Why does this animal never age? - Raymond Adkins

O tym filmie

Explore the incredible regenerative abilities of hydras, and get to know their biology to find out if they're really immortal. -- In 1740, naturalist Abraham Trembley found something shocking in pondwater. He couldn't tell if it was a plant or an animal, though its way of moving and consuming things seemed animal-like. But when he cut parts off or even split it in two, it regenerated, which was decidedly plant-like. So, what was this miraculous creature? Raymond Adkins explores the near-immortal biology of the hydra. Lesson by Raymond Adkins, directed by Sharon Colman.
