Hi again Gary! Check out Ron & Stella St. Pierre (www.bluetegu.com) there may an "s" added to that web address. Also, agama international. Bert is also very awesome. They will give you a break down and description/demographic info etc. Ron deals in more species than Bert though.
:I have been trying to ascertain the aproximate ranges of tegu species. Argentina and Paraguay are quite well documented, but throughout brazil I have been so far unable to find any reliable information. Does anyone have good information on this? I am primarily looking at T.teguixin, T. merianae and T. rufescens.
