Most invertebrates have no internal air sac breathing organ. Arachnids kinda do, and I’m seeing something about semi-aquatic snails, but direct diffusion is pretty efficient at that scale.
Axolotls have them despite not needing them because they can live just fine without ever inhaling air for their entire life. But they sometimes do it for fun and then blow out bubbles.
And, for the most part, humans’ lungs don’t have bees!
I somehow forgot about bees not having lungs. I knew some other small things didn’t.
Speak for yourself
I find that hard to beelieve
I’m skeptical too, but that’s the buzz.
What’s that? Human lungs don’t have bees?!
A large influx of bees ought to put a stop to that!

Amphibians are the weirdest vertebrates.
Looking at my axolotl that is currently trying to pretend to be a plant, yep.
