The Titanic lies 12,500 feet below the surface of the ocean. Cuvier’s beaked whales have been recorded reaching depths of over 10,000 feet! They did it by holding their breath for over three hours. I’ve personally held my breath for about one minute and dove to a depth of around 30 feet. That is nothing compared to the current freediving world record holder, Herbert Nitsch, who held his breath for four minutes while diving to a depth of 214 metres. Unfortunately, he suffered from severe decompression sickness and required extensive rehabilitation just to walk again.
Sperm whales dive to about 3,280 feet where they feed on giant squid and octopus. Elephant seals mostly feed on benthic fish, like skates and rays, that live on the ocean floor. So these seals will dive up 5,000 feet in search of food!
How do marine mammals survive these depths? At just 200 meters under water, or 650 feet, the pressure would pop a champagne cork INTO the bottle. At around 6,200 feet or 1,900 meters, if you punctured a scuba tank, water would rush IN instead of air rushing out.
For one. The resting position of their nostrils is closed. The same is true for a whale’s blowhole. They have to flex in order to take a breath. This is simply to prevent water from getting into their lungs.
Elephant seals, sperm whales, and cuvier’s beaked whales actually breathe OUT before their dives so that their lungs are empty. And their ribs are loosely articulated and JOINTED so that they collapse under the immense pressure of the deep ocean.
All this to say that, unlike humans, these marine mammals are almost perfectly evolved to dive to extreme depths. And they do it for a very good reason. Food.

Hahahaha yay!!! Thank you!
Thank you for this video. Really. Informative. Keep them coming!!!
I will as long as you keep watching!
Cuvier's beaked whale to her children: Hey kids, want to see the newest attraction at the Titanic wreck?
come on, there would be clowns and gaming consoles
I didn't hear the plane. (hehe.) I really admire your humility and awe when it comes to knowledge. There's an old saying: "You can never step in the same river twice." And that's especially true about what we know. There's always something new to learn.
The natural, rest position of their noses is closed! That's amazing. Evolution is such a remarkable process. It's hard to stay mindful of it, because we have such short lives. Thank you for another enjoyable learning experience.
My favorite thing about science is how much we don’t know!!
@@KPassionate That's my favorite thing too. I remember my first day in physics class, or the first time I began learning about any new thing. Such joy! A whole new world available to me.
I love that you are trying to build a new rescue center. I volunteer at the Clearwater Marine Aquarium in Florida where our motto is Rescue, Rehab, Release and it’s awesome!!
Hit it out of the park again, KP & Double! YIKES...The part about how much we have not explored is really interesting. And rather unsettling too...No, didn't hear the plane.
Hahaha thanks! Glad the plane wasn’t disruptive.
Mother nature never ceases to amaze me.
I live in the Desert and it can be bone dry and blistering hot for months and months sometimes it seems like years. Yet somehow when it rains these little desert toads pop up. How the heck those things can survive the heat and dry blows my mind.
I'm less amazed at how long the Cuvier Whales can hold their breath, and more freaked out that they can get down to 3000m without being compressed to the diameter of a paper towel tube!
I have to admit that since we cannot explore as deep as these animals, I can only imagine the fabulous new things they get to see. Just unreal!!!
Just one day it would be cool to be a whale!
@@KPassionate Would be awesome!!!!
With how dark it is below, I doubt they “see” fabulous new things
Whales are amazing~👍
Thank you for sharing this video~🤗
Yes they are!
Woah, the Oregon coast aquarium! I am born and raised in Corvallis Oregon and have gone to the Oregon coast aquarium in Newport/waldport my entire life. I saw kaiko the orca. I love the otters. I also love the marine science center right next to the aquarium. I love crabbing, exploring the Oregon coast. Yachats/cape perpetua/Garibaldi/Astoria/Pacific city/depo bay, Oregon are some of my favorite coastal places.
Couldn't hear the plane when you first asked but near the end you could hear it.
Hahaha thanks!!
now I know! thanks
Thanks for watching!
Could hear the plain as it approached distinctly even though the background music covered it at the beginning when you asked for the plane and whether we could hear it. 😊
slight plane noise. i had to listen.
Hahaha nice!
Yes no plane until 10 seconds before it ends
Perfect 😂
No plane sound until 6:20.
Thank you for educating us.
Teeth cracking, ugh. Gives me the shivers!
No plane sounds during the video but toward the end definitely plane sound. ^_^;
Thanks for letting me know!
You're welcome.
Honestly, if you hadn't pointed it out, it would have just been white noise. ^_^ But, thanks for clearing that up.
Finally heard the plane at 6:11, barely.
12.500ft = 3810m
10.000ft = 3048m
SALUTATIONS FOR ALL FIGHTERS ✋✌🎩
Seeing you are a marine biologist and this vid touches on whales, perhaps you can answer me this: I've seen multiple videos with divers next to sperm whales and a lot of times, the whales open their mouthes / drop their lower jaws.
In body language, I perceive nothing threatening in this motion, so I wonder: are they moving their loer w to get a clearer echo picture of the divers?
Opening and closing the jaw can still be a threat display. Usually cetaceans will do this to indicate they would like you to keep a good distance away. Great question!
@@KPassionate Thank you for your swift reply.
So seeing you state this applies to all cetaceans , am I right to think that it also applies to Orcas and smaller dolphins?
@@Lord_RFAS yep! It’s called jaw stretching or clapping
Have any Whales been seen in the location of the Titanic site
They come close, as I mention in the video.
Sorry I clicked the link to the old video 😂
Ugh. How bad was it?
@@KPassionate you made a lot of improvements along these years! But the content of that old video was really interesting and fun to watch! 👏👏👏
@@Playerestblog well thank you!
First comment. Plz pin! Thank you ❤❤
I would guess NO. LOL
Super close though!
@@KPassionate Oh WOW !
Are you attempting reverse psychology? If you don't want people to click on your frst video, then remove it.
I can’t remove it because it’s getting tons of views right now. But it is an awful video
@KPassionate Ah, well, that makes sense. Since I have your attention, I'd like to ask a question. How do whales know their limits? How do they know when enough is enough and that diving much further might kill them?
Hmmm good question. I imagine it becomes more and more painful the closer to their limits that they go. Pain is such a useful tool for animals. It tells us when to stop and what not to do! Positive punishment by nature!
@@KPassionate That makes sense. Thank you for the interaction. Keep up the good work. 👍🏻
Have any Whales been seen in the location of the Titanic what whale species are in that location I was reading an article a few days ago and people think because of these killer whale attacks on the yards people think it was killer whales attack the submersible that went missing is some people think it was a giant squid or a sperm while that attacked submersible as a marine biologist is it possible that are giant squid could have been responsible but I know submersible imploted could a giant squid or a sperm whale attack attack it or not
I don’t think anyone actually believes killer whales sank the titan submersible. That is just click bait and has zero supporting evidence
Do you support the idea that was a giant squid or a sperm whale could have accidentally hit the Titan Forestter a wildlife biologist fence it could have been a sperm whale or a giant squid that accidentally hit the Titan do you think it's possible it could have been one of those two
@@scottwalker5379 nope. Just a crappy submersible that imploded predictably
Oh ok I just thought someone said it was a sperm whale that bumped into the submersible or a giant squid attacked it
As a marine biologist why don't you support the theory killer whales sunk the Titan and you never answer my question has Whales ever been seen in the Titanic site
