Animal life includes wolves, hyenas, mongooses, baboons, hares, sand rats, and jerboas. There used to be many larger animals such as gazelles, oryx, and leopards. By the 1950s hunting from motor vehicles made these animals almost extinct. Birds include falcons (which are caught and trained for hunting), eagles, hawks, vultures, sand grouse and bulbuls. There are several species of snakes, many of which are venomous, and numerous types of lizards. There is a wide variety of marine life in the Persian Gulf.
