Unique footage of a pilot whale expelling its placenta off the coast of Shetland in 2019 has been revealed for the first time.
The footage, taken by drone operator Nick McCaffrey, shows the animal in the Yell Sound between mainland Shetland and the island of Yell.
Mr McCaffrey did not realise how rare the footage was until he shared it with Emily Hague, a marine mammal researcher at Heriot-Watt University in Edinburgh.
