Dec 23, 2018 at 12:27 comment added Keltari Im fairly sure this has been asked before on this site.
Dec 23, 2018 at 9:26 comment added Pelinore The orifice used for taking air into the lungs doesn't have to be the "mouth" in a fictional alien though, it can be entirely separate from the one for eating & doesn't have to have a tongue or vocal chords, just a thought.
Dec 23, 2018 at 9:18 comment added Pelinore If these aliens are relying entirely on oxygen entering their body for respiration there's an absolute size limit on how big they can be, certainly anything the size of a typical human in earths atmosphere that attempts to breath only through it's skin will die, which is why there aren't any, but then, no reality check tag, so your the author, whatever you want I guess :)

Dec 23, 2018 at 4:13 comment added The Square-Cube Law "one of us realised that since they're amphibians they would breathe through their skin, which means they wouldn't have lungs" One of you needs to revise their biology. Amphibians do have lungs.

Dec 23, 2018 at 3:38 comment added John You may want to give them rudimentary lungs anway, large animals can't breath only through the skin, the square cube laws meas they have a much smaller proportional surface area, a human sized animal breathing only through the skin is impossible even if their atmosphere is almost pure oxygen.
