A scientific study led by experts in bioacoustics and marine biology from the University of Bristol and the University of St Andrews in the United Kingdom has concluded that a cultural and linguistic split is emerging among sperm whale communities living in the Mediterranean Sea.
The study, published in the journal Nature and reported by Erm News, found that researchers observed a clear difference in communication patterns and vocal clicks (coded signals) between whales residing in the eastern Mediterranean and those in the western part.
According to the analyses, eastern whales produce rapid, successive vocal clicks, while western whales employ a significantly slower acoustic pattern — indicating the emergence of local cultural development within these marine communities.
