wow I can't believe this highly informative video only has 189 views while other videos of sea mammals which aren't nearly as educational have hundreds of thousands
I really enjoyed the way this video was set comparing and contrasting the differences between marine and land mammals and how those adaptations allow for longer dives.
This one of the best informative videos I’ve ever watched. I have always been fascinated by whales and sharks alike. This gives a better understanding of how these creatures evolved to live in such demanding environments.
I always thought whales could hold their breath for so long because they had really big lungs. I never realized they could expand and contract their lungs to be really big and small. Very interesting to learn about their higher hemoglobin and myoglobin levels also.
Good to hear your 5 yr old liked it. My son when 12 showed me how to upload onto UA-cam - I had no idea and needed them up in a hurry for online teaching :)
The evolution of collapsible lungs is something I never knew about. I always assumed whales just had massive lungs, but collapsible lungs help them to exhale carbon dioxide and replenish oxygen much more quickly.
Didn't think I would enjoy learning about adaptations to breath underwater but this video was engaging and easy to follow so I did in fact enjoy it and take a lot away!
I loved studying evolution in high school and the way animals adapt to their surroundings. It's so cool to see the progression of certain traits and features of marine mammals.
I love this video! Always knew that marine mammals have to come up for air but did not expect them to actually have relatively small lungs. Its so cool that they can collaspe their lungs!
I really enjoyed this lecture. This was cool because of what we learned today in class- how the seal can hold its breath for 2.5 hours and then must come up for air.
This video was one of the most enlightening videos because it resolved many myths that I had assumed. Before watching this video I was very confused on how marine mammals breathed and stored air. This was important to learn because now I know that marine mammals do not have larger lungs, and are actually just more efficient at using oxygen.
This was one of my favorite videos because I never actually understood how marine mammals got oxygen from breathing air. This helped me visualize it. I also loved the historical animals that were referenced to highlight the evolutionary transformations.
I loved the animation that demonstrated how marine mammals use their lungs. It helped me understand the concept way better than just reading about it. Also, I had no idea that the water that they blow is actually a mix of warm air from their lungs, mucus, and bacteria from the respiratory system - not seawater!
Whales are a truly incredible species. It is so cool how they can collapse their lungs! I would love to learn more about the respiratory systems of other marine mammals in the future.
I really enjoyed this video. I thought it was fascinating to learn about the placement of blowholes, breathing mechanisms, and haemoglobin content of whale's blood. Super informative and interesting!
Previously, I was not aware of how some marine animals were able to stay underwater for so long, despite having to come to surface for air. I liked that this video answered a lot of the questions I had! It is also interesting to see how the position of the blowhole has changed throughout time.
Thank you for this detailed and extremely clear explanation and especially the fact that you kept the language so simple. Everything about this video was great, I cannot leave out the graphics, props and the camera work 👏
I always wondered why a dolphin's blow hole is at the top of their head and now I know the placement of their nostrils helps them get air quicker when they reach the surface. I also didn't know the hole gradually moves back when the embryo is developing.
It is fascinating how whales have developed over time and have become so efficient at using their lungs, such as exhaling their air 2 to 3 times faster than humans with their nostrils.
Speaking of whales breathing, there was a UA-cam Short of a whale jumping most of its body out of the ocean during a storm. The waves were huge. People commented the whale was having fun during a storm. But I wonder if it had to jump out of water in these huge waves just to be able to get a breath. During calm seas a whale can easily surface for a breath, but is it more difficult as the waves become larger? I don't know.
Amazingly explained, graphics, photos and such a calm soothing voice! I wonder, when whales don't give oxygen to those unnecessary organs, are there any secondary effects? Like do those organs deteriorate faster because they are not receiving oxygen or are them prepared for it? I would assume they are but is fascinating! Thank you for such wonderful video.
I got entirely through medical school without learning the role myoglobin can play in binding oxygen. Probably that's on me a little, but regardless, thank you for this video!
So would say that whales breath when they go to the surface or are they merely capturing oxygen and then carrying it with them underwater and in essence breathing underwater?
This was a great video! I always wondered about marine mammal physiology in terms of breathing mechanisms. I did not know they had more haemoglobin and myoglobin than humans, but that makes a lot of sense. I also thought that the concept of blowhole evolution very interesting, and the parenthesis about fetuses and the development/movement of their blowhole even more so.
That seems stressful needing to venture to the surface every 2 hours just to stay alive. It's like being a scuba diver every day of your life. I'm grateful we don't live like that, then again when that's the only existence you know you just do what you gotta do.
I think there so use to it to survive it’s like second nature to them like us having to drink water to stay hydrated what it’s 8 cups a day we need but it’s fascinating that they store the air in there body’s and select how to use it during a 2 hour time span 😮
This video is amazing: informative, no distracting music, no needless edits, edits that bolstered the dialogue...
I sincerely appreciate the fact that there isn’t background music during the lesson. Thank you.
This video was incredibly easy to follow while giving heaps of relevant information at the same time. Great work!
Thank you for not editing the video with music. Silence makes the presentation perfect.
You're welcome
This was extremely informative. It is always cool to see how a species changes over time, especially how they breathe.
Love this! Never knew the placement of their nostrils evolved.. Also thanks for the gentle delivery, was nice to follow 🙏
Thanks Theanderthal, great to know - whales and dolphins show amazing evolutionary adaptations.
wow I can't believe this highly informative video only has 189 views while other videos of sea mammals which aren't nearly as educational have hundreds of thousands
Gee thanks :)
74k now
Bcs those with more views have more subs, ergo more views
It's called entertainment
189 views?

