There's a sponge the size of a minivan 7,000 feet below the Pacific Ocean's surface.
Scientists with the National Oceanic and Atmospheric Administration discovered the largest-known sponge near the Hawaiian Islands. It is nearly 12 feet long and 7 feet wide.
It's unclear how old it is, but other huge sponges in much shallower waters are believed to live more than 2,300 years.
This massive sponge even acts as an important part of the ecosystem. The researchers say it filters large volumes of seawater and is a habitat for smaller species.
Crew aboard the Okeanos Explorer discovered the sponge and documented the find using remotely operated vehicles. Their exploration continued to a depth of 16,000 feet.
Only about 5 percent overall of the world's oceans have been explored, so even larger sponges may exist.
