A hydra’s appearance and eating habits alone give it a sci-fi feel, but its ability to regenerate its body — even its head — from only a scrap of tissue or pile of cells raises it to another ...

As the study authors created these maps, they noticed that not all heads are created equal. When a hydra budded, it took about 72 hours to grow a head, while regenerating a replacement head took ...

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 ...

Hydra heads aren’t true heads with brains -- instead, they are clusters of 50 to 300 cells near the creature’s mouth that organize development. The normal process by which a new head grows and splits ...

In certain cases, an entirely new animal can grow from a detached chunk of hydra tissue. On average, they replace all their cells every 20 days, reports Discover magazine’s Katharine Gammon.

New research describes how real-life hydra can use epigenetics to regenerate their heads, rendering them effectively immortal.

How Hydras Regenerate Decapitated Heads. Hydra vulgaris constantly replenish the cells in their heads and grow new ones to reproduce asexually. But gene expression analyses reveal that regenerating a ...

In all other cases, you grow new heads as follows: Let x be the vertex where the head you just cut off was attached to the Hydra. Go down one edge from x, let y be the new vertex.
