Mediterranean Sperm Whales Show Emerging Dialect Differences Between Eastern and Western Populations
By
Michelle Starr
Summary
Scientists have discovered distinct differences in communication styles between eastern and western Mediterranean sperm whale populations. Eastern whales produce faster click patterns (codas) compared to the slower click styles of western whales, suggesting a cultural divide may be emerging. The research, led by bioacoustician Taylor Hersh, indicates these vocal differences could represent the early stages of dialect evolution in these marine mammals.
