A critically endangered sea turtle has completed an extraordinary international rescue mission, arriving at Houston Zoo after a 5,000-mile journey from Wales that involved helicopter transport, transatlantic flight, and collaboration among wildlife organizations on two continents.
Rhossi, a Kemp's ridley sea turtle, reached Texas on August 10 following two years of rehabilitation in the United Kingdom. The turtle now receives treatment from Houston Zoo's veterinary team, which will determine when he can safely return to Gulf of Mexico waters near his native habitat.
The rescue began in December 2023 when a dog discovered the injured turtle on a Welsh beach. At that time, Rhossi weighed only 2 pounds and suffered from cold-stunning caused by dangerously frigid north Atlantic waters. Staff at Anglesey Sea Zoo took custody of the animal and provided intensive care for nearly two years.
During his rehabilitation in Wales, Rhossi gained significant strength and weight. The turtle now weighs 46 pounds, more than tripling his body mass since rescue. Despite this progress, veterinary examinations at Houston Zoo revealed lingering pneumonia in his lungs, requiring continued treatment before release.
Dr. Joe Flanagan, a renowned senior veterinarian, came out of retirement specifically to treat Rhossi. The turtle underwent comprehensive medical evaluation including examination of his organs, eyes, mouth, shell, and flippers, along with x-rays and a CT scan to assess his lung condition.
Zoo veterinary staff report that Rhossi appears healthy, active, and vigorous overall. The team will continue monitoring and treating the turtle to ensure the best possible chance of successful reintroduction to wild Gulf waters.
Kemp's ridley sea turtles represent one of the most endangered species in the world. These animals are native to the Gulf of Mexico but occasionally become swept into powerful ocean currents that carry them thousands of miles across the Atlantic Ocean, explaining how Rhossi ended up so far from home.
The complex international rescue operation required coordination among multiple organizations and individuals. U.S. Fish & Wildlife, NOAA, Anglesey Sea Zoo, Texas State Aquarium, and Welsh helicopter pilot Darren Briggs all contributed to transporting Rhossi across two continents. The journey included a helicopter flight from Wales to London before the transatlantic trip to Houston.
Houston Zoo operates a sea turtle rescue and rehabilitation program supported in part by admission ticket revenue. While Rhossi's return to the Gulf will take longer than initially anticipated due to his pneumonia diagnosis, wildlife officials view his survival as evidence of effective international cooperation in conservation efforts.
The case marks another chapter in ongoing efforts to protect Kemp's ridley sea turtles in Texas waters, where the species has shown signs of recovery in recent years following decades of population decline.
