Southern Indian Ocean humpback whales sing different songs

Scientists have found that humpback whales on both sides of the southern Indian Ocean sing different tunes.

The finding is unusual since humpbacks in the same ocean basin usually all sing very similar songs.

The results of the study-conducted by researchers from Wildlife Conservation Society, Columbia University, and Australia -contradict previous humpback whale song comparisons.

Generally, when songs from populations in the same ocean basins are compared, researchers find that the songs contain similar parts or “themes.”

The differences in song between the Indian Ocean humpback populations most likely indicate a limited exchange between the two regions and may shed new light on how whale culture spreads.
