Jonathan, a Seychelles giant tortoise, has reached the age of 194 [1], making him the oldest living land animal in the world.
This milestone highlights the extraordinary longevity of certain reptile species and provides a rare biological record of an animal that has outlived multiple human eras. His status as a Guinness World Records Icon underscores the global scientific and public interest in extreme aging.
Jonathan resides on St. Helena, a remote island located in the South Atlantic Ocean [2, 5]. The tortoise is a member of the Seychelles (Aldabra) giant tortoise species [1, 2]. Because of his age, he has become a symbol of endurance and a focal point for those studying the limits of animal lifespans [3, 4].
He reached this age in June 2024 [1, 2, 3]. The recognition from Guinness World Records officially designates him as an Icon, a status reserved for record-holders who have maintained their titles over significant periods of time [3, 4].
Caregivers on the island continue to monitor his health to ensure he remains stable as he continues to age. The environment of St. Helena provides the specific conditions necessary for the tortoise to thrive despite his advanced years [2, 5].
While few details are released regarding his daily medical regimen, his survival to 194 [1] serves as a benchmark for tortoise biology. He remains one of the most famous animals on the planet due to his documented history, and the sheer scale of his longevity [3, 4].

Jonathan's longevity provides critical data for biologists studying senescence and the genetic factors that allow certain species to avoid the typical degradation associated with aging. As a Guinness World Records Icon, he represents the upper limit of known terrestrial longevity, offering a baseline for comparing the health and lifespan of other giant tortoise populations worldwide.
