Is there any sure signs ( besides looking at the color ) that will tell a rossalini from a quadrivittata, if we assume that its not a intergrade !?

Regards Martin.

( Sorry about bad English )

Rossalleni will have a red tongue. If the tongue is black there is probably some yellow rat in there recently.

Aaah, thank you Matt....that is a smart ( and easy ) way when trying to determin the sub spec
So black or Red/orange tounge would be one of the difference between the 2 sub spec...

I have also heard if a yellow rat has any Glades rat in it it's eyes are more likely to be orange and not grayish yellow. Jeff

I agree somewhat but you can have yellows with red/orange eyes in just about any part of their range.

I have Love Line Everglades rats and Hypo Everglades rats and I have produce quite a few over the years. The red vs. black tongue is not really valid from what I have seen. There have been a handful over the years that have had black on the tongues and when I lived in Florida I found more than a few yellow rats well outside of glades territory with red tongues. It is more prevelent in the glades to have the red tongue but not a cut and dry marker of pure. I have also seen many different animals listed as everglades that clearly are not so the best bet is to buy from breeders who take pride in their stock and I am more than likely not producing any this year so this is not a sales pitch for me.

It also depends on what animals you are trying to seperate. Are you looking at wild animals or CB animals at a store or in an ad??

.........agree about not being good or perfect for ID

have seen screaming orange rats , glades I would say, but they had half red and some black on the tongue....

and that top pic screams.........gotta get me some of them, I assume hypo ....nice.........

Well in the end I guess it is impossibly to tell for 100% sure, but then the best we can do, I think, is to try to produce offsprings that looks as close to "the standart sub spec look" as possibly whitout knowing if we can be sure that the spec we are working whit really is a 100% sub spec pure..

Basically, there is no 100% accurate way to tell a Yellow from a Glades. Also, the validity of rossalleni as a true subspecies is highly debatable, as are all sspp. in Pantherophis obsoletus (or even sspp. in general, BTW). The way I see it, "purity" in a highly introgressive species like Pantherophis obsoletus can only be linked to locality. Until about a year ago I owned a beautiful pair of tomato red Glades, as true as it gets, but with black tongues. So I guess that doesn't work either.
