    This is (fortunately) why there’s a maximum size on insects. The environment is less oxygen rich today than in the eras of giant insects in the past. They reach a size where oxygen can’t penetrate deeply enough onto their bodies.

    Hold on, wait a minute, pause. There are people who think that bugs have lungs?

      To be fair, while bugs and other insects don’t have lungs, some arthropods do. The differences among arthropods, insects and bugs aren’t exactly common knowledge.

            In a nutshell: speaking cladistically, there is no such thing as a fish, or alternatively, all tetrapods are fish. You cant define a monophyletic group that includes “fish” that doesnt also include humans (and all other tetrapods eg birds and such). That’s my understanding anyway

              Fish is a polyphyletic group. It’s a shorthand to refer to various lines of aquatic vertebrates with a similar anatomy. It’s not a clade but that’s not the only way to logically group organisms. People trot it out like a “gotcha” or just misuse it in much the same way they don’t understand speciation (or most science terminology, to be frank)

              We are not fish by anyone’s honest definition, but “there’s no such thing as a fish” is the kind of attention-grabbing false revelation I hate: it’s the headline with none of the understanding to actually learn something.

              (I’m not annoyed at you, I think you understand perfectly based on your wording)

              Can’t we just un-fish it like we do for other clades when we need to?

              “There’s an ape in the office!”

              “Yes, his name is Tom. More importantly, he is a human being, and we don’t refer to them as apes outside of an academic context and even then, only when necessary.”

                  I meant, can’t we just be more specific rather than use paraphyletic grouping?

                  “What’s for dinner?”

                  “Fish”

                  “That could mean anything!”

                  “You know I meant Actinopterygii.”

                  “Still pretty broad.”

                  “Oncorhynchus.”

                  “You know how I feel about trout.”

                  “Ugh. tshawytscha.”

                  “Well, why didn’t you just say so in the first place?”

            We’re all descended from fish.

            Also, IIRC, some fish are more closely related to us than they are to other fish, making it impossible to biologically define a category of animal that includes everything we call a fish but doesn’t include us.

    Why doesn’t the damaging and hot particulate matter in smoke do any harm to or otherwise clog up their spiracles like it does to the inner lining of lungs? I gather lungs are wet and also very delicate, but if they’re directly oxygenating their organs through these spiracles eventually it must get to somewhere wet and delicate for the smoke to get in and potentially harm.

      Maybe something like:

      • The spiracles stop working and the insect stops most major movements
      • When the air becomes better, the new air fills the spiracles and reinvigorates the insect

      vs

      • Humans need to use their muscles to start breathing, or they will require external assistance

      Yup. It simulates a forest fire and encourages them to gorge themselves on honey and leave the hive. They get less protective of the hive (because they think it is doomed) which makes it easier to work. They will check back in under an hour to see if the hive made it, and if so, will regurgitate the honey back and continue on with their day.

          Fun additional bee fact! Bee hives have personalities and each hive has a different one! Some hives are very easy going and have no problems being worked. Other hives don’t like to be touched and will get defensive quickly. When working hives, one of the things you look for is bees lining up on the edge of a frame staring you down. If you see that, hit them with some more smoke else you are about to be stung!

              Bees navigate using the sun. It doesn’t really seem that they make a map, but more seem to know where they are by the process of directions that got them there. When they return to the hive they just reverse the way they got there. If you stand in front of the entrance to a bee hive for a few minutes then turn around to face away from the hive, you will see a swarm of bees flying in a holding pattern waiting for you to move so they can return. Once you move the entrance to the hive gets really busy. They don’t seem to know to go around you, they just wait till the path is clear!

                  Here’s another for the road: mites are a big problem for bees. They latch on to the bees and the bees don’t feel them. One way bee keepers can encourage bees to clean themselves and knock off the mites is by covering the bees in powdered sugar! This makes it look like there are a bunch of powder white bees flying around for a while.
