Scientists have discovered the largest and, quite possibly, oldest sea sponge on Earth. The enormous sea sponge is estimated to be several hundred to several thousand years old, though it is impossible to know for sure.And at 11.5 feet (3.5 meters) in length, New Scientist reports, it’s as big as some cars.
Researchers came upon the sponge on a 7000-foot dive made by a remotely operated vehicle (ROV) at the Papah?naumoku?kea Marine National Monument in Hawaii last summer, according to Scoop. They published their findings this week in the journal Marine Biodiversity.
