🪸 Discovery of a 400-year-old giant coral

In the deep waters of Fiordland, New Zealand, divers have made an extraordinary encounter: a black coral whose dimensions surpass everything previously known. This specimen, which reaches a height of 13 feet (4 meters) and a span of 15 feet (4.5 meters), is believed to be between 300 and 400 years old. This discovery, made within protected marine areas, reveals a natural heritage that had remained unknown until now.

Professor James Bell, from Te Herenga Waka—Victoria University of Wellington, shared his enthusiasm. With twenty-five years of experience in marine biology, he states that this is the largest coral he has ever encountered, notably surpassing the usual sizes of 6.5 to 10 feet (two to three meters).


Furthermore, the span of this coral plays a determining role in the species' long-term survival. Black corals grow very slowly, and mature individuals like this one are indispensable for reproduction. By generating more reproductive material, they enable the maintenance of populations over the long term.

To preserve these ancient colonies, a collaboration is underway between the university, the Department of Conservation, and the Fiordland marine reserve. Their project includes mapping protected corals throughout the fjords, to better target areas for preservation. This approach helps guide human activities, such as navigation, and limits the risk of accidental damage.


Contrary to what its name suggests, living black coral appears white in color; only its internal structure is black. It benefits from legal protection under the Wildlife Act, which prohibits any intentional collection or damage.
