Historic Encounter: Male Humpback Whales Documented in First Same-Sex Copulation Event

Photographers have captured groundbreaking images of a historic event in the world of marine biology – the first documented case of male humpback whales engaging in penetrative sex. This extraordinary discovery was reported by the Pacific Whale Foundation (PWF) researcher, Stephanie Stack, with the images captured by photographers Lyle Krannichfeld and Brandi Romano.

The spectacle unfolded on January 19, 2022, off the picturesque shores of Maui, Hawaii, as Krannichfeld and Romano, working with SWNS Media Group, found themselves in the midst of an unprecedented observation. The males, typically ranging from 12 to 16 meters in length, exhibited behavior that has long intrigued scientists.

As the two photographers observed from a safe distance, they noted a striking contrast between the partners. One whale appeared visibly thin, covered in whale lice, suggesting poor health, while the other, a healthier whale, took a keen interest in its fragile companion. This unique encounter shed light on a private aspect of the majestic marine mammals rarely seen before.

Approaching the photographers’ boat, the stronger whale used its pectoral fins to secure the injured whale, initiating brief penetrations that led to the historical documentation of same-sex behavior in humpback whales. The pair circled the vessel several times, allowing Krannichfeld and Romano to capture the intimate moment from a legal distance as per Hawaii’s regulations.

Upon reviewing the photographs, the marine biologist Stack categorized the whales as both male, marking a significant milestone in cetacean research. This revelation adds a layer of complexity to our understanding of these magnificent creatures, hinting at possible implications of the injured whale’s condition, speculated to be due to a ship strike.

This groundbreaking discovery not only provides valuable insights into the lives of humpback whales but also underscores the importance of continued research and conservation efforts in preserving marine ecosystems. The collaborative efforts of SWNS Media Group, PWF, and dedicated individuals like Krannichfeld and Romano have opened a new chapter in the study of these iconic marine mammals.
