Hydrus (Latin for Hydra, also referred to as "male Hydra" or "little Hydra") is a minor southern constellation. The constellation was one of twelve constellations created by Pieter Dirkszoon Keyser and Frederick de Houtman between 1595 and 1597, and it first appeared in Johann Bayer's Uranometria of 1603. It should not be confused with Hydra.

It was listed in Johann Bayer's Uranometrica in 1603. http://chandra.harvard.edu/photo/constellations/hydrus.html Mythology There is no mythology commonly associated with Hydrus because it was not visible to the ancient Greeks. Hydrus was not discovered until modern times due to its position in the sky. It does serve, however, as the setting for the modern-day science fiction novel Serpent's Reach by C. J. Cherryh.
