Giant Tortoises at Philadelphia Zoo Celebrate First-Time Parenthood
Historic hatchings of critically endangered species mark a milestone in conservation efforts.
A pair of critically endangered giant tortoises, Abrazzo and Mommy, have achieved a remarkable milestone by becoming first-time parents at the Philadelphia Zoo. At around 100 years old, this dynamic duo has successfully welcomed four hatchlings, marking a historic event in the zoo’s 150-year existence. This achievement is particularly noteworthy as Mommy, who arrived at the zoo in 1932, is now recognized as the oldest known first-time mother of her species.
The Western Santa Cruz Galapagos tortoises face severe threats, with fewer than 50 individuals residing in U.S. zoos. The first egg from the pair hatched on February 27, and following the initial surprise, three more hatchlings quickly followed. Currently, the young tortoises weigh between 70 and 80 grams and are being cared for in the behind-the-scenes areas of the zoo's Reptile and Amphibian House, where they are said to be thriving and growing.
The zoo plans to unveil its adorable hatchlings to the public on April 23, coinciding with the 93rd anniversary of Mommy's arrival at the facility. This breeding initiative is part of the Association of Zoos and Aquariums' program, focused on the survival of endangered species and promoting genetic diversity.
Jo-Elle Mogerman, the zoo’s president and CEO, expressed the significance of this event: “This is a significant milestone in the history of Philadelphia Zoo, and we couldn't be more excited to share this news with our city, region, and the world.” She highlighted the historical connection many visitors may have with Mommy, who has been part of the zoo for nearly a century. Abrazzo joined the zoo more recently, moving to Philadelphia in 2020.
The hope is that in the next century, these hatchlings will contribute to a thriving population of Galapagos tortoises on our planet. As these young tortoises take their first steps in the world, they symbolize hope for sustainable futures and the preservation of endangered species.
