The existence of hammerhead sharks implies there exists a nail fish somewhere out there to be discovered.

"Sharks have survived all 5 mass extinctions." - Prime suspects, I would say.

Cutting off shark fins is really one
Of the cruelest things I’ve witnessed done to animals. Sharks are amazing and fascinating animals, and it’s horrible to see them die such an undignified and cruel death just for some shitty soup.

The clip of the fin-less shark being discarded broke my heart. 
Growing up in China I've always been aware of the consumption of shark fins, although now the situation gets better, thinking of still many shark are being tortured like that and thrown into the water alive, sinking in the bottom waiting to die is painful :(
Hope all sharks a bright future although it's probably unlikely :, (

Watching that hammerhead shark drown with its fin cut off was the saddest and infuriating thing I saw this week 😤

I remember watching a documentary where it was stated that in addition to having the sixth sense for detecting electricity that most, if not all sharks have, hammerheads also have a *seventh* sense. It said that hammerheads can detect magnetic fields with great detail in particular, and use the Earth's magnetic field to navigate their migration routes.

Watching that finless shark sink helplessly to the bottom of the ocean, was crushing.

Such a beautiful, complex, and brilliant creature, so heartlessly robbed.

I love this Narrator I’ve been on a binge the past few hours of the Channel and you can tell when someone is actually intelligent and understands what they are saying or not and she clearly does. Keep up the great work!

"The most fearsome predator of the sea, Sharks" ...

The Orca, literally torturing other animals for fun: "Am I a joke to you?"

[Icypenguigo]

That footage of the shark with its fins hacked off sinking to the ocean floor at the end of the video was utterly heartbreaking. Unbelievable that people can be so cruel.

I love channels like this for using technical terms like "Mad Lift" 8:50

It broke my heart to see that shark sink without its fin that was cut off

"And on the tip of all the Hammerheads cephalofoils are their weird, beady eyes."

Hammerhead sharks: "Step in the ocean and say that to my cephalofoil."

[AliHSyed]

The fact about their electrical sensitivity blew me away.. 1.5v of 1500km.. WOW

[HafCoJoe]

Your speech at the end of this video really struck me. It makes me so happy to hear someone able to take their dream and make it a reality! Both your channel and Real Engineering are two of my favorites for interesting and niche technology and science, and I am always excited to see a new video :) THANK YOU for being you and sharing what you care about to the rest of the world.

“The most fearsome predators in the ocean”

Orcas “are we a joke to you”

That footage of the finless shark plummeting to the sea floor was appalling. I'm incredibly glad you showed it, but it's appalling. I'm not outright against the killing of animals, but the combination of outright cruelty and waste is just mind bending. I struggle with how humans can so easily disconnect from certain realities (I struggle with how I see it in myself as well). A fisherman would know that these sharks would still be alive when they're thrown back in, if they just stopped to even think about what they're doing. If they're hellbent on wasting the rest of the shark, just slit the damn thing's throat before you throw it back, you sick fuck

Hammerhead Sharks are such crazy looking animals, so this was a fascinating video! Loved those lazer scans of the heads too. NICE! 🦈

[RobertMarcLehmann]

Awesome work! Love the video! Thank you for what you do!
