Explore how fish use their gills to breathe, and how these processes make them some of the most efficient breathers on Earth.
--
Recent studies found that elite runners can take in twice as much oxygen as non-runners. And it’s likely that this superhuman ability played a role in breaking the two-hour marathon barrier in 2019. But when it comes to breathing efficiently, not even the best runners can compete with the average fish. What makes fish some of the best breathers on Earth? Dan Kwartler explores the science of gills.

Blobfish don't look like that. Blobfish only look like that when they're brought to the surface and destroyed by the air pressure change. I already knew that quite a few of your videos get stuff wrong, particularly your videos about weight science where you demand weight loss despite that not at all being evidence-based practice, but come on. The pressure difference of the ocean and land is such an important aspect of the topic of this video that you dedicated a whole section of this video to it. And yet you went through the entire animation process with likely multiple quality assurance checks and never realized you animated a pressure-killed fish swimming alive and happy in its natural, correctly-pressured environment??

A lot of aquatic animals like amphibian larvae, sharks, lamprey, and certian bony fish lack an operculum. I'd take a shot and guess that operculums aren't as crucial for underwater breathing if A: the animal is only aquatic temporarily or can substitute air as well, B: they use some other motion to move water through the gills (ram breathing in sharks for instance), or C: they can absorb some oxygen through their skin.

@abhay06976 13 дней назад

if the gills are so effective in pulling the oxygen, why can they not work out of water?

@globin3477 13 дней назад

Some animals actually do have gills that work in the air- land crabs and woodlice, for example. These land gills are so specialized for air that they don't work underwater. In any case, this was answered in the video; Fish rely on the density of water to pull it through the gill covers via pressure differences. This method does not exert enough pressure to pull a continuous stream of air over the gills.

@bhavyapal 14 дней назад

Considering the fact that 21% of air is oxygen but there is only a small amount of oxygen in water , we don't need to be more effective at getting oxygen but fishes have to be

@user-sp8sw7vt5k 13 дней назад

In addition to gills, fish like gouramis and bettas also have an organ called a labyrinth that functions like a lung. I don't know if that's what the lungfish has but labyrinths weren't mentioned by name in the video

@globin3477 13 дней назад

Lungfish are very different from gouramis. Gouramis, like most fish, are ray-finned fish, whereas lungfish are a much smaller group of lobe-finned fish (like coelacanths) that split off a long time ago. (Notably, lungfish are the fish most closely related to tetrapods like amphibians, reptiles, and mammals.) Gouramis also do not use lungs to breathe air; instead, they have a different structure called a labyrinth organ.

@katherineknapp4370 3 дня назад

😊😊😊😊😊

@globin3477 13 дней назад

You forgot to mention that air-breathing isn't unique to lungfish. Lots of fish, both freshwater and saltwater, can do it: For example, Bettas are freshwater fish that can breathe air. Meanwhile, Oceanic Tarpons can also breathe air. Having done a bit of further reading, it seems that most air-breathing fish do not use lungs to breathe air, but instead breathe through their skin like amphibians, or breathe via a labyrinth organ, which seems to be a modified gill arch that is better able to pull oxygen from the air (provided it is wet.)

How do the fish prevent osmosis damage through their gills when they breathe? Sea water is very salty and can pull moisture out of their bloodstream.

@garg4531 13 дней назад

I remember hearing about this in another video. I think it was something along the lines of saltwater fish constantly taking in water and freshwater fish constantly excreting it in order to maintain balance within their respective environments.

@globin3477 13 дней назад

I think a part of it is that saltwater fish's bodies are actually much saltier than our bodies. In fact, I recently recall reading that freshwater fish typically have higher salt levels than the surrounding water. They have various biological salt pumps to maintain this lack of equilibrium. The reason there are no freshwater cephalopods is because cephalopods do not have any sort of salt pump, and would die through some combination of too much moisture in their bloodstream and loosing salt to the environment.

Oxygen gets replenished. I remember hearing multiple times from difference sources that most of the oxygen we breathe comes from the ocean. And creating oxygen tanks is a lot simpler than having to create artificial gills.

So, how did lungs evolve? From gills, or from something else? I ask because my impression that if an animal has evolved bones, and it has also evolved hearing, its hearing has evolved from bones that in earlier species were part of the jaw. But that if an animal has no bones, but has hearing, then its hearing evolved from completely different earlier structures.

@globin3477 13 дней назад

lungs evolved in ancient fish as a way to deal with low oxygen levels in water. In most modern fish, the lung has evolved into a swim bladder, although a few species (most notably lungfish) still retain true lungs.

@globin3477 13 дней назад

I don't think so, unless you somehow surgically connect all those gills to your bloodstream. I don't think any research has been done on such a surgery, nor do I think there will be any work towards this. Even if you somehow managed to pull this off, you would probably find other problems underwater, as your body simply isn't built to deal with those pressures. For instance, I can't imagine it would be pleasant to have lungs completely full of seawater even if you can get oxygen via other means. In fact, that might actually do severe and permanent damage to your lung tissue.

Breathing frequency heavily depends on the size of an animal, so the comparison of how often a human breaths and how often "most fish" breath, really has no meaning. Would have been interesting how often a fish of comparable size breaths.
