Beneath the surface of the Strait of Hormuz and the surrounding Gulf lies a biological sanctuary. The region is home to around 7,000 dugongs and fewer than 100 Arabian humpback whales"a nonmigratory population that cannot leave these waters. Naval mines, residual military activity, and congested shipping lanes mean the strait remains a high-risk environment"not just for vessels but also for the ecosystems beneath them. Underwater explosions and military sonar don't just scare whales, they can physically blind them, leading to stranding and death. The Arabian humpback whale, unlike its cousins in the Atlantic, does not migrate. For them, the Gulf is not a corridor but home, a permanent habitat. Olivier Adam, a researcher at Sorbonne University Abu Dhabi, says that the Gulf's resident cetaceans"better known as marine mammals"have limited options: Either abandon their habitat or remain and endure prolonged exposure to noise. In the case of Arabian humpback whales, relocation is not realistic, as they are one of the only populations that do not migrate between feeding and breeding areas. "These baleen whales have no way to escape," he says. Whales rely on sound for nearly every essential function: feeding, navigation, reproduction, and social interaction. When that acoustic environment is disrupted, the effects are immediate. In shallow coastal zones, where biodiversity is concentrated, even small disruptions can cascade through the ecosystem.
