Yeah, that one should be pretty awesome as an adult. I'm debating between a Cuban and a Rhino for my next Cyclura - I hear the Rhinos are the more impressive of the two.
:After speaking with several people with much more experience than I have we've come to the conclusion that this lizard is probably a Caymanensis/Cuban hybrid with emphasis on the Caymanensis. Whatever it is, it's going to be a stunning creature as an adult, but aren't they all? :)
