Posted by: Parabuteo at Wed Jun 4 22:32:14 2003 [ Email Message ] [ Show All Posts by Parabuteo ] Crotalus unicolor (Aruba Island Rs)is considered by the scientific community in general 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 coloration and overall size enough to warrant a specific status? It seems obvious that the reason why they look a bit different is the isolation from the mainland populations of C. durissus (in this case C.d. cumanensis) I'd appreciate any comments fron the experts.
