Dear Marli,
Yes, this is a nice specimen. It is interesting to note the the size and number of spots in this species varies greatly with longitude (Behrens & Valdes, 2001). At the risk of over generalizing, the number of spots is greater in the northern reaches of it's range.

Best wishes,
Dave Behrens
