After numerous and constant reports over more than 100 days, the “tortugo Jorge no longer has satellite monitoring”. This was reported by the authorities of Mendoza, where he lived in captivity for 38 years, rehabilitated and prepared to return to the ocean.
The system had “allowed to follow step by step the journey” of the specimen in the Atlantic and now it is already part of its habitat without tracking. The story is already a regional example.
**The tortugo Jorge no longer has satellite monitoring**
This outcome of his story, recorded on **July 29 with the last transmission of the SPOT-6 satellite device**, is expected in this type of monitoring, as stated. **It does not represent any negative indication about the health or behavior of the animal**.
**Jorge traveled between 3500 and 4000 kilometers in open sea**. He moved from his release point to the warm waters of Brazil, in a migratory trajectory considered typical for an adult male of his species.
“His orientation ability, appropriate behavior, and adaptation to the natural environment consolidate this experience as **a true milestone in marine conservation**,” said the authorities.
“The City of Mendoza celebrates the success of this process, reaffirming its commitment to environmental care, animal welfare, and science applied to sustainable development,” they added.
**Why did monitoring stop?**
Since his **release on April 11, 2025**, **Jorge was monitored via satellite for 109 days**. This allowed for a precise record of his behavior at sea, his movements, and stay in feeding areas.
**The device stopped emitting a signal after entering Guanabara Bay**, on July 29 at 00:58.
According to specialists, the **transmission cut is common** in this type of experience due to factors such as **battery exhaustion**, the accumulation of marine organisms on the equipment (biofouling), or sensor wear. **In no case does it imply a negative signal about his condition**.
“The monitoring of Jorge **not only achieved its objective but greatly exceeded expectations**,” they said. “It provided unprecedented information about the marine movements of a male green turtle, a stage that is poorly documented. Unlike females, males do not return to land to nest,” they stated.
His **migratory route**, his displacement speed, and his rapid arrival at the **Brazilian coast** in just 18 days attest to his optimal health, orientation ability, and readaptation to wildlife.
Dr. Mariela Dassis, a biologist and member of the CONICET team that led the monitoring, explained that “Jorge managed to orient himself, move towards warm waters, and show expected patterns. Everything indicates that he made a typical migration for his species. His **reintegration was a real success**”.
“We knew that the transmitter could stop emitting at any time,” she added. “The information we obtained in these more than 100 days is of enormous scientific value and reinforces the importance of investing in these processes,” Dassis said.
**Jorge’s story**
Jorge spent over 38 years in captivity. **His release was possible after nearly three years of clinical preparation, training, and environmental simulations**. Additionally, an intense interdisciplinary work involving biologists, veterinarians, scientific institutions, NGOs, and the City of Mendoza.
This made the acquisition of the satellite tracker possible and accompanied the entire process. This milestone, which captured the attention and affection of thousands of people, demonstrates that **collaboration between science, public management, and citizen commitment can achieve exceptional results**.
“The City of Mendoza deeply appreciates the interest of the entire community and reiterates its commitment to continue working for **wildlife welfare and environmental care**,” they expressed.
