well i got in contact with the people at deerfarms. It seems that these pics are an optical illusion. 11-13" is max size and they cost around 2k in the states.....
uros are awesome to look at, but terrible to care for since they have terrible tempers and aren't very handle-able. If you've had other lizards, you know. If not, be careful!!
Ive herd that some are really nippy but most are calm and chilled out lizards specialy as cb. U. tomasi really dont know but they tend to be aparently on the delicate side, not begginer uro
