouth. Perhaps this is a sport of an elderberry plant...?
Perhaps Miss Niezgoda would know?
You had me at the Zissou music. Great video :)
Loving the format of this video. It's very Wes Anderson.
I'm loving the shark week without made-up documentaries. It's a shame that a RUclips channel has better and more educational content that Discovery channel.
Can we do this every 365 days? Because I'm enjoying learning more about sharks
I can't believe it took me this long to figure out that whoever edits is a big Wes Anderson fan. The Life Aquatic is strong in this one. =)
That is mysterious indeed! Looking forward to rest of Legit Shark Week.
was the red beanie a small reference to life aquatic?
This is what we need for Shark Week every year. Not what the Discovery Channel keeps putting out u.u
With that red wooly hat you could be part of team Zissou.
This is some next level Beauty and the Beast music. Love.
Alexander Petrovich Karpinisky... most russian name I've ever heard
also
all hail the Helix fossil!!
I want to know the secrets of the swirly-toothed one! This is more suspenseful than any sci-fi show created for The-Week-Which-Must-Not-Be-Named.
Was this filmed in a room of fossils? That would be such a cool room to explore. I also liked the intro of this episode (the one after the standard Brain Scoop intro).
Music: Aquarium from Carnival des Animaux, by Camille Seint-Saens
Highly recommend it.
Saint-Saens: Carnival of the Animals~Marche Royale du Lions (March of the Lions)
I have many shark teeth in my fossil collection, including a 12.7 cm (5 in) long Megalodon tooth. :)
No teeth? Maybe there is some kind of tongue, and the toothy whirl might be evolved from that. Or the toothy whirl might have been used to harvest kelp beds or something.
Hey Emily! Love the show!
If you had the chance to travel back in time and dissect any extinct species, what would it be? :)
That's all the Shark Week I need
Are you going to make a video about the evolution of sharks? Like the very first ones to the ones of today?
I get that shark teeth and shark scales (or dermal denticles) are related. But I'm curious as to the evolutionary history. On SciShow, it was mentioned that sharks and bony fish diverged before the evolution of scales, so shark scales are different from the scales of bony fish, because they don't share an evolutionary link. Sharks had to use the existing genetic material for making teeth to make scales. But here, it is said that shark teeth are effectively modified scales, rather than shark scales being modified teeth. Can someone clarify this?
thx for this awesomely ha bisky vid i love learning so much and sharks are so kool
Great episode!
You're better everyday, @brainscoop!
The start of the Video reminds me so much of "Moonrise Kingdom" :)
Thumb up for Saint-Saëns
Don't you mean…Shark-Saens?
I'll see myself out.
David Shi or... super-saens?
God I love your videos, Emily! I learn soooooo much!
Hmm, wouldn't those spiraling teeth be sort of like the rolling teeth sharks have, to eternally regrow? They probably just grew larger and more to the front as the frontal teeth were getting damaged. - That is how it works in white sharks, right? I at least remember seeing that in a documentary but it was years ago.
So either, this narrower, longer spiral evolved as a side-offshoot to that much more compact rolling tooth design (if that's how it's called, which it probably isn't), or it's actually its origin, later compactifying and turning into the more modern form we see today.
That actually makes a lot of sense.
so is the assumption that the smaller end in the middle of the spiral is kinda like the backrows of "modern" sharks? but only in a singular row? maybe the tissue underneath had a certain amount of inherent tension, and as the animal decomposed, the remaining hardened row of scales kinda rolled up?
Thank you very much for also using the metric system.
Please tell me the hat was a Steve Zissou reference.
Was that intro a tribute to The Life Aquatic?!!?!
this entire shark videos series has a lot of Wes Anderson influences
I thought so too
0:06 What's this song called? I hear it now and again, but I don't know the title.
love the music
Maybe you (or someone here), can answer this but I know the full name of megalodon used to be _Carchardon megalodon_ but more and more now, I'm seeing it referred to as _Carcharocles megalodon_ instead. My question is why? Is it not a member of the family lamnidae and if not, why?
i love it! good stuff, gets me brain goin
Where is the music from? I heard it in the Singapore Aquarium.
