• Priscilla, a 30-year-old Galapagos tortoise, was coaxed onto a board scale with lettuce as penguins queued for keeper Jessica Ray.
• Each weight and measurement was logged in the Zoological Information Management System (ZIMS) to support global comparisons for endangered species.

• Molly the giraffe was expected to be the heaviest at roughly 700 kilos, while the zoo promoted family activities such as its summer Zoo Crew program.
