Communication and Perception
Balaenoptera acutorostrata in the North Atlantic produces an extensive range of sounds. Mellinger and Carson (2000) analyzed pulse trains of minke whales in the Caribbean and classified them into two categories: the “speed-up” trains and the less common “slow-down” trains. Pulse trains are sequences of pulses produced at regular or irregular intervals. There is limited information, however, as to whether this type of vocalization is also present in B. bonaerensis and what function it serves in B. acutorostrata.
