The Return of the “Giant”: Everest Swims Again in Greek Seas After Two Years of Rehabilitation

08/04/2026

A challenge for the scientific team

The story of 'Everest' began in May 2024 in Preveza, when the sea turtle was found with a severe, intentional head injury. Upon arrival at the Rescue Centre, its condition was critical: malnourished, weighing just 81 kg, and suffering from serious buoyancy problems that made survival in the sea impossible.

The first days of care were especially critical, as the animal was extremely weak and its injury extensive, making the outcome uncertain. The rehabilitation team applied specialised treatment protocols along with individualised care for nearly two years. Repeated diagnostic tests were required, as well as the use of special weights attached to its shell to help it regain balance and dive properly again.

“It was a difficult and demanding case,” explains Eirini Kasimati, Rehabilitation and Animal Welfare officer at ARCHELON. “The size of the animal and its intense stress required delicate handling, but its will to live was remarkable.”

A Return Backed by Impressive Numbers

'Everest', a name given by volunteers because of its imposing size, represents a small scientific achievement. The final measurements before his release were impressive:

Weight: 105 kg (a gain of 24 kg during rehabilitation)
Shell length: 92.7 cm
Rehabilitation duration: 2 years of intensive care

It is one of the largest sea turtles ever rescued at ARCHELON’s Rescue Centre in Glyfada, which has been operating for 32 years and has successfully treated around 1,500 turtles.

The First Release of 2026

On March 30, the long-awaited moment became reality. The “Giant” from Preveza, now bearing a special identification tag, slipped back into the water, creating a deeply emotional moment for the staff and volunteers at the centre.

'Everest’s return to the sea would not have been possible without the support of citizens, both in its rescue and transport, as well as in covering the costs of its care. ARCHELON expressed heartfelt thanks to students and individuals across Greece who “adopted” 'Everest'.

This release, the first of 2026, is a reminder of the urgent need to protect marine life from human-caused harm.
