But hydra, along with some worms and other animals, take regeneration to the extreme. Near their mouthparts, hydra have a cluster of 50 to 300 cells called the head organizer; as its name implies, it directs the development of the head. If a hydra is beheaded, a new organizer can form and prompt the animal to regrow its head. Meanwhile, the head that was lopped off will sometimes regrow the lower portion of its body.<\/p>\n<p>Scientists have also successfully grafted hydra heads onto the decapitated bodies of other hydra. And if a hydra is torn into small clumps of cells, those clumps that include head organizer cells will regrow a full body, Macias-Mu\u00f1oz says.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Year 2021 \ud83d\ude17 Hydra belong to a larger group of invertebrates called cnidarians, which also includes sea anemones, corals, and jellyfish.
