Crotalus tigris

Summary ⁷

Crotalus tigris is a highly venomous pit viper species found in the southwestern United States and northwestern Mexico. No subspecies are currently recognized. The specific name, tigris, Latin for "tiger", refers to the many narrow dorsal crossbands, which create a pattern of vertical stripes when viewed from the side.

Range description ⁸

The species' range extends from central Arizona south through south-central Arizona in the United States (Lowe et al. 1986, Painter and Milensky, 1993, Howland et al. 2002), to southern Sonora, Mexico, including Isla Tiburon in the Gulf of California, at elevations from sea level to about 1,465m asl (4,800 feet) (Stebbins 2003, Campbell and Lamar 2004). Reported occurrences at higher elevations have not been confirmed (Campbell and Lamar 2004).
