Marine biologists at the Littoral Acoustic Demonstration Center have discovered that whales seem to to be able to purposely keep their calls from overlapping with the calls of others. Having developed a tool that can identify rhythms in calls and identify individual animals by measuring frequency, pitch and distance, these scientists have found that whales seem to incorporate a type of innate etiquette in their dialogues: they wait until other whales are done calling before starting their own call. However, instead of prioritizing politesse, they are probably doing so in order to be able to clearly hear the calls of others, and such, have realized the efficacy of waiting before calling, which might hint at a greater intelligence than we currently understand.
