Hydras, simple fresh-water animals, have the ability to live forever if kept in ideal conditions, a recent study shows.
The organisms are made mostly of stem cells that have the ability to continually divide, thus constantly renewing the body.
“The differentiated cells of the tentacles and the foot are constantly being pushed off the body and replaced with new cells migrating from the body column,” Daniel Martinez, a biologist at Pomona College, said in a statement.
