That's an interesting discovery.

How does an animal as large and ferocious-looking as the great white shark successfully attack its prey without detection?

According to TheGuardian, the fearsome animals use the ocean’s darkness and depth to their advantage.

Scientists in Guadalupe used an undersea drone to document the first great white predatory behavior filmed from beneath the water’s surface. They shot 13 hours of footage, which supported the idea that the great whites dive deep to use light to their advantage. They hover low above the sand, staying in the shadows until they detect and lunge toward other marine creatures swimming above. The findings were recently published in the Journal of Fish Biology.

“If the shark hangs down at a great depth, in the darkness, then its prey swims above it silhouetted and the shark reduces its own likelihood of detection,” Greg Skomal, a biologist and lead author on the study, told The Guardian. “The remarkable new observations indicate that [my colleagues’] hypothesis is correct, and the sharks ambush from the darkness.”

The sharks also displayed some surprising behavior in the form of attacks on the drone, which they saw as potential prey. You can see the fish gnawing on the machinery in the video above from Woods Hole Oceanographic Institution, and learn more about the scientists' research over at The Guardian’s website.

Thanks Cap'n Poker for sharing this one.   I do a fair amount of UW photography, but haven't thought about an armor-plated case for my drone... cool!

That's interesting...

Good one !

Very Interesting - Thanks

Nice bass!

Nice watch

Glad you enjoyed this. Yes, a shark proof housing. Haha

They would make lunch out of it... ;-)
I hope you succeed.

I thought as much myself. It's certainly not your everyday story.


Looking for something new and interesting to share with you, fairly frequently. ;-)

Always on the hunt, for something to bring a thought or broad smile.

I was wondering if anyone might share my thoughts on this?

Good to have your input this morning. Thanks.

Now someone needs to FPV the shark if they haven't already so we can see that video.  Cool video.

Yes, another one of them stories that appeal to us...

Haha, yeah, a shark cam, would be awesome....

I'm sure it's already been done, someplace . ;-)

Pretty cool!  I've been playing around with building a small underwater RPV.  This got me thinking that if I make it small enough, I could get some FPV imagery going into the shark's stomach after it swallowed my RPV!

Yes, but once they bite down, the video will likely abruptly end...  ;-)

It would be a real trip, travelling through the intestinal tract though. Good plan.
Hope to see it through its fruition.

That's a great idea, but don't forget to add some LED's...

I'm a huge fan of Shark Week.

In the last couple of years,  they've had shows where a cam was temporarily attached to a shark -- great whites!!!

Footage when they recovered the cams was very, very cool and entertaining.

Wouldn't it be a treat to swim with the great whites? Snickers

Yes, we could feed them too... Ha
Better to stay home, dry, on the sofa...

This video absolutely changed my plan to buy a shark pet.

Well you know, if kept in a smaller environment, they don't grow into large killer predators.

Like having pet piranha. They don't eat your fingers. Haha

But yes, if given enough space, they will transform...

Hey A, sweet, you enjoyed it too. Yes, it's another one of those interesting investigations that find unexpected results. I still cringe when I see how these sharks can extend their inner mouth, giving a much larger area of teeth and JAWS. To grab and destroy their prey animals. ;-)

Please post any super interesting finds of your own.
Thanks for your participation on the forum.
