Sumatran Water monitors and which subspecies are the largest and smallest?
 

I have 2 Sumatran water monitors about 18-22 inches, one is much larger which I am very sure is a male. When I first got them as hatchlings they were the same size but now the one looks like he could swallow the other lol. Also the one that is larger would always move his head like he was ready to mate even though he was months old, weird.

The water monitors sold as Sumatrans are they Varanus Salvator, Salvator, and do they actually really come from Sumatra or do they all come from Sri Lanka? So which of these subspecies is the largest and smallest, most common ect?

I love monitors and tegus, and water monitors are up there on my list with how intelligent they are. Please feel free to tell me your knowlegde and or interesting stories you have had with these wonderful lizards.

Thanks in advance.

I think Sri Lankan are known to be the largest. Technically Sumatrans are now varanus salvator macromaculatus too, not varanus salvator salvator. Idk man, to be honest unless an animal was bought from a renowned breeder or imported it's a tough call to say if they are true sumatrans. A lot of people slap 'Sumatrans on water monitors too if they don't actually know the local or subspecies. It sucks :(

Btw I see it is a dead post but this i see a lot of questions on varanus salvator subspecies and not a lot of answers so I hope this helps someone! NERD and quolibet are good resources for these.
