In a groundbreaking discovery, researchers have unveiled a vibrant ecosystem teeming with life beneath the ocean floor. The findings include giant tubeworms, snails, and various other creatures living at depths of 2,500 meters in the Pacific Ocean, particularly around deep-sea hydrothermal vents. This remarkable trove of animal life, previously unknown, underscores the resilience of these organisms under high-pressure conditions and offers new insights into the potential for life beyond Earth. Scientists were surprised to find these animals, especially large worms over a foot and a half long, reproducing in such extreme environments, challenging previous assumptions about the limits of life on our planet.
