If you could have any reptile or amphibian in the world what would if be?

Draco volans, though IIRC they don't do well in captivity. Bummer because I'd build up a floor to ceiling enclosure for them in a long room.

I like those too.

I couldn't possibly narrow it down to just one species.
But, here are a few of my personal dream herps that, for one reason or another, I have never owned:
- Marbled newt
- Alpine newt
- Surinam toad
- Yellow-spotted River Turtle
- Borneo River turtle
- Radiated tortoise
- Blotched Blue Tongue skink
- Northern White lipped python
- Green Cat snake

I'd better just stop there.

That's a cool list I want the blotched BTS also.

im surprised no one else has said tuatara beside the OP. i would definitely want that.

Borneo earless monitor trio and a trio of shingleback skinks would be high on my list of things I'd like to be able to keep.

Not necessarily in this particular order: 1) C.B. Varanus komodoensis, C.B. (I believe that is impossible, but, feel free to correct me) Conraua goliath (I know this is technically an amphibian, but still...I <3 them) and a C.B. Sphenodon punctatus punctatus.

Nobody said this list had to be realistic, correct!

This list keeps getting better!

I would own and would like to try breeding Indigo snakes.

As long as we are going to list things like Komodo Dragons and Tuataras and other unrealistic things I'll go with a velociraptor. If we need to keep it living I'd go with the Chinese giant salamander as well although I don't really like that orange one at all.

On the more realistic side Centralian Blue tongues (might as well be unrealistic for me) , Naultinus elegans, caiman lizards, green tree monitors, Masobe geckos. All things I could have had in the past (except for the skinks) but I just can't justify spending the money. I'd also love a group of monkey tail skinks.

Oh, and Corroboree frogs. and molochs...and...
