Giant Sponge
This sponge is the largest sponge documented to date, close to 3.7 meters (12 feet long) and 2.1 meters (7 feet) wide, comparable in size to a minivan. It was documented during the 2015 Hohonu Moana: Exploring Deepwaters off Hawaiʻi expedition aboard NOAA Ship Okeanos Explorer while exploring deepwater habitats in the Papahānaumokuākea Marine National Monument using remotely operated vehicles at depths ranging between 700-4,875 meters (2,300–16,000 feet).
