    This video is amazing: informative, no distracting music, no needless edits, edits that bolstered the dialogue...

    This was extremely informative. It is always cool to see how a species changes over time, especially how they breathe.

    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.

    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.

  • @lihuing4686

    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.

  • @averywall7938
    @averywall7938 5 років тому

    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.

  • @sweetlife149
    @sweetlife149 6 років тому

    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.

  • @TheSDKMusic
    @TheSDKMusic 6 років тому +2

    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.

  • @emilychaffee7123
    @emilychaffee7123 5 років тому

    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!

  • @lauracharos8626

    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.

  • @KidCurry-kx8bv

    @rebeccagoetz3913 5 років тому

    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.

    @dbx1233 7 місяців тому

    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.

  • @davewelbylivinginhistinyti4796

    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.
