Rescued penguins and sea lion return to the Atlantic

More than 60 penguins and a sea lion rescued last year off the Brazilian coast are released back into the wild.
Stranded or lost during their four-year long migration, they were brought back to strength at a rehabilitation centre for marine animals in Ubatuba, 230km (140 miles) from Sao Paulo.
Now it is hoped they will catch the current to take them back home.
