The Lernaean Hydra

The Lernaean Hydra (lur-nay-in hy-druh) was a Greek dragon.

Mythology
The Lernaean Hydra was a nine-headed serpent that lived in the swamps of Lerna. One of the labors of Heracles was to slay the beasts. However, when one of the Hydra's heads was cut off, two more grew back. With the advice of Athena, Heracles cut off each head and burned the necks so that the two more heads couldn't grow back. The Lernaean Hydra was later placed in the stars as the constellation Hydra.
