If you got to experience Galapagos Islands with us, you know that a giant tortoise is just hitting its prime when it becomes middle aged…. And this lady right here shows us all that it’s never too late!
Your next thing might not be having babies, but whatever it is, do it!

A nearly 100-year-old tortoise has become a first-time mother, and her 16 hatchlings are now part of a major conservation milestone.
At the Philadelphia Zoo, a Western Santa Cruz Galápagos tortoise named Mommy has produced offspring for the first time after living at the zoo since 1932. She was paired with Abrazzo, another nearly century-old tortoise who arrived in 2020 through the Association of Zoos and Aquariums Species Survival Plan.
The result is 16 hatchlings, nine males and seven females, born in 2025 inside the zoo’s Reptile and Amphibian House. The zoo says this is the first successful hatching of this species in its more than 150-year history, and Mommy is considered the oldest first-time mother of her species in a U.S. zoo.
Western Santa Cruz Galápagos tortoises are listed as critically endangered by the International Union for Conservation of Nature. Their wild relatives live in the Galápagos Islands off Ecuador, where threats include habitat loss, invasive species, and human-wildlife conflict.
Mommy’s genetic line had not previously been represented in the AZA breeding population, making these hatchlings especially important for maintaining genetic diversity among managed populations. Including the new babies, the managed AZA population of Western Santa Cruz Galápagos tortoises is now reported at 60 individuals.
Galápagos tortoises are among the largest living tortoises, and scientists estimate they can live 100 to 200 years. For conservation educators, this kind of long-lived species offers a powerful way to teach about patience, stewardship, and the long timelines involved in protecting vulnerable animals.
What lessons do you think stories like Mommy’s can offer about conservation across generations?
