Communication and Perception
The dominant form of communication involves various audible whistles. Whistling remains simple during periods of rest. However, the intricacy of the whistles increases during times of excitement, as well as when the pod is in the process of killing prey. Complex whistles are also heard while the pod is eating and when traveling speeds are high. This indicates that such activities require a greater amount of coordination in the pod. Sounds are also used in echolocation, allowing these whales to orient themselves in space.
Communication Channels: acoustic
