Orcas’ One-Breath Mystery – Marine Biologists Confirm Longstanding Hypothesis

Research shows that killer whales take just one breath between short, shallow dives, with findings aiding in the conservation by estimating their daily fish requirements.
A recent study has verified a longstanding assumption: orcas only breathe once between dives.

The researchers used drone footage and biological data from tags suction-cupped to 11 northern and southern resident killer whales off the coast of B.C. to gather information on the animals’ habits.
