World's Largest Known Sponge Found in Deep Hawaiian Waters, Size of a Minivan

Marine scientists have documented a colossal sponge in the deep waters off Hawaii, measuring approximately 3.7 meters (12 feet) long and 2.1 meters (7 feet) wide—comparable to a minivan. Discovered at a depth of 2,100 meters (7,000 feet) within the Papahānaumokuākea Marine National Monument, this sponge is now recognized as the world's largest known specimen. The find was made during a deep-sea expedition using remotely operated vehicles, highlighting how little we know about deep-ocean biodiversity. Researchers have yet to determine the sponge's exact species, but its immense size suggests it could be centuries old, given the slow growth rates typical of deep-sea sponges. This discovery underscores the importance of protecting deep-sea habitats, which harbor unique and ancient life forms. As exploration technology advances, scientists anticipate uncovering more such giants, offering new insights into the resilience and longevity of marine organisms in extreme environments.
