Well Jo, I hop I can help you......I have been on that website you posted before, several times in fact, and my snakes were sold to me as Leucy Texas rat snakes, and they do have a bluish tint to their eyes, and my female Definately has the unpredicatable attitude that I hear Texas rats have, so I'm guessing I have some cage tag changing to do for my two (tag posted on cage says L. obsoleta obsoleta),but I guess I'll be changing that. The species look almost identical,so indentification for may be difficult unless you have both species side by side to compare.... and the heads on my guys heads are pointier than the regular leucy black rat snake. Unfortunately, i have also hear of integrades between the two species and seen babies labeled as Leucistic Texas Black Rat snakes.....how confusing!!!!!! All I know, is that about 3 and a half years ago I saw a picture in a snake book of a pure white snake with blue eyes and I had to have it...I ended up getting a pair for my birthday!!! So, what ever species (or poss. integrated species) I have, all I know is i got what I wanted...and I loove my LRS, LTS, LTBRS, LBS, whatever ya call dem white snakes wit purty eyes!!!
