Pando, The Heaviest Organism On Earth
The heaviest organism on Earth has a name: Pando, or the Trembling Giant. It consists of around 47,000 genetically identical quaking aspen trees, and resides in Utah's Fishlake National Forest. The trees are technically a single organism united by their shared root system in a clonal colony, which sprawls for more than 100 acres, and is estimated to be anywhere from 80,000 to a million years old. Today, however, the trees are threatened by elk and deer that have been grazing on them aggressively. Learn more about the world's most impressive organisms.
