Archeina - Tumblr Posts
whats up with the 3 slits and feathers on these things, also whats that opening thing you talked about?
the 3 slits are the way the ostomesa respire, i call them pleural lungs they are a form of lungs that the terrestrial ostomesa derived from aquatic ostomesa gills, they inhale hydrogen and exhale diborane
the feather things are their kalriech, which are how they smell and hear, they smell with small olfactory nerve that extends to the end of every thin filament, the structure as a whole is used to hear, with the filaments being hypersensitive, klariech is closer to the fleshy extensions of telluric frog fish than the fur like filaments that cover the rest of their body called archeina
and the glosspharyncal opening is the closable end of their tongue like proboscis
oooo :000 tell us more ab archeina
archeina are the filaments which cover almost every ostomesa, i described them as fur but itd be more accurate to describe them like protofeathers, since they are very diverse between ostomesa, with some having branches in their archeina to absorb sound, others having them as quills similar to telluric porcupines, and so on, unlike fur, pycnofibers, and feathers on earth, the archeina were evolved when every ostomesa was fully aquatic and dependant on the ammonia oceans to survive, and can be found in almost every ostomesa, and the scales on more streamlined aquatic ostomesa are actually similar to the scutes of telluric birds, being supressed archeina, however some oceanic ostomesa [and one fresh ammonia] completely lack archeina being covered in the thick leathery skin all ostomesa have, these ostomesa are very few and far between, being only 3 genera of a very genera rich planet, i hope this helped!!
so... what do "fish" or whatever look like if they all have fur and weird feather ears???????????
well it depends on their niche, if they need to be streamlined and fast, then the ichthyongiu [fish like organisms] will have a single scale where the klariech used to be, being repressed similar to the scutes on telluric birds, and something similar with the archeina being repressed into scales, though if it isn't directly necessary and potentially beneficial they will have it, some even making quills for defense
