Unlike the stem cells of an adult human, the stem cells of an adult Hydra—a small freshwater invertebrate related to jellyfish and corals—are in a constant state of renewal, bestowing it with amazing regenerative capabilities and nearly biological immortality. Around 100,000 cells make up the Hydra body, and amazingly, these cells renew every 20 days thanks to the Hydra’s bottomless well of stem cells.
