Hi, I am 802kup (Real name, Hanna Joy Fechik) and I have recentley gotten into this anime!
So I have observed the life and body forms of the Keronians, Maronians, and Axolotls and decided I would create realistic depictions of them!
This is the family: Amphireptosapiono I made this up. I guess these are just three of that class of extra terrestrial life!
Other examples of this alien family are.......... (made most of these up)
Waninians: Crocodilians: Crocodile, alligator, and caiman
Kameminians: Turtles and Tortises
Ashinians (Traditional: Ashinashiimorians) caecilians
Chikyu Doragonians: Earth dragons
Tochi no takageians: land Lizards
Hebibians: Snakes (Not to be confused with the other aliens called Vipers)
Lastly the 3 we know well in this series...........
Keronians: frogs and toads
Maronians: sea lizards
PS: I used google translate to look up the Japanese words for all real reptile and amphibian known and put a few more letters describing what extra terrestrial reptilian or amphibious being they are.
EX. Wani (Crocodilia)
Herpotology: Study of the two ectotherms we call reptiles and amphibians!
