MOSCOW, Idaho — A University of Idaho graduate student recently found a rare giant Palouse earthworm.

Yaniria Sanchez-de Leon is apparently the first person in nearly two decades to find a specimen of the worm, which can reportedly grow to 3 feet long. She found the 6-inch white worm in May while digging at Washington State University's Smoot Hill Ecological Preserve near Palouse, Wash.
