WIRED reported on Sunday that the microscopic hairs corals rely on to breathe may stop functioning correctly as ocean temperatures climb. The finding points to a warming-related threat to a basic biological process in corals, according to the outlet.
The hairs in question are tiny structures on coral tissue that support gas exchange — the process by which the animals take in what they need and release what they do not. WIRED describes them as helping corals breathe. Under warming conditions, that function may break down, the outlet reports.
The report does not specify which coral species were studied, where the work was carried out, or which researchers conducted it. It also does not give figures for the temperatures at which the hairs begin to malfunction. Those details were not included in the material available.
The coverage adds to a broader body of reporting on how rising ocean temperatures affect reef-building corals. Corals are already known to be sensitive to heat, and warming seas have been linked to stress events on reefs worldwide. The WIRED report focuses on a less visible mechanism: the small surface structures involved in respiration, rather than the large-scale bleaching events that usually draw attention.

Because the summary provides only the headline finding, the scope of the underlying research remains unclear. It is not known from the available material whether the work was based on laboratory experiments, field observations, or both, nor whether the effect was observed across multiple species or a single one.
What to watch next: whether the researchers publish full details on which corals are affected and at what temperatures the hairs begin to fail.
