Prince Charles and Prince William joined forces in a multilingual video message aimed at saving endangered species like rhinos, tigers and elephants from poachers.

Later this week they will both attend a conference in London on the illegal wildlife trade.

But the campaign came a day after William went on a hunting trip in Spain.
