The turtle, named Nazaré, washed up on a beach in Cumbria in February, showing no signs of movement and covered in algae.

The creature had a successful rehabilitation programme at various Sea Life facilities.

Nazaré was flown to the Azores and released back into the wild earlier this month.

The reptile was rescued from a beach on Walney Island, Barrow-in-Furness, on 4 February.

It was found severely cold-stunned, suffering from pneumonia, and covered with a thick build up of algae and seaweed upon its arrival at Sea Life Blackpool.

Nazaré’s care involved gradually raising its body temperature, hydration injections, and closely monitoring condition around the clock.

The team created floats to make sure Nazaré did not drown, as well as using a toothbrush to clean the turtle’s shell.
