If we can say 'invertebrate', then why can't we say 'non annelid' or 'not mollusk'?
But, nobody is stopping you. ._.
Yeah, I know that. But I was asking why most people use "invertebrate", but no those terms.
because its easier than saying the names of a dozen phyla, when we're trying to ask a short question. "Which invertabrate is the most adorable?" vs "Which gastropod, annelid, hemichordate, chaetognath, peripatid, or - ah frack it, I can't spell the other ones."
But why make a word specifically to distinguish vertebrates from all other animals, and do the same to other animal groups.
because we did. there is no deep reason for it. maybe you'd prefer a return to when half of all the phyla were simply called Vermes (worms) Please don't bring that horrid group up.

It would be quite inefficient for a tiny creature that can easily get all the oxygen it needs through passive diffusion to have a respiratory system that wastes energy on muscles that pump air into sacs. (Hence why lungless salamanders, uniquely miniscule and hyperabundant tetrapods, have ditched their lungs in favor of breathing with their skin and buccal mucous membranes.) But large, active insects already use muscles to pump air in and out of their spiracles, and I don't see why their tracheae couldn't develop pseudo- lungs if other conditions pressured them to grow larger."-HangingTheif

so, instead of using the megafauna to refer to it, you want to use tribes and zoological distrobution?

simply use the name from geological timescale and avoid the question completely.
means just that. I am not sure what is so difficult to understand there. Cretaceous, Paleozoic, Pliocene, Maastrichtian, there we go, nice and simple, no fauna being horribly discriminated against. I also don't get the obsession with things being 'The Age of XYZ', it isn't official in any way. Yes it is subjective, no it doesn't matter that much if someone wants to describe sometime as 'The Age of...' not sure why some people make so much of it. How has this topic deviated so much from talking about big arthropods? true, saying "cretaceous" doesn't discriminate...its also incredably vague - T.rex is temporally closer to humans than to anything in the Jurassic.
and if you ask someone, "what is the Maastrichtian?", most people will give a blank look. if you ask "What is the Cretaceous?", they'll say "the Age of Dinosaurs." (or a part of it)
and you're the one obsessing over "the Age of (insert noun here)"

If we can say 'invertebrate', then why can't we say 'non annelid' or 'not mollusk'?
But, nobody is stopping you. ._.
Yeah, I know that. But I was asking why most people use "invertebrate", but no those terms.
because its easier than saying the names of a dozen phyla, when we're trying to ask a short question. "Which invertabrate is the most adorable?" vs "Which gastropod, annelid, hemichordate, chaetognath, peripatid, or - ah frack it, I can't spell the other ones."
But why make a word specifically to distinguish vertebrates from all other animals Correct me if I'm wrong, but I believe the word "invertebrate" comes from a time when taxonomy wasn't as advanced as it was today, and people thought all "invertebreates" were related. Similar to how we today think all protostomes had one single ancestor and all deuterostomes too. In order to categorize those within their own rank, a word had to be made up. And that word stuck.

Well, now we have protostomes and dueterostomes good luck getting those in school textbooks. and it'll be even less likely to become something most people use in casual conversation.
(and not just because saying "I've got a protostomes problem" sounds like its worse than a rash in the private parts)

Well, we can try. Lets sign a petition. Let's through a coop and take over the government so we can make sure that every single thing about biology is up to date.

But if you want to know the meaning, protostomes is everything closer to arthropods than to chordata. Deuterostomes is everything closer to chordates than arthropods.

Let's be pragmatic with what we call things. Ie, unless you're writing a technical piece for a technical audience call things by what most people will understand.

Time flows like a river. Which is to say, downhill. We can tell this because everything is going downhill rapidly. It would seem prudent to be somewhere else when we reach the sea.

But if you want to know the meaning, protostomes is everything closer to arthropods than to chordata. Deuterostomes is everything closer to chordates than arthropods.
That's not true. Cnidaria and sponges are neither.

Dinosaurs and birds.  Yes, I know cnidarians and sponges are not bilaterans. What's your point? I never said that all animals are bilaterans. But, within bilatera, everything closer to arthropods and mollusks are protostomes, and everything closer to chordates are deuterostomes.

Projects Punga: A terraformed world with no vertebrates Last one crawling: The last arthropod
ARTH-6810: A world without vertebrates (It's ded, but you can still read I guess)
Potential ideas- Swamp world: A world covered in lakes, with the largest being caspian sized. Nematozoic: After a mass extinction of ultimate proportions, a single species of nematode is the only surviving animal. Tri-devonian: A devonian like ecosystem with holocene species on three different continents.
Quotes "Arthropod respiratory systems aren't really "inefficient", they're just better suited to their body size. It would be quite inefficient for a tiny creature that can easily get all the oxygen it needs through passive diffusion to have a respiratory system that wastes energy on muscles that pump air into sacs. (Hence why lungless salamanders, uniquely miniscule and hyperabundant tetrapods, have ditched their lungs in favor of breathing with their skin and buccal mucous membranes.) But large, active insects already use muscles to pump air in and out of their spiracles, and I don't see why their tracheae couldn't develop pseudo- lungs if other conditions pressured them to grow larger."-HangingTheif
"Considering the lifespans of modern non- insect arthropods (decade-old old millipedes, 50 year old tarantulas, 100+ year old lobsters) I wouldn't be surprised if Arthropleura had a lifespan exceeding that of a large testudine"-HangingTheif
"Humans have a tribal mindset and it's not alien for tribes to war on each other. I mean, look at the atrocities chimpanzee tribes do to each other. Most of people's groupings and big conflicts in history are directly or obliquely manifestations of this tribal mindset."-Sceynyos-yis

Except maybe for orthonectida, Dicyemida (Rhombozoa) and Chaetognatha (arrow worms)
I feel that this conversation is now becoming a dead end, each person has its way of calling certain animal groups depending of the context, if someone want to get to something deeper and focused then name specific groups.

"Active" projects
The Future is Far Welcome to the next chapters of the evolution of life on earth, travel the across the earth on a journey that goes beyond the limits, a billion years of future history in the making.
The SE giants project Wonder what is the big of the big on speculative evolution? no problem, here is the answer
Coming one day Age of Mankind Humanity fate and its possible finals.
The Long Cosmic Journey The history outside our world.
The alternative paths The multiverse, the final frontier...
Holocene park: Welcome to the biggest adventure of the last 215 million years, where the age of mammals comes to life again! Cambrian mars: An interesting experiment on an unprecedented scale, the life of a particular and important period in the history of our planet, the cambric life, has been transported to a terraformed and habitable mars in an alternative past. Two different paths, two different worlds, but same life and same weirdness.

Actually, those are protostomes.
