Memory Alpha is quite helpful when learning about all the background actors on Star Trek, even including all of the cats that played Spot on The Next Generation. However, I can't seem to find the animal actor that played the lizard version of Data's cat Spot in the episode "Genesis." Are there any production notes that state which animal actor was chosen to play the role of Spot? What kind of iguana was it (assuming it was an iguana)?
I had the opportunity to speak recently to Rob Bloch of Critters of the Cinema (who provided this green iguana, as well as various other animals seen in this and other seasons of TNG) and I am advised that its name was Willie.
