Several papers addressed the systematics of snakes of Jordan (Disi, 1983, 1985, 1987, 1990, 1993, 1996, 2002; Disi et al., 1988 a and b, 1999, 2001, 2004; Al-Oran, 2000; Al-Oran and Amr, 1995, Al-Oran et al., 1997, 1998, Amr et al., 1994, 1997; Abu Baker et al., 2002, 2004; El-Oran, 1994; Modry et al., 2004; Joger et al., 2005; Venchi and Sindaco, 2006; Amr,  2008; Shwayat et al., 2009).  Within the past 20 years, major changes in the systematics of the snakes of the Middle East took place. The most comprehensive study on the snakes of Jordan was published by Amr and Disi (2011) with updates of their taxonomic status and distribution. At present the snake fauna of Jordan consists of 37 species and subspecies belonging to seven families (Typhlopidae, Leptotyphlopidae, Boidae, Colubridae, Atractaspididae, Elapidae and Viperidae).  Venomous species belong to three families (Atractaspididae, Elapidae and Viperidae) with a total of seven species on known toxicity.
