That's the problem with common names. They get mis-used and some of them are just made up by the supplier at the time.
Tell them you want the exact species name not a common name.
If you don't really know what it is you can't properly care for it.

Hmm. I've never heard of that species either. Maybe get a pic of it and we can help determine what it might be.

i may have just heard it wrong to I didnt really hear her at first but she lives so far away and I dont have her number but im goin there on friday

I am not certain about the laws where you live, but here in MA the petstores are required by law to list the animals latin (official) name with the animal.

As mentioned, many petstores rename animals to suit their needs or to dictate coloration, etc. The latin name however allows the potential owner the ability to research the animal properly and to find out its "true" name.

That's a very large monitor when it reaches adulthood. 6 ft +

Oh, Yeah, Black throats are beautiful as babies. At least the ones I've seen. If you get one you might as well name him "Jethro"! It will need A LOT of food! (Remember the "Beverly Hillbillies"?)
