Retired police officer discovers an exceptionally rare white rattlesnake in Arizona, “once-in-a-lifetime” find

Retired police officer Phil Roberts discovered a rare white rattlesnake in Arizona.

The snake is not albino but likely has leucism, a genetic mutation causing partial pigmentation loss.

Experts described the find as a 'once-in-a-lifetime' event that many lifelong snake specialists never witness.

Roberts safely captured and relocated the snake after photographing it.

The pale rattlesnake has faint markings and normal-colored eyes, distinguishing it from albino animals.
