About 900 miles off the coast of Chile along the Nazca Ridge, a slew of new discoveries have thrilled marine scientists. During a 28-day expedition, researchers aboard Schmidt Ocean Institute’s vessel Falkor (too) mapped a previously unknown seamount along the ridge’s mountain chain, along with nine others. These included a pristine 800-square-meter coral garden.

The team documented a live Promachoteuthis squid, “a genus that is so rare that only three species have been described based on only a few collected specimens, several of which are from the late 1800s,” a statement about the findings says. “Until now, the squid genus has only been characterized from dead samples found in nets.”

Scientists also recorded the adorable Casper octopus, marking the first time the species has been spotted in the Southern Pacific, and two rare Bathyphysa siphonophores, commonly known as flying spaghetti monsters.
