Have you ever wondered what the largest living organism on Earth is? Well, you might be surprised to learn that it's not a giant blue whale or a sequoia tree; it's a fungus!

The humongous fungus grows throughout Malheur National Forest in Oregon’s Blue Mountains. It spans over 2,385 acres — an area roughly the size of 1,665 football fields. Scientists estimate the organism to be around 8,000 years old.
