Scientists Discover Golden Coral Too Unique for Any Family

Scientists exploring underwater mountains off Costa Rica have discovered a coral so unusual that it required the creation of a completely new family in the tree of life.

The bright yellow coral grows like a glowing tree on the deep ocean floor, with some colonies reaching over a meter tall. Researchers found it between 360 and 529 meters below the surface during expeditions in 2019 and 2023.

The coral stands out against a stunning backdrop. Rocky outcrops where it thrives are covered almost entirely with brittle stars, creating the appearance of shimmering fields beneath the golden branches.

That magical scene inspired its scientific name, Laurinque elenya. The genus comes from "Laurinquë," meaning "golden tree" in the Elvish language J.R.R. Tolkien created for The Lord of the Rings. The species name elenya means "of the stars," referring to the brittle star populations surrounding each colony.

Dr. Odalisca Breedy of the Universidad de Costa Rica led the research team. When she first saw the coral garden in 2019, she thought it might belong to a known species but quickly realized something was different.

The real surprise came from genetic testing. Scientists initially used three standard genes to classify the coral, but each gene pointed toward a completely different family. The contradictory results were so unusual that researchers turned to phylogenomics, comparing hundreds of genes simultaneously.

The broader analysis revealed something remarkable. This coral doesn't belong to any previously recognized family but represents a distinct evolutionary lineage. Scientists created a new family called Laurinqueidae to accommodate it.

The Ripple Effect

This discovery highlights how much we still don't know about our own planet. The deep ocean covers roughly two-thirds of Earth's surface, yet it remains less explored than the surface of Mars.

Coral gardens like this one do more than look beautiful. Their complex, branching structures provide essential habitat for countless other deep-sea creatures, making them biodiversity hotspots in one of Earth's least understood environments.

The find joins a growing list of undocumented species being discovered on Costa Rica's seamounts. Each expedition brings new surprises, suggesting that thousands of species may still be waiting to be found in the deep.

The remotely operated vehicle SuBastian collected specimens during expeditions aboard research vessels Falkor and Falkor (too), operated by the Schmidt Ocean Institute. These advanced tools allow scientists to explore depths that were impossible to reach just decades ago.

Every golden branch of Laurinque elenya is a reminder that our planet still holds wonder in its deepest places.
