Are you trying to talk about animals appearing different upon locality? There are a bunch of variation in one species depending on where they come from. I haven't read much up on everywhere that ackies are from, but there sure are plenty of different variants between ackies.
I think I know what you are trying to get at. I think a USCBB Varanus tristis tristis, isn't a pure Vtt(purchased from D. Price). I think some Vto(orientalis) is in that mix. Tristis are very very wide spread, covering much of Australia, so far I've seen plenty of pictures of different localities. There are animals that grow up to have the really dark blacks, and some with more browns, some with grey/purple hues,some that appear that to have more reddish hues. Someone correct me if I'm wrong, but I can only name three different tristis, Vtt, Vto and then Vto(red heads). What ever the mix is, they are still being sold here as Varanus tristis tristis.
I don't think anyone has bred a togian water monitor to cumingi, or a black dragon to a sulfur. Reptile guru has been breeding water monitors lately. The parents are two different types of water monitors. They are just being sold as a water monitor. To some people stating the intergrades or crosses isn't important.
To other it is. I'm trying to go back to some old post now and figure out what type of mix they actually are. bivittatus x marmoratus? To many they appear to be very nice water monitors, some others notice the difference. I recently sold much of my collection, one of Guru's animal was apart of that collection.
