    Whales suffocate to death; they don’t drown.

    Human breathing is controlled by the autonomic nervous system. We have to hold our breath on purpose to stop ourselves from automatically breathing. This makes us passive breathers. Whales, however, are active breathers. They must choose to inhale which is why they can sleep without sucking in air. When they get too old, sick, or weak to surface, they suffocate.

    Bonus fact: whales can’t breathe through their mouths; it goes straight to the stomach. The blowhole is the only respiratory tract.

    Bonus bonus: a blue whale’s throat is so small it could choke to death on a grapefruit.

      Bonus bonus: a blue whale’s throat is so small it could choke to death on a grapefruit.

      I’m sure their throat can be blocked that way; but if they can’t breathe through their mouth anyway, is it actually choking? Or just terminally blocked?

        Fair point. I didn’t even consider the ramifications of wording it like that instead of just saying it has a small throat. I tend to use analogies a lot

          Nah, it makes sense, and ice heard this phrasing before - just always wondered if they meant the poor whale couldn’t breathe, or basically just had indigestion!

    The Blue Whale is so large, that if you laid one out on a standard NBA basketball court, the game would be postponed.

    Earth’s atmosphere is an ocean of gas. The ocean is an atmosphere of liquid. Words are made up.

    When a whale dies and its corpse falls to the bottom of the ocean, entire ecosystems rapidly develop around eating every part of it due to how scarce resources are in the deep ocean. This phenomenon is called a “whale fall” and it’s a major source of energy for deep ocean ecosystems.

      Sometimes I wonder if a shipping container full of billionaires would have a similar effect.

        That seems like a waste of a perfectly good shipping container.

        Why don’t we just use environmentally friendly hemp ropes and locally sourced boulders?

          Locally sourcing boulders over the Marianas Trench is going to be such a pain. I’m pretty sure the environmental benefits will outweigh importing some nice basalt from Hawaii before we leave out.

    There are lakes in the ocean called brine lakes/pools. Brine is essentially concentrated saltwater; its high salinity means it’s denser than water. On rare occasions, brine doesn’t mix enough with the existing saltwater around it, sinking to the bottom of the ocean and forming these lakes. The lake itself is usually devoid of life; brine itself is so salty that animals go into toxic shock if exposed for too long. However, the edges usually are full of life, where usually things like mussels and other extremophile organisms thrive.

    Side note, subnautica’s lost river is based off of this. No big leviathans in real life though, at least none observed yet…

      Wow, I had no idea these were a thing… and it’s so funky how the surface of the brine pool interacts with the surrounding seawater!

        It was never stated but I always assumed the “goo” referred to industrial waste. But SpongeBob creator Steve Hillenburg was an actual marine biologist and would have been well aware of brine pools, so that’s probably right.

          Brine can be from industrial waste

          Technically, brine just means a high concentration of salt in a fluid. It doesn’t necessarily have to be sodium chloride like we know, it can be other salts, like calcium chloride. Though the most common case for industrial brine is just desalination plants, other industries can still create brine, like mining/oil drilling. It also depends on how it’s released. Large amounts dumped at once is the reason for manmade brine pools.

    Greenland sharks are pretty amazing

    They can grow up to 24 feet putting them at the same giant scale as great whites and basking sharks, but most are usually closer to 5 meters long

    They can live for hundreds of years due to extremely slow metabolism and ambush feeding, some individuals found around 400 years old are as old as the Jamestown colony, Don Quixote, and the discovery of logarithms.

    They are opportunistic feeders and have been found with polar bear and reindeer in their digestive systems, and can pull/vacuum in water to catch their primary prey of fish, eels, and other sharks.

      Back to the horrors of the deep…

      They also commonly have eye parasites that severely impairs their vision or blinds them called Ommatokoita elongata.

      So they get to live long with multiple generations of parasites stuck in their eyes they can’t get out.

      Be me

      young shark, ready to make my mark on the world

      Find a book falling from the sky called Don Quixote

      eh_mid.jpg

      Ignore humans for a few hundred years, eat some fish instead

      Find out it’s become a core component of their identity and everyone knows about it

      Even had a ballet about it

      wtf

        Don Quixote is actually an awesome book, you should definitely read or listen to it. Give it a bit to get rolling, and you will absolutely be doubled over with laughter

      So 5 meter long sharks with 24 feet? That sounds terrifying. How far up the beach can they run?

      Are they the ones where you have to ferment the flesh or it is toxic? Or wasn’t that a shark?
