A Twin-Spotted Rattlesnake<\/a> with a relatively drab pattern, but not atypical for an older adult. These are small snakes, rarely seen by hikers, as their range within the U.S. consists of only a handful of mountains in southeastern Arizona. In addition to rodents, these rattlesnakes also specialize in lizards, often taking the colorful Yarrows Spiny Lizards also common to rocky outcrops in high pine forests. These are among the protected species within Arizona, but a good number of them still end up being taken from the mountains each year to enter the European black market.<\/p>\n\n\n\n
