From what I remember, JK Rowling didn't know much about snakes. She just wanted scary--giant? Scary. Venomous? Scary! The most detail I remember about Nagini in the book was that she was huge, green, and venomous. It's kind of like she got stories of burmese and vipers mixed and turned it into a super snake of legends. Being the harry potter world, that's acceptable to me because, well, we don't see giants running around either, it isn't a stretch to say there would also be giant venomous maybe magical snakes running around the wizarding world as well, it's not like it's any weirder. Then when I saw the movies I figured "Oh, well, maybe they are trying to sort of base it on reality with a retic pattern but sort of make it different so it's venomous and a different species but they just did a bad job"

But that little quote about Nagini being the snake from the zoo is sort of silly, considering how clear it was stated that this male was born and raised in captivity. I can't imagine Voldemort getting away with using her as a horcrux either lol! I don't know about you, but if a bald freako killed someone and used my captive snake as a horcrux with magic I didn't think was possible, I think I might notice!


And Nagini now will always just make me think of MY boa constrictor!
