Scientists exploring seamounts off the coast of Costa Rica have discovered a new coral so genetically and morphologically distinct that it required the creation of an entirely new family for its classification. Bright yellow and tree-like, the coral was found growing some 360 to 529 metres beneath the surface of the Pacific. The discovery is described in the open-access journal ZooKeys.
The colonies, which can grow to over a metre tall, were collected using the remotely operated vehicle SuBastian aboard the research vessels Falkor and Falkor (too), operated by the Schmidt Ocean Institute, during expeditions to the seamounts off Isla del Coco and the Costa Rican Pacific margin in 2019 and 2023.
Researchers found the coral thriving in large numbers on rocky outcrops that were almost entirely blanketed by brittle stars, creating a shimmering, star-strewn seafloor from which the golden coral branches rose like glowing trees.
That image inspired the coral’s name. The new genus, Laurinque, comes from "Laurinquë", meaning “golden tree” in Quenya, the Elvish language devised by J.R.R. Tolkien for The Lord of the Rings and The Silmarillion, chosen in reference to the colonies’ bright yellow, tree-like form.
