Hammerhead Sharks: Why Do Their Heads Look Weird?

[@LadyEmilyNyx]

Ahem! Sharks do NOT have torpedo shaped bodies. Sharks came first so torpedos have shark shaped bodies. :P

[@SHARKBYTES]

Respect this comment a lot

[@hedgehog3180]

The word Torpedo was actually originally the name for Electric Rays (hence why the order is still known as Torpediniformes) and was later applied to the naval weapon as a comparison, and then gained wide spread adoption. So technically sharks and torpedos are equally old, it's just the mechanical ones that came later.

[@patkelly8309]

That 92% drop in Aussie Hammerheads is shocking.

[@SHARKBYTES]

It’s a crazy stat

[@simsonyee]

@@SHARKBYTES How come they can't sense the net as an obstacle?

[@DukeRhodes]

They probably assume it's something that wouldn't be that restrictive, something like kelp and believe they can just pass through it.

[@shellydesormier4646]

Thanks Kristian you’re really good at explaining the scientific to the non-very scientific among us. It’s sad to see this species on the decline due to humans. Be well. 🦈

[@SHARKBYTES]

You are more than welcome Shelly, glad you enjoyed the video!

[@Operngeist1]

what I find fascinating from an evolutionary standpoint with hammerheads is that you would assume the ones with the wider heads like wingheads to be the 'newer' species in a sense that the head got wider with time but it's actually the bonnet head that is one of the newer species to evolve if I recall correctly. So their ancestors started out with a wider cephalofoil which then got smaller as the bonnet head evolved. Ben G Thomas has a great video on the evolution of these incredible creatures.

[@SHARKBYTES]

Yes i believe you're correct! Love Ben's video - would love to collab with him someday

[@ReadyMadeLobotomy]

I have a lot of experience dealing with Hammer heads as they tend to love to take ur catch off ur line when shore fishing! at least in Florida lol! So i loved hearing about those crazy creatures! I love them nonetheless. great video

[@romdozer]

There were 2 Hammerheads filmed at the end of last year (via drone) swimming together near Bondi beach where I live, I was so stoked to see it. They were actually on the beach side of the shark nets, so I'm really glad they were able to navigate the nets without getting caught up!

[@ShepherdsCreek]

Good news! Malibu artist is open to collaborations as long as his drone footage isn't shown for legal reasons. An interview or some other fun shark related activity would be awesome to see with you two!

[@SHARKBYTES]

Definite thugs of the ocean

[@Nebulasecura]

My dad went scuba diving in Florida around Miami or Tampa in the mid 2000s, and when he saw a hammerhead in the area he decided to high tail it out of there. It was pretty big and mightve been a great hammerhead.

[@JoeyOutlaw]

It would really be great if you and Hal from Sharks Happen could do a collab! He respects your work and loves your channel and you both really have similar opinions. It would be great if he described the attacks and then you break them down from an educated, scientific perspective. Or if willing even help him with his data he is working on for attacks, population and shark deaths directly related to humans. He is trying to make his data as accurate as possible and not hide or manipulate anything in anyone’s favor. Food for thought.

We've got a collab coming soon - not quite as you describe, but should still be good fun. Keep your eyes peeled!

[@starseeds44]

@SHARKBYTES -- I just wanted to say I LOVE your channel! ❤️ ❤️ ❤️ ❤️ I discovered it a few days ago and have been binge-watching all the episodes. I appreciate that you are a shark scientist and you show both sides when it concerns sharks. 99.9% of the time shark attacks are not predatory and other factors are involved. A very small percentage are actual predatory attacks but it's very rare when you consider how many millions of people are in the oceans every day. Sharks are to be respected and feared. I also appreciate that you call out Ocean Ramsey and other people who touch sharks and try to ride sharks. Sharks are not toys to be played with. They're wild animals who should be respected and kept at a distance. People that do things like that are only causing more problems for sharks in the long run. It makes me so mad when that kind of thing happens. People that do something like that, record it and post it online are doing it for their own benefit only. They're trying to get views, go viral and make money. If they truly respected sharks they wouldn't do that. Much respect to you for pointing that out! I think your Channel is really going to get huge this year. I love your videos! You're a lot of fun to watch but you're also interesting and we learn a lot from your videos. I hope you have a wonderful 2023! 🙂😀

[@katemarz2521]

Long time viewer, first time commenter! Love the hammerhead video -so fascinating. My question: some hammerhead species school In huge numbers - is there any evidence as to why they do this?

[@SHARKBYTES]

Thanks so much for commenting for the first time Kate, it really helps out the channel when people comment! In regard to your question, I believe it’s thought that hammerheads school in huge numbers due to their social nature. Some marine biologists have speculated it’s to protect themselves from the opposite sex (lone females might be bombarded with pesky males). It might also be to rest during the day in a safe environment, before they split off at night to hunt on their own!

[@katemarz2521]

@@SHARKBYTES Thanks so much for replying! I love the idea of sharks just hanging out together because they enjoy socialising, and that there may be other benefits for them too.

The exact video i asked for already exists ! So sick man. Im not sure if this is true but i heard another added feature of eye placement is that it also allows for a greater degree of area to be scanned with vision when swinging their heads side to side , making it easier to find prey. I heard you mention the head swinging for electric impulse detection but would this also help with visually finding prey ? Thanks so much the stoke is real watching this stuff. Sharks are so cool something so mystical about them.

[@SHARKBYTES]

I'm sure the yawing process must expand the degree's at which they can see for sure

[@Shrock568]

The hammerhead with the smallest cephalofiol is the only one that is an omnivore. So it wouldn’t need the predatory vision as much as the other species.

[@PaxmanY3J]

I saw a Hammerhead from the beach in Gran Canaria last June, Perfectly framed in a wave just before it broke. I few other people also saw it and scarpered out of the water fairly quickly, I was in about waist deep. As it was only about a meter long and the only thing I did know (*thought I Knew) about Hammerheads is they were an open water species I figured it was just a lost juvenile and stayed where I was hoping for another glimpse. Well after seeing the clips in this vieo maybe I should have scarpered to lol, (yes I do know Hammeheads get a bad rep and rarely bite humans unlike the vicious Oblada that savagely nibbled me in Lanzerote last week)

[@WaterShowsProd]

Clearly I've had a lifelong affinity for hammerhead sharks, as I chose one for my company logo, a logo I originally designed when I was in primary school. However, I never knew about the aid to manoeuverability the cepholafoil provided. I always assumed that wider heads also gave them more accuracy pinponting prey hidden in the sand.

[@Nmethyltransferase]

Watch and react to Seaspiracy.

[@TH3BUSHWOOKI3]

There’s another thing, you could associate the wider wing with better long distance vision vs the smaller wing having better depth perception giving them the edge in more up close and personal encounters
