Corals rely on tiny hairs to breathe, and several new studies suggest these hairs may malfunction in warming oceans. The research points to a long-overlooked aspect of coral physiology that could be central to the animals' survival as climate change intensifies.

According to the reporting, scientists are now examining how heat stress affects these hairs and what that means for coral health. The findings could reshape understanding of why reefs are dying and which corals might endure.

For businesses tied to reefs—such as tourism, fishing, and coastal protection—the research adds a new layer of risk. If warming waters disable this basic function, coral loss may accelerate faster than previously expected, making climate adaptation more urgent for coastal economies.
