From July to November each year, the turquoise waters of French Polynesia resonate with the haunting songs of humpback whales (Megaptera novaeangliae). These intricate melodies, often likened to underwater symphonies, captivate scientists, artists, and visitors alike. In 2025, as French Polynesia strengthens its efforts to protect these marine giants, the song of humpback whales remains a mesmerizing phenomenon, blending biology, culture, and ecology.
A Unique Melody in the Animal Kingdom
The song of humpback whales is one of the most sophisticated forms of communication in the animal world. Sung exclusively by males, it consists of repetitive sequences of grunts, moans, wails, and low-frequency notes, organized into “themes” and “phrases” that can last from 10 to 30 minutes. These songs, audible up to 30 kilometers underwater due to sound propagation in the ocean, evolve over time, with each population developing regional variations, much like musical dialects.
In French Polynesia, where humpback whales migrate to breed and calve in warm lagoons, the songs are particularly vibrant during the breeding season from August to November. Males often sing in a “head-down” position, using their natural resonance chamber to amplify their vocalizations. A 2023 study in Royal Society Open Science noted that Polynesian humpback songs share 95% of their structure with other South Pacific populations, indicating significant cultural exchange across vast oceanic distances, as further supported by Roskilde University research in 2024.
An Ecological and Behavioral Role
The humpback whale song plays a crucial role in their reproductive behavior. Scientists believe it primarily serves to attract females and establish dominance among males, though its precise function remains a topic of ongoing research. In 2025, advanced technologies, such as hydrophones deployed by the Mata Tohora association and the Polynesian Directorate of the Environment (DIREN), enable enhanced monitoring of whale songs, providing valuable data on their locations and behaviors.
The songs also contribute to ecological balance. By drawing whales to breeding grounds like Moorea, Tahiti, or Rurutu, they promote genetic diversity. Additionally, humpback whales enrich coral ecosystems by bringing nutrients from deep waters to the surface through their dives, supporting marine biodiversity in Polynesia’s 5-million-square-kilometer marine sanctuary.
A Sensory Experience Like No Other
For visitors to Polynesia in 2025, hearing the song of humpback whales is an unforgettable experience. Certified operators, such as UltraReef, offer trips equipped with hydrophones, allowing real-time listening to the songs. These excursions, capped at six participants per boat, provide a respectful immersion into the whales’ acoustic world, often paired with insights into their biology and cultural significance.
For an optimal experience, consider these tips:
Book early: Quotas for 2025 limit available spots.
Choose certified operators: They ensure compliance with regulations and ethical practices.
Be patient: Songs may not always be audible, but the wait is worthwhile.
Conclusion
The song of humpback whales is more than an acoustic phenomenon—it reflects a complex animal intelligence, a vital ecological role, and a profound cultural heritage in French Polynesia. In 2025, as stricter regulations enhance the protection of these marine giants, visitors have the chance to experience this marine symphony in a more respectful framework. Listening to these melodies fosters a deep connection with the ocean and its inhabitants, serving as a powerful reminder of the need to preserve this natural heritage for future generations.
