Fun fact: selachimorphology is the study of shaaaaaarks. I've been trying to get an interview with Dr. Chris Lowe since May and as it happens, we may finally meet up tomorrow. Hopefully this'll be in time to turn an episode around for Tuesday, co-inciding with SHARK WEEK. (I may have to skip Comic-Com but I mean, Shark Week, y'all...)

I'll ask as many questions as time allows and thank you so much to everyone submitting! 

Cross yer fins we pull this off.

Is it true that shark babies sometimes eat their siblings in the womb?

Lora Donnelly

Recently they found a houndshark with male claspers that was pregnant. Are there any other sharks or cartilagenous fish that are hermaphroditic?

Craig Minami

Did the protection of certain sea mammals like sea lions and seals help increase certain shark populations?

Mikey

I’ve seen a few videos recently of sharks enjoying scritches, do sharks have a type of pleasure center in their brains? I have so many questions and it pains me to just ask one! I love sharks so so much!

Jennifer Buz

can a shark "smell" my period in the water

Anna Thompson

How has modern technology changed how we study sharks? Where do White Sharks have their babies? PS super super excited for this! I love shark week and am so excited for my favorite podcast and my favorite nature theme to merge

Craig Minami

Also, have we done enough to ensure more sharks don’t get harvested for things like shark’s fin soup?

Zoe Elewitz

Are there any nice sharks, I'm slightly terrified of them... Also what did sharks evolve from?

Justin So

How aggressive are sharks, really?

Chloë Anaya

How have things like ocean acidification and other environmental changes affected sharks and shark populations?

Maren Mossman

All whale sharks I have ever seen tend to have other fish that latch on as they go on their merry shark way. Do other sharks have fish that do this? Are they just smaller, or is this a purely whale shark thing?

Aki

Do sharks communicate with each other? If so how? And what do they talk about?

Alicia Puritt

What determines how many rows of teeth a shark has and the rate at which new teeth grow in?? So excited for this ology!!

Bob White

Does a shark possess long-term memory similar to crows or are they more similar tsh?

Maren Mossman

Do you believe that “fish are friends, not food”? 🤪

Zoe Elewitz

Are there other animals living in the ocean that fear sharks the same way humans might fear a shark, or are they a potential predator just like any other fish?

OkayKellyRuss

So if you are actually attacked by a shark is your best move to poke it in the eye?

Tyler Q

Why did they make so many Jaws sequels, and have you seen them all?

Gabriel Mariscal de Souza

Is it true that sharks need to constantly need to move? And, how do sharks sleep?

Mike Awkerd

Are whale sharks known to attack humans? I was offered to swim with whale sharks in Mexico, but heard there have been three attacks just this month. Is this natural or due to tourists being too up in their grill?

Michael Gonzalez

How dangerous would today's oceans be if megalodons still existed? Would they be aggressive or passive to humans?

Radha Vakharia

Hammerheads. Why are their heads shaped so strangely compared to most other fish? Does it give them any advantages? Can they see frontways?

Neal Williams

What's with the fish that tags along with sharks like an annoying little brother

Evilh

Why are there so many types of sharks? I got my kids a comic on sharks and there is a ridiculous variety of shapes and sizes!

Ashley Perez

Is there any truth to the myth that if you punch a charging great white shark in the nose, it will swim away?

Zachary Brubaker

We're sharks actually dying at Sea world in the square tanks because they were stuck in the corners?

Anna Marie

Are touristy cage dives harmful to sharks? I think it looks fun, but would never do it if it was bad for their environment.

iolanthe

Everything about Megalodons!

iolanthe

How accurate are movie sharks?

iolanthe

Are movies like Jaws dangerous for sharks reputations?

iolanthe

Why are there so many different types of reproduction and birthing for different shark species?

iolanthe

What do we do about shark attacks?

Beth Frausto

Do sharks sleep? Do they dream? If so, what do they dream about?

iolanthe

tell us everything about shark lore and mythology

Beth Eicher

Are goblin sharks for real?

Blake Hawkins

Are nurse sharks really docile sharks? I swam with some years ago no problem, but recent stories make me think twice about doing it again. Is it that they can be aggressive, but decide not to or is the human interaction decreasing the “fear level” of these sharks?

The Project Project

How long does it take for a big white (or tiger, or making, or basking) shark to get that big? And how long are their natural lifespans?

Matisse Larocque

How do you think humans could interact with sharks in order for both species (sharks and us) to benefit from each other?

Al Martinez

There was talk for years about sharks not getting cancer and the studies trying to find out why and if something could be found to help humans. Did anything come from the studies? Are they still being conducted?

Al Martinez

Also what is the status of the shark population? Are we close to losing them and throwing off the balance of nature in the oceans?

Cody Woppenkamp

Serious question: How damaging to shark populations is the current practice of shark finning, and how can the general public put a stop to it? Fun question: What was the coolest type of shark in existence, and why was it the Megalodon?

Nessie

Do you think they will ever be able to keep a great white shark alive in captivity for awareness, conservation, and educational purposes? Or is it just too hard to create a stable environment with enough room and proper oxygen levels? I worry about them becoming extinct due to humans (pollution & poaching) and us not being able to save the species in captivity if needed.

Aria Salan

I live in Queensland, Australia where we have a huge bull shark population in our all our rivers - fresh water and salt water - and apparently happily go between the two. How do they do that?? Can other sharks do that? Also no one swims in the rivers here because of all the bull sharks and media coverage of the sharks. Are they really that dangerous? Do I really need to worry about my dog getting eaten while we're picnicking on the shore of the river?

