Common minke whale utilized often and performed by all five whales; it was the principal technique used by M1, M2, and M3 prior to a feeding lunge. An "exhale on the dive" is exactly what its name implies: a whale exhaling as its blowholes submerge. This resulted in a large volume of water being displaced and typically followed a normal blow or a chin-up blow and on occasion a head slap. This technique was only executed by M1 and M5. These new techniques are thought to have been developed by these whales to help them herd small schooling fish (likely capelin) in the
Crab meat and the animal is then returned to the water.
