Mommy, who has been a part of the Philadelphia Zoo family for almost 93 years, is setting a precedent as the oldest first-time mother of her species in any zoo worldwide. Alongside her 96-year-old partner, Abrazzo, she now shares the joy of parenting four hatchlings that were born in February 2025. These hatchlings are the first to be produced from Mommy’s eggs, with the possibility of more to come as some are still waiting to hatch. The zoo staff are excited to welcome guests to meet the new additions starting on April 23rd, providing an opportunity to witness this incredible moment in nature.

Abrazzo, the father of the baby tortoises, joined the family in 2020 and has played a crucial role in this unusual reproductive journey. Mommy laid a total of four clutches of eggs over the past two years, culminating in the recent hatching of her offspring. The zookeepers have noted that the baby tortoises currently weigh around 70 to 80 grams, a stark contrast to the fully grown female tortoises of the species that can weigh over 250 pounds. This disparity in size showcases the delicate nature of these young reptiles.

The Philadelphia Zoo is taking special care of the baby tortoises, ensuring their safety and well-being within the Reptile and Amphibian House. These tiny creatures will remain at the zoo for at least five years before any decisions are made about their future. The zoo’s commitment to conservation and preservation of endangered species is highlighted through their involvement in the Association of Zoos and Aquariums Species Survival Plan (SSP). Mommy’s offspring are considered genetically valuable, contributing to the protection and propagation of their species.
Lauren Augustine, the zoo’s director of herpetology and birds, expressed her excitement about this exceptional event, emphasizing the importance of Mommy’s genetic legacy. The Philadelphia Zoo envisions a future where the baby tortoises will form part of a thriving population, ensuring the species’ survival for generations to come. This heartwarming story not only captivates visitors but also serves as a beacon of hope for wildlife conservation efforts worldwide.
The birth of these baby tortoises has sparked awe and admiration among zoo visitors, staff, and animal enthusiasts alike. Mommy’s journey into motherhood at the age of 97 serves as a testament to the resilience and wonder of the animal kingdom. As the hatchlings continue to grow and thrive under the zoo’s care, they represent a symbol of hope for the future of their species. This extraordinary tale of a 97-year-old reptile embracing motherhood for the first time is a testament to the enduring beauty and complexity of nature.
