This awesome drone footage shows a group of mammal-eating orcas attacking a minke whale in the Avacha Gulf, south-east of Kamchatka. 
The footage, filmed by the Far East Russia Orca Project on June 25, 2017, tracked the group of orcas as they followed the whale until it was fatigued before attacking and eating it. Scientists involved in the project said it was a rare to catch such a hunt as there are only around 200 carnivorous orcas of this type in the Kamchatka region.
