Just for the record, bullfrogs, Lithobates (Rana) catesbeianus originally hail from the eastern US, northeastern Mexico, and southeastern Canada. They have been introduced to the Southwestern US, where they are reeping havoc. They have also been introduced Argentina, Belgium, Brazil, China, Colombia, Cuba, Dominican Republic, Ecuador, France, Germany, Greece, Haiti, Italy, Jamaica, Japan, Netherlands, Puerto Rico, Taiwan, Uruguay, and Venezuela.

Love the pictures. Triturus marmoratus has been on my want list for some time now.
Thank you for the information I saw some adults this year hen I went to chicago and I was amazed about how big they were... I never imagined something like that..

If you lived in Europe I could probably get you some next year... I have a friend who breeds them (I only have juvies)... But if it makes you feel better, your Bufo alvarius has been on my want list for quite a while too
