Abstract :
Hydras are freshwater cnidarians. They are found on all the continents except Antarctica, and they are also found on Continental Island but are apparently absent from oceanic island. The two species of brown hydra, Hydra vulgaris (Pallas, 1766) and Hydra oligactis (Pallas, 1766) were recorded for the first time in Iraq from samples collected from two ponds in Erbil province Northern part of Iraq during May 2013. Some physical and chemical properties of water were studied among them; water temperature reached to 22.5 ºC, with neutral pH value most of other studied parameters indicated that water is clean, cool and not polluted.
