I'd kinda say Goa Magara is not an elder dragon... yet

think closely, the wing-arms aren't that much of a hint to link him to Elder dragons, i'd go more for my own stamina dragons theory

Dragons can't be exhausted/fatigued, therefore they shouldn't need to eat,

much likely being an elder dragon is kinda like "being a demigod or a god itself", unable to be captured etc...

Since Goa Magara can both be exhauset and captured i'd say it is likely to be an evolution conjunction ring (sorry, i actually translated literally from "anello di congiunzione" in italian... ^^") like Zinogre links mammal monsters and Wyverns (or at least it's inspired to those creatures)

"then why do it become a dragon in adult form"?

First: i don't think it's easy for a goa magara to turn into Shagaru, (considering the numbers of Goa Magaras should be dramatically higher than the numbers of Shagarus, i'd say it's likely to be a mutation/dominant type, like Great Jaggis becoming the "alpha" of their species (despite not living in packs), or more easily explanable, like a Resident Evil Tyrant: 1/5000 becomes a "special-type")

Second: well, a half-wyvern-half dragon ancestor (?) that evolves into something is more likely the dragon part of it takes control over its body features... Elden dragon blood should really do it.

J-just a theory of mine, i really think Goa being just a cute little baby shagaru kinda downgrades it... ^^"
