One of the planet’s most capable apex predators, orca whales can take on great white sharks all by themselves, attack boats, and have tight matrilineal family bonds. Now, a new study combined tagging data, physiology, drone footage, and statistical analysis to confirm a long-held assumption. Orcas take only one breath between their dives. The findings are described in a study published May 15 in the journal PLOS ONE and could have some important conservation implications.
This data is used in tandem with drone footage taken by drone pilot Keith Holmes and the Hakai Institute. McRae could study this drone footage and assess what behaviors the whales were doing and count the number of breaths they were taking during different behaviors. https://youtu.be/A5A9fnhUevs “The drone footage is very captivating to watch, but the challenging part for scientists is going from a few clips of video to meaningful numbers and data analysis,” says Volpov.
