We Just Discovered a TENTH Hammerhead Shark!

Hammerhead sharks are one of the strangest sharks the world has ever known, and now there are ten known species! Obviously, hammerheads are set apart from all other sharks by their bizarre shape of their heads which are called a cephalofoil, but why are they like that? Why are these sharks so strange? And now that there are ten known species, what are they and how are they related? Zoologist Clint Laidlaw will answer all of these questions and more, so let's dive in!

I'm pretty pumped for the extras video! Sharks, Star Wars, AND conspiracies?

[michaelwoller]

Can we remake shark week but with Clint in charge of everything?

[testogel]

NGL If I'd been asked to name a hammerhead species before having watched this video, my reply would have been that I thought "hammerhead" WAS the species.

[hiddentruth]

The large hammer is because there's a big nail in the ocean we don't know about.

[bitcores]

Even if I don't have a particular interest in a group of animals, Clint's enthusiasm just makes it interesting.

More REAL shark education in 30 minutes than the last 25 years of "Shark Week" combined... THANK YOU!

Aerospace engineer here! I would be surprised if the cephalofoil on the winghead shark being swept-back was to reduce drag. In high-performance aircraft and even airliners (who can cruise at or above mach 0.8), it reduces drag because it lessens the affect of shocks produced by the certain parts of the airflow becoming supersonic. This is why you only really see swept wings mostly in aircraft that are going very fast. Unless wingheads are going reaaally fast (sound is significantly faster in water than air, so I mean reaaally fast!), the cephalofoil is probably not swept back to reduce drag. My guess would be for better stability! To grossly oversimplify it, think of a shuttlecock. Even if you were to throw a shuttlecock backwards, it will always tend to right itself. This is because the combined affects of the aerodynamic (or hydrodynamic in this case) forces want to go behind the center of mass. By sweeping that massive cephalofoil back, it brings it closer to the shark's center of mass, reducing this shuttlecock affect (This is all a massive MASSIVE oversimplification! compressible flow and aircraft stability and controls are fascinating subjects, but I don't want to make it too difficult to understand)

Anyway, very happy to find out there's a new hammerhead (and possibly another one coming soon)!!!

Hammerheads are my favorite shark. When you first see one, you wonder why they look like that, then if you're like me, you find out and wonder why more sharks don't look like that. Which I found out today! Thanks Clint!

When you said, "Let's talk about the Elephant in the room", I was prepared to hear about the illustrious Hammerhead Elephant.

I never realized that hammer head sharks heads from the side look like regular shark heads right up untill the eyes that just stick out like its nobody's business

[mowolf]

This channel in combination with the fact that there is a fairly big public aquarium in my city (to which I just got the second season pass in a row) is probably the biggest reason for me to get back into my childhood passion for animals. And I still love so many of them so much! Thank you, Clint!

Gotta say, hammerhead hunting footage is cooler than any other shark hunting footage ive ever seen

34:20: "I would be shocked to discover that this [drag reduction from wing sweep] did not play a role here." Aerospace engineer here. I'm sorry for the shock, but it doesn't play a role here - at least not for the same reasons. The sweep on transonic and supersonic aircraft is there to decrease the effective thickness to chord ratio and decrease the peak pressure coefficient, thereby delaying the onset of localized supersonic flow with the associated shock waves and increased drag. Wing sweep also will help with wave drag at supersonic speeds by minimizing the surface area of normal shocks and increasing the angle of oblique shocks. Compressibility effects and supersonic flow don't really apply to an animal in an incompressible medium at nonlethal speeds.

Heavy wing sweep will allow vortex formation over the leading edge and allow lift to be maintained at very high alpha, but the sweep doesn't look anywhere near aggressive enough for this effect to be at play on this shark. If I had to guess, I would say that the surface is just too darn big and anything to move the center of pressure further aft (such as sweep) has beneficial effects on the longitudinal stability. That surface really wants to make the shark flip up or down and swim backwards which would be mildly inconvenient for the shark.

I don't know why I just watched a 35 minute, mostly talking head documentary about hammerhead sharks. But his enthusiasm was just captivating. Liking and subscribing

[dion]

I'm pretty sure I watched a vid where they explained they're 99% certain that the crazy spiral-jaw on that one prehistoric shark was for ripping nautiloids out of their shells. Mechanically, reproduced the effects with a model and showed that it's perfect for it

[RingR]

I'd give it about al 90% chance that the main reason the hammerheads swim at a 45 degree canted angle is the same reason that owl ears are asymmetric. They swim that way because it allows the sensors on their head to percieve up/down values. The extra lift is probably just a happy accident.

Yes!!!! WE NEED FALSE PENGUIN VIDEO!! 🐧🐧🐧🐧🐧🐧🐧🐧🐧🐧🐧🐧🐧🐧🐧🐧🐧🐧🐧 an icon for each penguin species. Depending on how many you think there are. Anywhere from 16-19...

When I was little (I’m old now), we lived right on the ocean in Florida (Atlantic side) for about 5 years. I remember the fishermen trying to catch some fish in the surf and being utterly disgusted by catching baby(2-3’ long) hammerheads and throwing em back, over and over again. This lasted about 2 weeks every year. I’d go watch them, absolutely fascinated w their weird looks. The beginning of my love for sharks

[annabelle-rlfe]

I’m currently tracking a scalloped hammerhead through Fahlo. She has no idea I exist I love her so much
