Great work from Simone Videsen. We found sperm whale slow clicks maintain extreme isochrony with inter-click intervals up to ~10s. That's beyond any known neural system for precise interval timing. May be a long-distance communication system.

In this study, we show that male sperm whales produce low-frequency slow clicks at low repetition rates with extreme source levels > 200 dB re 1 µPa (pp), making them the loudest mammalian communicat...
