Gramma, the Oldest Galápagos Tortoise at San Diego Zoo, Has Died at Approximately 141 Years Old

November 20, 2025 — The San Diego Zoo in California has announced the passing of its longest-living resident: a beloved Galápagos tortoise known as Gramma (affectionately called “Grandma” or “Babulia” by visitors). She was estimated to be around 141 years old, making her one of the oldest known tortoises in the world.

The news was first reported by The Independent and later confirmed by the San Diego Zoo Wildlife Alliance.

A Life That Spanned Centuries

Gramma arrived at the San Diego Zoo between 1928 and 1931 from the Bronx Zoo in New York. She was part of the zoo’s very first group of Galápagos tortoises. Over her extraordinary lifetime she witnessed:

• both World Wars,
• the terms of 20 U.S. presidents,
• the transformation of the world from the age of radio to the era of smartphones.

Zookeepers lovingly called her the “Queen of the Zoo.” She was known for her calm, slightly shy personality and her love for romaine lettuce and prickly pear cactus pads.

The Difficult Decision

In her final years, Gramma suffered from severe age-related bone conditions. After careful evaluation, the veterinary team made the compassionate decision to euthanize her to prevent further suffering.

Memories from Visitors

Social media quickly filled with heartfelt tributes. Many people shared childhood photos and stories of meeting the gentle giant.

“When I was 3 or 4 years old, I got to ride on her back — something they no longer allow today. That experience inspired me to get my own desert tortoise and learn everything I could about tortoise conservation,” said 69-year-old Christina Park.

How Long Do Galápagos Tortoises Live?

In the wild, Galápagos tortoises typically live over 100 years. In professional zoological care, with proper diet and veterinary support, they can reach 150 or even longer.

The all-time record holder is Harriet, who lived to approximately 175 years and passed away in Australia Zoo in 2006.

Gramma’s peaceful departure reminds us how fragile even the longest-lived creatures are — and how important it is to protect these magnificent animals for future generations.
