This is the moment 13 Magellanic penguins were released back into the sea on a Brazilian beach. The animals had spent months in rehabilitation after being found weak and stranded during their annual migration. They were given rehydration treatment, nutritional care and physical conditioning before being cleared to return to the ocean. It was the final group to be released this year, bringing the total number of penguins rehabilitated in the season to 38, according to the R3 Animal Association.
