    A buddy of mine made a video of diving to find Greenland Sharks. It's apparently not terribly easy to find them. https://www.youtube.com/watch?v=8kS89k6DjnM

      A lot of deep sea creatures have very slow metabolisms. It is one of the many reasons sea dredging and mining should be held with such disdain: these are ecosystems which may take thousands of years to recover.

      We don't even appreciate how long it takes a forest to recover, much less one with glass sponges that are thousands of years old.

        Don't forget about forests that are thousands of years old too, very contemporary serious long-term damage

        When H Melville stuffed the middle of Moby Dick with a "cetology" -- BEFORE The Origin of Species, famously saying "a whale is a fish" -- he didn't forget the Greenland Shark. I think all the time about how many of those sharks swimming around in 1851 are still swimming around today.

          Note that Melville was well aware of the reasons that "whales aren't fish", and went over those in detail, then said he was going to call them fish anyway.

            The whale=fish thing is also an old joke about catholics. Back when one could not eat meat on fridays, all sorts of water-living mamals were declared to be "fish" for purposes of eating. So a new world protestant author in the 1800s is pointing a finger at oldworld religion and science.

              I think that's perfectly fair. The same way everyone knows that chimps are monkeys, it's just brainy losers who insist they're just apes

              • mikkupikku 3 hours ago

                Yes I agree. All the moreso because the word fish is very ancient and was used to mean any aquatic animal long before Linnaeus came along and decided to "well ackshully" the word.

          There's a business lesson in the longest lived creatures being the ones that move slow, abide small insults, and make themselves generally unappetizing.

          Oh, the article is by Katherine Rundell. She has written some very nice children's books.

            The Greenland shark appears, if I remember correctly, in her book "Golden Mole", which is about many interesting creatures. This is published as Vanishing Treasures in some countries. Her "Super-Infinite: The Transformations of John Donne" is interesting and also not a children's book.

            Jeremy Wade, host of the TV show "River Monsters", has an episode where he investigates the Loch Ness Monster and concludes it's likely a Greenland Shark that swam up an underground river from the North Atlantic to the lake. He likens the shark's horse-like face and the distribution of the low fins on the shark's back to descriptions of the monster. A solitary long-living fish could explain the occasional sightings, and the scientists' findings that there is not enough food in the lake for a breeding population of large carnivores.

              As a sibling comment notes most sharks cannot live long in freshwater, and moreover this is soecifically true of Greenland sharks, though they do sometimes spend time in brackish river mouth environments, so, unless it developed the weird behavior of migrating quickly up the relevant underground river to make a quick appearance and then inmediately rushing back down the river to the ocean, that’s one answer we can be fairly certain is wrong.

              There are a few sharks that can live in freshwater, but they tend to inhabit warmer oceans.f_

                Totally wild factoid: Bull sharks have been caught in tributaries of the Mississippi River in Illinois. (Back before they built all the dams)

                • dragonwriter 4 hours ago

                  Yeah, bull sharks are the most common and wide-ranging of the sharks that are adapted to survive in a wide range of salinity levels.

                  • darkteflon 1 hour ago

                    Bull sharks are often found in rivers tens of kilometres from the ocean in Queensland.

                      That's the kind of rare and highly luck based curiosity they ought to give you a plaque for. "From this shore in 1973 local angler..." Slap it on the same sign post as the flood high water markers they put up.

                      That's too bad. I thought he was on to something.

                    • RajT88 7 hours ago

                      He is likely wrong (most sharks cannot live long in fresh water). But given the show, he has to conclude it is a fish of some sort, and it is not going to be 10k arctic char in a dinosaur suit.

                      • ljlolel 7 hours ago

                        Doubt a shark could survive in freshwater. They’re very tuned to salinity

                        • mikkupikku 5 hours ago

                          Bull sharks can, but they're the famous exception to this. Sometimes they swim up a river and nip somebody.

                          The most likely explanation for the Loch Ness Monster, of course, is that it's entirely made up and didn't require an actual sighting or a real physical phenomenon, ever, to trigger people's imaginations.

                          I think the title is a reference to David Foster Wallace's awesome article, Consider the Lobster.
