Very nice! But, penguins at sub 500 meters? Honestly, wtf are you doing down there!?

#42This looks like it might be cool but it's completely unusable for me in Firefox on a 2012 rMBP. It makes the browser nearly unresponsive, taking about 15 seconds to go back to the previous page.

I’m on an iPhone X on Firefox and it’s a very smooth experience.
Re: The Deep Sea
#44I wonder what prevents a fish that goes down to 100 meters from going down to 300 meters or 3000 meters. Does it feel an internal pressure that tells it to not dive further, or is it the amount of light or availability of food it seeks? Since fish wouldn't suffer from decompression sickness, I wonder if they could dive much deeper if they wanted to. Now that I think about it, I've scuba dived to 130 feet and it didn'…
lots and lots of nasty predators

I think this is wrong but I am not a biologist. Fish do not contain air, which is the compressible fluid which limits our ability to go to great depths unprotected. Water is very incompressible, and is most of what fish are. So I don't think depth is the issue. I would hazard a guess that it has to do with where food is.
Fish control their buoyancy via a swim bladder. Suddenly bringing up a deep water fish would make it explode. every 33ft up the volume of air doubles. Hence that rule of diving of never holding your breath and continuously letting the air out as you surface. What I find incredible that a seal could dive that deep, the volume of air at that depth would be a tiny fraction of the volume of air at the surface. It is as i…

I could be missing something, but I don't think this is quite correct.
Coming up from the first 33ft (10 meters) of depth, the pressure would go from two bars to one, or half, so the volume would double.
But any deeper, the ratio of pressure between the current depth and ten meters shallower isn't double, it's n/(n - 1).

Yes the lungs are collapsed completely. A seal, as I understand it, has extremely haemoglobin rich blood and stores all its oxygen there for the dive.
I read that some seals can also force air into respiratory cavities in their skull, which keeps them from suffering decompression sickness.

#47I forgot the number of Jewel squids that I measured. I'm very fond of them, yep.
Re: The Deep Sea
#48Elephant Seals dive to 2400 meters and Cuviers Whales to 3000 meters? That's incredible for a mammal.
Beaked whales in general are fascinating. Only a fraction of a percent of people will likely every see one and only a fraction of those people will even know that they're seeing something more notable than any other whale. They're incredibly poorly understood to the point where there are very possibly species that are completely unknown to science. https://en.wikipedia.org/wiki/Beaked_whale

And I'm in that fraction, muahahahaha. ;-)

Correct, pressure is linear in depth.
