A critically endangered sea turtle that washed up on a Welsh beach has been flown 5,000 miles back towards its natural home after spending more than two years in specialist care.Rhossi, a Kemp's ridley sea turtle, was found close to death by a local dog on Traeth Llydan in Anglesey in December 2023.Just 25 centimetres long and weighing less than a kilogram, the cold-stunned turtle was taken to Anglesey Sea Zoo, where he underwent an intensive rehabilitation programme.Now, after more than two years of care, Rhossi has safely completed the first leg of his extraordinary journey back to the Gulf of Mexico.He travelled by helicopter from Anglesey to Heathrow before boarding a cargo flight bound for Houston, spending around 18 hours in transit, including a ten-hour flight in the aircraft's hold.To help protect his skin and prevent dehydration during the long journey, conservationists applied Vaseline and KY Jelly to his body and eyes.Frankie Hobro, owner and director of Anglesey Sea Zoo, has accompanied Rhossi throughout the operation, describing the trip as the culmination of years of work.She said: 'We've had to slather Rhossi in KY jelly and vaseline to try and stop him from dehydrating - which is always quite an amusing one going to buy that at the chemist!

When they reach the colder waters around northern Europe during winter, they can become cold-stunned and wash ashore.For Rhossi, however, the hope is that his remarkable journey will soon end where it began: in the warm waters of the Gulf of Mexico, surrounded by other members of one of the world's rarest turtle species.You can help donate to Rhossi's journey costs here.
