A tortoise at Philadelphia Zoo, affectionately named Mommy, has made headlines for becoming the oldest first-time mother of her critically endangered species. The remarkable event saw Mommy welcome 16 hatchlings with her partner, Abrazzo, marking a significant achievement in conservation efforts for Western Santa Cruz Galapagos tortoises.

Mommy has been a resident of the zoo since 1932 and is believed to be nearly 100 years old. Her journey into motherhood took an unexpected turn when she and Abrazzo, who joined the zoo in 2020 as part of a breeding programme, produced their first successful clutch in November 2024 after previous attempts resulted in no viable eggs. This milestone made Mommy the oldest individual of her species to give birth for the first time.
The first four hatchlings, all female, emerged in February 2025 and were joyfully named Blanche, Dorothy, Rose, and Sophia, after the iconic characters from the beloved television show “The Golden Girls.” Following this initial clutch, three male hatchlings were born in the spring, and an additional nine babies arrived over the summer, which included six males and three females.
Zoo officials reported that the successful breeding was the result of a concerted conservation strategy involving the Association of Zoos and Aquariums’ Species Survival Plan. Following the hatching of the tortoises, the population of Western Santa Cruz Galapagos tortoises in managed care increased to 60, a commendable feat considering the species is classified as critically endangered by the International Union for Conservation of Nature (IUCN).
Threats such as habitat loss, invasive species, and human-wildlife conflict have pushed this tortoise species towards the brink of extinction. Nonetheless, the arrival of these hatchlings represents a beacon of hope for their future and highlights the importance of conservation work.
Jo-Elle Mogerman, the president and CEO of Philadelphia Zoo, remarked on the global impact of Mommy’s story. “The story of Mommy, Abrazzo and their now 16 babies has captured the imaginations of people around the world,” she stated. This sentiment underlines the significance of legacy in conservation and the need to protect our planet’s dwindling wildlife.
Lauren Augustine, the zoo’s director of herpetology, expressed pride in the accomplishments of the animal care team, who managed to achieve what was deemed nearly impossible in less than a year. The young tortoises are expected to remain at the zoo for no less than a year before some are relocated to other facilities, aiding in the furtherance of conservation efforts.
As the public continues to show interest in these adorable hatchlings, the zoo remains committed to providing updates on their development and future placements. The naming of the first four females serves as a delightful nod to popular culture while also drawing attention to the broader environmental issues faced by tortoises both in the Galápagos Islands and beyond.
Galapagos tortoises represent a crucial part of the ecosystem on the islands where they reside. They are among the largest living tortoise species, with a lifespan that can extend up to 200 years. The conservation efforts surrounding these tortoises are not only vital for their survival but also for preserving the unique biodiversity characteristic of the Galápagos archipelago.
In reflecting on Mommy’s groundbreaking journey into motherhood, one can appreciate the interconnectedness of wildlife conservation and the impact it has on future generations. The arrival of these hatchlings stands as a reminder of the potential for hope and change in the face of environmental challenges.
