Giant blue whales dance with the wind to find food

Blue whales (Balaenoptera musculus) are the largest animals on Earth, but despite their large size, scientists still have many unanswered questions about their biology and ecology. A research team of the MBARI's underwater observatory used a directional hydrophone to track the movements of blue whales and learned that these ocean giants respond to changes in the wind to hunt food.

When the winds create an upwelling event, blue whales seek out the plumes of cooler water, where krill are most abundant. When upwelling stops, the whales move offshore into habitat that is transected by shipping lanes, thus putting them in danger.
