A harbour seal wearing a satellite linked transmitter on its head waits to be released into the waters of Howe Sound in Porteau Cove, British Columbia November 20, 2013. The seal is one of two which had received months of care at the Vancouver Aquarium Marine Mammal Rescue Centre after being rescued from the wild. Wearing the transmitters will help track their movements after their release. REUTERS/Andy Clark (CANADA - Tags: SOCIETY ANIMALS)
