specifically this is an Anegada Island Iguana(Cyclura pinguis), wish they would update the signage as it's been almost half a year since the Grand Cayman Blue Iguanas were replaced by the Anegadas.
@King of Komodo Dragons I figured it was *probably* that since I know they have done a lot of behind the scenes breeding and conservation work with them, but was not 100% sure. Thanks for the confirmation, I’ll update the title.
