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.
