"Sound artist captures secrets of world's heaviest organism through eavesdropping"
Sound artist Jeff Rice has used hydrophones to listen to Pando, a vast living entity in Utah thought to be the world's heaviest organism. The 47,000 genetically identical quivering aspens are considered to be a single organism, with the "trees" actually branches thought to be connected by a shared root system. Rice placed a hydrophone inside a hole at the base of one of the branches, and lowered it down to touch the roots. He recorded the sound of millions of leaves in the forest, vibrating the tree and passing down through the branches, down into the earth.
