Located in the Pacific Ocean 900 miles (1,448 kilometers) off the coast of Chile, the seamount is 1.9 miles (3,109 meters) tall and part of an underwater mountain range that is home to sponge gardens, ancient corals and rare marine species — including a type of squid that was filmed for the first time..

Details of the newly discovered species will be shared with the Ocean Census, an ambitious international collaboration to record marine life hidden in the world’s oceans. It aims to identify 100,000 unknown species in the next 10 years, allowing scientists to better understand and protect the deep-sea ecosystem.
