Why is the blue Whale larger than most Dinosaur, yet it lives in a lower oxygen content world, and spends a large part of it's life holding it's breath?

Higher oxygen content, is the reason given to explain larger size.
But the blue whale (most whales) accomplishes this in a lower oxygen system, and they breathe less?

I'm not sure if this question has been definitively answered yet. You would probably start by figuring out how exactly holding your breath for periods of time effects growth.

There is the obvious part where more oxygen means more energy for more growth. But there are surely many subtleties along the way.

>>9524416
If you really want an answer it's a few things. Whales have the advantages of being adapted to land (strong muscle support and bones to support those muscles) but also reap the benefits of being underwater (gravity doesn't impact them as much due to buoyancy) and that second part is why you have the ability to grow so large.

Not only do they have large bones and muscles but they have less restraint on body size because it doesn't carry as much energy to be large as it would above ground.

The purpose of breathing is to get an electron acceptor to maintain an ion gradient within the mitochondria to produce more energy through the breakdown of NADH and FADH2 formed during the Krebs cycle. I guess that having more oxygen allows larger animals because more energy can be made and thus more cells can be maintained? If this is the case, then the blue whale may just require less energy than the dinosaurs -implying a lower metabolism or less expended energy. This makes some sense given that less energy needs to be used in a whale compared to a dinosaur because it doesn't need to to say- stand upright, as it lives underwater.

This is just a theory, however.

Or at least, that an animal that size that is not designed to support its weight on land cannot support its weight on land. Larger sauropods show that an animal approaching that size can do so, if evolved to do so. There is no particular reason to assume that the largest sauropods found to date represent either the largest sauropods that ever existed, not that the largest sauropods were as large as it is possible for a land animal to become.

[Anonymous No.9526236]

Sauropods used many bird technologies to allow them to be bigger than most other dinosaurs, such as hollow bones and air sack lungs. If we assume they were the only ones with bird technology, and the other big dinosaurs did not, then the difference in size between mammals and dinosaurs other than sauropods is not as great, although still pretty big.
When you compare the size of land mammals to dinosaurs, it's a mistake to only consider mammals living in the present, when a large number of big mammals were killed by humans a few 10s of thousand years ago, and dinosaurs did not have to deal with humans.
Still though.
Another reason for the greater size in dinosaurs is that they laid eggs, which allows them to get rid of their children faster. Big mammals are stuck with their children for years which makes reproduction slow.

In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level effective gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh about 0.5% more at the poles than at the Equator.

Sauropods and other dinos had access to large amounts of energy that only they could consume. Animals in the regions you named have to compete over recourses with many other species. Species that live in the north often have larger sizes because lack of competition means more energy. Polar bears can afford to be the largest land predators because they have a near monopoly on seals. Spermwhales can afford being fuckhuge by being the only mammals that can access deep sea squid.

Natural selection favors size + enough energy to sustain large size = larger size.
The sauropods experienced evolutionary pressure to grow larger and had the energy to do so. I don't know how they did it, but i know the answer isn't oxygen. Firstly the more mass an animal has, the LESS it requires energy (and thus oxygen) to maintain an unit of mass. Secondly increasing the oxygen percentage of the air you breathe has very little effect on performance, the limiting factor there is how fast you can pump blood through your lungs.

Sauropods were not big because of "lower oxygen content" in the atmosphere of Mesozoic earth, in fact during the Mesozoic there was less oxygen than today, it was during the carboniferous period that oxygen content was very high which led arthopods to grow to larger sizes, Dinosaurs were capable of growing to larger sizes because of certain anatomical features allowed them to grow to those sizes for example the weight estimates in that picture are incorrect and based on earlier estimates from yesteryear it is now believed that large dinosaurs like sauropods may have weigh significantly less because for example they had fewer muscles in their necks and tails and that they may have had boyant gas filled organs that mitigated some of their weight as well.

[Anonymous No.9543635]

because less energy is required to live in/under water and food is much more available, just open the gigantic mouth and continue lazily cosating underwater and food itself just swims into the stomach, that also explain its higher mass, not sure about the metabolic rates of whales but I guess they are a lot slower than of most mammals on land

That's not really true, but it's environment has the same density as it does, so it takes less energy to move the huge mass. It still has to maintain a huge number of cells though and overcome a huge amount of inertia + water drag (hence it's hilarious low top speed both sprint and marathon). What's way more interesting is that it doesn't get cancer once a week despite it's huge number of cells. Maybe it's cells just reproduce way less.

Jellyfish resembling the solar system is a nice analogy but a mere coincidence. The hydrodynamics and feeding mechanism of the jellyfish dictate its shape, not gravity within the actual jellfish
That said, the density of water means you can have those tendrils suspended and floating around, which would just not work on land.
Cnidarians like jellies do not have a skeleton because their strat is to float around or slowly swim around and maybe mindlessly bump into some prey whereas sessile cnidarians like coral actually build carbonate shells and form colonies from the ground up.
In short, floating things are the density of whatever they're floating in and can expand out in any direction, whereas benthic things or things that sit on the surface are denser than the water or air they are in, and are more affected by gravity.

Solar System is shaped like on orb the inner disc surrounded by the Oort Cloud. The Solar System bounces up and down every 30 million years as it travels around the Galaxy.
