Hydra are simple cnidarians that live in freshwater and are as small as a grain of rize. Aproximately 50% of their body is made up of stem cells. They can make perfect copies of their stem cells, basically forever. It's called non-senescence which is basically biological inmortatily. Researches hope to understand their amazing ability to recover and regenerate so as to some day slow down human aging.
