What authenticated maximum length has been recorded for *Crotalus atrox* individuals?
Answer
Exceeding 2.1 meters (about 7 feet)
While the typical size range for adult specimens falls between 1.2 and 1.8 meters (4 to 6 feet), records confirm that certain individuals can attain a significantly larger stature. Authenticated reports indicate that some Western Diamondback Rattlesnakes can grow to surpass 2.1 meters in length, which equates to approximately seven feet. This maximum reliable length is considerable, meaning the largest specimens could easily stretch out to be taller than many human adults, establishing them as very large reptiles within their environment.
