Researchers Uncover Hundreds of New Marine Species in the Underwater Mountain Ecosystems of the Pacific Ocean

Stretching thousands of miles off Chile’s coast to Rapa Nui, also known as Easter Island, the Salas y Gómez Ridge is a vast underwater mountain range in the Pacific Ocean. Seventy-three percent of the region is part of the high seas, which is under international control and vastly underexplored. The Salas y Gómez Ridge is one of the most biologically productive regions in the world, and thanks to researchers with the Schmidt Ocean Institute, we now know more about the life that thrives there.
During a recent 40-day expedition, an international team of scientists discovered that the area is home to 160 species not known to live in the region, 50 of which are thought to be entirely new to researchers. The team primarily studied 10 of the approximately 110 seamounts near the western edge of the ridge closest to Rapa Nui. This expedition follows a similar trip in January to the Nazca Ridge, which connects to the Salas y Gómez Ridge, that revealed approximately 100 new species.
Images gathered from remote-operated vehicles highlight the regions’ wild diversity, spotlighting mollusks, sea stars, glass sponges, sea urchins, and crabs, some of which hadn’t been seen previously. Included are the bright right, spiny Chaunacops that’s part of the sea toad family, the scarcely seen whiplash squid, and a spiky squat lobster hiding among coral.
Because of the findings, the area is under consideration for protected status, although only Chile and Palau have ratified the U.N. treaty to do so. The measure requires 60 countries to formally adopt the agreement.

An international group of scientists aboard a recent Schmidt Ocean Institute expedition believe they have discovered more than 100 new species living on seamounts off the coast of Chile, including deep-sea corals, glass sponges, sea urchins, amphipods, and squat lobsters.
