Crotalus unicolor (Aruba Island Rs)is considered by the scientific community as a species of the genus Crotalus, however quite a few herpetologists seem to disagree with this classification, in fact they support the view that Crotalus unicolor is nothing but a subspecies of the neotropical rattlesnake C. durissus. Does anyone know what are the morphological and/or taxonomic differeces in C. unicolor that would in fact place it as a separate species? Are the subtle differences such as color and overall size enough to warrant a specific status? I'd appreciate any comments fron the experts.
Thanks a bunch!