OMG you're a natural ASMR artist! You're speaking is so soothing!😊

Wish this woman made more video
She is great at teaching
This was amazing. I just watched it with my 5 yr old.... both our minds are blown!
Good to hear your 5 yr old liked it. My son when 12 showed me how to upload onto UA-cam - I had no idea and needed them up in a hurry for online teaching :)
Best video I've watched in a long time! So informative! I learned a lot from this! Thank you!
The flow of this video was great and I was able to follow along and understand the comparisons of whales to humans without a problem
The "flow" was great! (The joke is meh)
ok your exam is next week, be prepared...

It was very cool how you related it back land mammals. But what was fascinating was seeing the evolution of cetaceans through their embryonic stages.
The evolution of the blowhole is incredible. Great vid!

Very accessible video and interesting to watch. I took a lot from it and enjoyed learning about the blowhole!
Thanks Professor Rogers. This is the best video and easiest explanation on dolphin breathing.
this is gold, thank you Tracey!

I had no idea whales could stay underwater for 2+ hours. The placement of the blowholes being so strategic is quite fascinating!
Thank you for this detailed and extremely clear explanation and especially the fact that you kept the language so simple. Everything about this video was great, I cannot leave out the graphics, props and the camera work 👏
this helped me make sense of everything! thank you!
This video was one of my favorite particularly because I love dolphins and whales and have a great interest in evolution!
Absolutely incredible. Thank you for this.
This is a great video. Good facts, well presented, great infographics. No sensationalism. Fabulous
Very precise..keep going... u deserve more subscribers
Thanks a lot for posting. Wonderful both regarding information and presentation 👍🐬🙂
Wow,professor you were amazing explained really well. I understood everything. Thank you.
Thanks Ankita, this is great to know.

Beautifully explained!!!! Thank you!
Thank you Victoria, kind of you to let me know
Thanks Victoria, this is really kind
I liked the comparison with land mammals.
Awesome vid very educational.
Never would’ve thought whales actually blow snot but it makes sense
More informative than my biology class
Amazing job, thanks for the video
These dolphins are exotic and beautiful creatures. It was awesome to see and feel these skeletons during class yesterday.
Very informative! Thanks for posting
Enjoyed this video great delivery
Thankyou for this video! So interesting and informative! Whales are truely fascinating
That was great info!

I watched killer whales documentary and came here. Very informative description. Thanks
Great video. Exactly what I wanted to know and you have a nice speaking voice.
Thanks Jacob for letting me know - very kind

Superbly explained, thanks for sharing this valuable information, maybe Wim Hoff as been studying them for his breathing techniques 👍
I got entirely through medical school without learning the role myoglobin can play in binding oxygen. Probably that's on me a little, but regardless, thank you for this video!
So interesting to learn about the evolution of the blowhole!
Thank you ma’am
Such an information video, thank you
Very very very very very very very very very very superb explanation mam
Great Video!
Great video thanks👍🏻
Amazing! Informative! 💯👍🏼
So would say that whales breath when they go to the surface or are they merely capturing oxygen and then carrying it with them underwater and in essence breathing underwater?
How long dolphins can hold their breath underwater?
Why 305 subs the quality is good
That was awesome thank you
i will remember to take out all of my breath next time im in the pool
great video i love this video😀😀😀😀😀😀😊😊😊😊😊

I love how it’s name is “blow hole” rather than something similar to nostril.
I was today's years old when I found out Whales and Dolphins can’t breath underwater
I wish i can breathe like that while swimming
I always wondered how marine mammals breathe in the water with their blowholes and this video does a great job of explaining it!
Amazing!!!
Sooo... size doesn’t matter?
Nice
so its not about size, its about how you use it. Gotcha
If the blowhole moved to the top of the head as a result of the environment - why did it start on the face?
This video was great an easy to follow. The comparisons of human blood composition to that of whales gave helpful context
Prof. you spelled "breathe" wrong.
oppps... I did too, need to fix, thank you >((((((*> tracey
Why don't the get the bends
good vid, i learned a lot. Please fix the spelling of the word "breathe" in the title... it bothers me :)
Anybody here from Jin and Jimin bickering 😂
why dont you have more subscribers?
I just wonder how they know all this information. Like did they swim around with them and stick a catheter up there stuff lol
Basically Whales got hemoglobin rich Lifestyle !!

ok
Gonna start calling my nose a blowhole now.
Air
So whales evolved from dog looking creatures, to alligator looking creatures, to FISH looking creatures? See this is why I'm skeptical
You underestimate the power of time
