Challenger deep goodreads6/24/2023 ![]() ![]() ![]() The team also found what they think are four new species of amphipods, or shell-less crustaceans. At 26,247 feet (8,000 m), they observed Mariana snailfish and supergiant amphipods ( Alicella species) - creatures about 20 times larger than typical amphipods. ![]() They saw arrowtooth eels at 9,843 feet (3,000 m) and a wriggly little spoon worm ( Echuria) at 22,966 feet (7,000 m). "There were some small, translucent animals," gently moving about, Vescovo said. They also observed a variety of critters. In the depths, during those five dives, they discovered red and yellow rocky outcrops that could be chemical deposits or bacterial mats, which are made by chemosynthetic microbes, meaning they can convert carbon-containing molecules into organic matter. After Vescovo's record-breaking dive, other team members took four other subsequent dives to the trench. "I was surrounded by enormous pressure, but I was safely cocooned in my technological bubble." The pressure at that depth is about 16,000 pounds per square inch, over a thousand times more than the pressure at sea level. It was chilly it was quiet and "it was so very peaceful," he told Live Science.
