@The First Guy: "Khezu is not a reptile"? "Just because the game says Wyvern, it doesn't mean it's a reptile"? Are you out of your tree?

Consider this. Rathalos, Nargacuga, Bracchidios, and other reptilian monsters like them are classified as wyverns. Khezu has been named a wyvern, which clearly means that it is related, no matter how distantly, to them. If other wyverns are reptiles, and Khezu is a wyvern, then what else could it be? An arachnid? A fish?

Before you get started on the subject of Bird Wyverns, let me just say two words - Feathered. Dinosaurs. Get my drift?

And as for Pariapuria, it's a wyvern (aka, REPTILE) that has evolved to live similarly to amphibians. Look at it's ecology page here, it'll explain how and why it evolved. A quote: "Pariapuria shares many physical similarites with amphibians".

Thanks to the second guy for answering my first question as well as providing good opinions from past subjects. Now, I need the other four questions answered.
