First Underwater Footage Of Rare Type D Orca

Friday, 2 March

For the first time, a rare variety of orca known as Type D has been filmed underwater. Tour vessel passengers returning to South America from an Antarctic voyage last December got a surprise. A pod of unusual orcas, or killer whales, surfaced.
