The photos and videos were taken using a camera strapped to a custom-built hexacopter named Moblyare. The footage features of a family group of Northern Resident killer whales of British Columbia swimming in the brisk turquoise waters off the coast of Canada. The filmed group included a two-year-old calf and a young-of-the-year.
The purpose of the project wasn't simply to capture cute closeups, but to better understand a population that's considered endangered. Scientists wanted to know if these regional orcas are getting enough to eat. Some are, some aren't.
