Genus Atractosteus Rafinesque, 1820

10. Atractosteus spatula (Lacepède, 1803) [I]-[NE], Alligator gar/Tigris, Persian Gulf basin (Esmaeili et al. 2017b, 2018).

Remark: It has been reported from the southern reaches of the Arvand River/Shatt al-Arab River at Om-al-Rasas Island, Basrah, Iraq during an ichthyologic survey in September 2016 (Mutlak et al., 2017) and from Marivan (Zarivar) Lake, a Tigris River tributary of Iran (Esmaeili et al., 2017b). The aquarium trade pathway is the suspected factor for the presence of this species in the freshwater area of Iran and Iraq. Monitoring of inland waters is recommended.
