It is the constellation in the southern sky. It means “the male water snake” in Latin but is also known as “the lesser water snake”. It lies between the two Magellanic Clouds, between Eridanus and the south celestial pole.

The constellation first appeared on a celestial globe by the Dutch astronomer Petrus Plancius in 1597. It houses the small and faint IC 1717, the spiral galaxy NGC 1511, globular cluster NGC 1466, and the irregular galaxy NGC 1473.

French astronomer Nicolas Louis de Lacaille gave the constellation the name l’Hydre Mâle in order to emphasize the difference in gender between Hydrus and Hydra.
