Blue Whale Behavior and Communication

The video explores the sounds of the ocean, focusing on blue whale calls in the eastern North Pacific. It describes two primary types of calls: the rhythmic A call and the low-frequency B call. Using a Critter Cam, researchers study blue whale behavior off the California coast, revealing deep dives and interactions with other whales. The footage suggests that whale calls may be more about companionship than feeding, providing new insights into these majestic creatures.
