Spotting

Hard to tell for sure, but it's probably a Sand Goanna (Varanus gouldii) or a Yellow-spotted Monitor (Varanus panotpes), Although it's a bit out of the panoptes natural range. If it's captive though it could be that.

this particular one is however we had a small one living on our property for almost 2 years grew alot in that time but the only photos i have of the wild one are very blurry ,thats why i posted this one in stead alot clearer to id.

If this is captive this may take longer since it may not be native. Do you know if it is?