Why do I feel Emily is like a more sciencey Wes Anderson? Because that is amazing
Loving the Cousteau hat.
I really, really love the Wes Anderson vibe.
I'm convinced the Helicoprion is an ancestor of the Goblin shark. Possibly with a bifurcated lower jaw with two whorls of teeth. The spiral was a more primitive means of tooth replacement and it probably had upper teeth that were either less osteocized and didn't fossilize, or we simply mistake their fossils for another species. Perhaps they had an elongated snout and the teeth did unroll? How do we know they stayed in place? I'll have to do some reading on that I guess.
God I love this channel. Team party horn here.
I really enjoyed Several Consecutive Days dedicated to Predatory Cartilaginous Fishes. Will you be doing Several Consecutive Days dedicated to Predatory Cartilaginous Fishes annually? Several Consecutive Days dedicated to Predatory Cartilaginous Fishes seems like it would be a good recurring feature on a yearly basis.
Nice video!
OKAY you have my undivided attention. SHARK ON!
Toothy Whirl was my favorite grunge band in the 90's
Team zissou represent!
What is that starting song? I recognized it but i don't remember it's name.
Aquarium from Carnival of the Animals by Camille Saint-Saens.
it also sounds a bit like some of the music from Beauty and the Beast
As Nadiact said it's Aquarium from Carnival of the Animals. A bunch of the music from Camille Saint-Saens is used in the cartoon Ren and Stimpy. And there was a Looney Tunes episode dedicated to it.
nadiact1000 That's right; thank you. I always get it mixed up with Holst's Neptune--they have very similar feels, at least to me.
What the music in the background at the beginning?
The Life Aquatic with Steve Zissou yay!
The first 30 seconds reminds me of a Wes Anderson movie!
What was the music used near the beginning of the video which almost universally used to denote being underwater?
It's Aquarium from The Carnival of the Animals.
That is the glorious musical piece composed by the French Saint-Saens and It is called 'The Aquarian'.
I think it was used in a benjamin button trailer as well and no i dont know what its called either but look for the trailer and maybe you'll find out.
Wait what happened to carcharodon megalodon? Why did it change to carcharocles megalodon?
Yes this was scripted, but Emily, You Champ! Good work, great video! LOVE this video!
Personally, I always choose the Dome fossil...
Okay, which one of you had the idea for the Wes Anderson reference? Michael? Emily?
Like the discover channel, But better!
The intro reminds of some song from the dutch entertainment park de efteling
Wait - Hank Greene says that shark scales are basically little tiny shark teeth. Why don't we find shark skin fossils?
Was that lake Michigan standing in for the ocean?
Yeah, but wouldn't it be sad/hilarious if we had actually flown to either coast just to get a shot in front of a real ocean?
Next Up after WHEN COCONUTS ATTACK: are there REALLY SHARKS in LAKE MICHIGAN?!
I've never liked any ocean as much as I like lake Michigan anyway.
No sharks, but there are zebras!
Well...zebra muscles....
Thank you for the Saint-Saens!
Those are some really powerful binoculars.
what's the name of the piece of music after the theme song?
It's Aquarium from The Carnival of the Animals by Camille Saint-Saëns.
thank you!
2:49 All of those look pretty sweet.
I've never understood why people show the view from binoculars as two separate circles when it actually forms one image when you look through them..
Because otherwise you have to label every binocular shot "binocular shot". It's a time saver, really.
Plus its supposed to look like the film The Life Aquatic, which is very stylized and quirky.
They're actually just looking through 2 cardboard paper towel tubes.
JoyLyte You've got a really good point, but the better question would be - why am I still wearing my glasses and using them to stare at the cameraman? *mooooovie maaaaaagic*
*****
I love how the whole world looks like a National Geographic documentary while looking through binoculars. Do you agree?
:-) just wanted to say that moose (at least the one found in Northern Europe) only has teeth in the lower mouth and a bone plate in the upper mouth, that it uses to ground the twigs and leaves it eats. Maybe the same for this shark?
I wonder how excited the first people to find giant or spiral teeth were.
so cool!
I love that Emily can't move her hands so she does a little "shuffle" throughout the whole video :P
How do they know the coiled teeth were from a shark?
