The thing is Geckos are Lizards but they definitely are not Amphibians. Geckos are a type of Lizards(Squamata). Squares and rectangles, not apples and oranges. And Lizards(Squadmata) are in the Class Reptilia, while Amphibians are in a completely different class, the Class Amphibia.
I think she might be talking about some sort of salamander. Idk what type because I don't go out of my way to learn about them. I don't like amphibians. They freak me the fuck out tbh.