Levi like the jeans

SO MANY QUESTIONS. YOUR PICK. whats their favorite shark and why? what has driven sharks to evolve to be so gosh darn good at killing? what are the biggest misunderstandings about sharks?

Greg

Even though technology seems to advance rapidly, information about Shark biology and breeding does not seem to have advanced very far. What are the obstacles that prevent scientists from learning more about shark breeding behavior and cell biology among other things?

Chris Butler

Is it true that sharks must keep swimming to get oxygen from the water, and if so, how do they sleep?

Thomas Pico

Is it true that sharks filter their pee and excrement through their skin? Is this why they have to be bled out through their jugular after fishing them out of the water? My brother says if this is not done it ruins the taste of the meat.

Euan Munro

I heard on QI, that a lot of the reason people are scared of sharks is due to ominous music played in documentaries (and major motion pictures) when they are on TV. I am personally tackling this by talking as the shark in a silly voice but this has a limited audience. Does Dr Lowe know 1) If this is true, and 2) are marine biologists trying to do anything to guide media outlets to use different music?

Euan Munro

P.S. My favourite shark to do a voice over is the sixgill shark as they look so derpy!

Kira Lichtenfeld

When I lived at the beach in North Carolina,the rules were don't swim at dusk and after, don't wear anything shiny and don't swim with any active cuts. Is there anything you could wear or a scent to have that would deter a shark?

JESSICA KAINZ

Can sharks sense stress levels like dogs and other animals? Like if I was snorkeling in the ocean and saw a shark and I got scared, would they know?

Becca Bee

Are sharks smart? Can they perform octopus-level feats?

TONY BRAZELTON

How many other ways can we die swimming in the ocean that we should fear more than a shark nibble? Or are we 100% justified to freak the hell out about sharks?

Steve Balk

Do sharks face the same rapid extinction risks similar to large land mammals?

Tracy Ann Lanier

How many people die per year from Shark attacks vs Tornado's?

Jack Kelleher

How fast can a white shark “close” on a person? What about the sharks swimming up rivers in Australia are they evolving to become freshwater sharks?

Keith T

Life goal: Swim with big, scary, but somehow cuddly sharks. What is the safest way to do this, both for me AND the sharks?

Colette Ayers

What’s your favourite named shark? I’m partial to the hammerhead so literal 👌🏻

Jane

Has he seen the episode of Nailed It on Netflix where they make a shark cake? It's hilarious and horrifying at the same time.

Jenny

Is there a good app or website where we can go to identify different species of sharks? A few years ago, I spent a day swimming around Looe Key (in the Florida Keys), and we saw several sharks close by. But I have never been able to determine their species and it has always bugged me!

Daniel Willard

What will it take to recover sawfish populations? Since they are live bearers, is there a role for hatcheries (minus the hatch)?

Christa Avampato

My 10-year-old niece, Lorelei, wants to be a marine biologist and she's particularly interested in sharks. What are some great resources (books, websites, places to visit, etc.) that I could share with her?

CheerfulGoldfish

Why do sharks go into a tonic state when they're flipped upside down? Does this happen with all species of sharks, or just some of them?

Emma Fiori

Alie, will you be in Monterey today (7/20)? I work next door at the aquarium and I would LOOOOOOOVE to meet you! Also, Chris Lowe is another of my heroes and I'm sooo excited to hear what you get out of him!

Emma Fiori

Oops, just realized there is another Chris Lowe in Long Beach who focuses on sharks... probably the one you are interviewing. But I'm still super excited!

Eva

Whale sharks: are they sharks or whales or just huge fish?

Kristen Burgess-Udall

What determines the differences in appearance of shark egg cases between species?

Reuben Clamzo

I'm really fascinated by the megamouth shark. Have there been any new sighting and have we learned anything new about them?

Travis DeMello

What are some of the most fascinating prehistoric sharks, besides Megalodon? What time period had the most diversity between shark species?

Brooke Shearin

Do magnet wristbands really work to deter sharks? I want to scuba dive off of my coast (NC), but I'm afraid to with all the sitings of great whites these past few years!

Tyler

Is it possible that megalodon is still out there somewhere? The ocean is pretty big and Jason Statham can’t be everywhere at once.

Sasha Chihak

I recently watched the Netflix Series -Sharks which was really cool. I never realized that there were so many different varieties of sharks and that they are related to ray fish. What's your favorite shark? I'm torn between epaulette sharks and whale sharks...not literally of course that could get messy. =)

Eva

Is it true that some sharks are "serial predators" and have attacked multiple people while other sharks are not as predatory of humans?

Anna Mc

Best way to not get bit by a shark when surfing?

claudia jones

What is your opinion of Shark Distaster Movies? (Jaws, Deep Blue Sea, The Meg etc) Do you think the evil man-eating stereotype (?) paints a harmful picture/makes people unnecessarily afraid? Do you think the 'Jaws Effect' poses a problem?

Sean & Josh Grandinetti

What accounts for the strange evolution of the shape to the hammerhead sharks skull?

Hilary Blake

How would you describe their intelligence levels and can sharks be trained and 'cultured' like how we have music and abstract ideas?

Kellothere

Where did that myth? About sharks having to keep moving or they die come from? Also, what's going on with the shark whisperer? What's he doing to make them Tigers roll?

Jaimee Drew

My 9year old Chelsea would like to know if sharks fart. Thanks!

Karla Rae

I don't know much about sharks but shit, if they're in perpetual sleep mode I need to know their secret. Cure for the common PPD?

Codi Schmitt

What is your favorite thing about sharks?

Donatellia Austin

I heard about sharks evolving to be more freshwater oriented. Is this accurate? How quickly can sharks actually evolve?
