Was this animal in the Philippine crocodile enclosure? It sure looks like a Cuban to me! I ask because I know GPZ lost one of their breeding pair of Philippine Crocs this year.
You're most likely right if you think this is a Cuban - I'm no good with Crocodiles apart from the basics. Come to think about it, I think this one was in the complex while the Philippine crocodile where elsewhere.
Thanks to someone else confirming to me that the Philippine crocodile exhibit was somewhere else than in the complex, it seems now certain that this is a Cuban so I will change the title.
