A group of hikers in California’s Death Valley National Park got an unexpected thrill when they encountered a snow-white tarantula scuttling across a nighttime trail near Furnace Creek. The spider, about 7.5 centimeters (3 inches) wide, stopped under a flashlight beam, revealing a ghostly pale body rarely — if ever — seen in the wild.
“It looked like it had been dipped in flour,” said hiker Brandon Ortiz, who filmed the encounter. “We thought it had some kind of fungus. Then it moved.”
The footage was shared with park officials, who quickly looped in arachnologists from UC Riverside. Their verdict? It was likely a previously undocumented color morph or rare genetic mutation of Aphonopelma iodius, commonly known as the desert blonde tarantula.
Why White?
Tarantulas are typically earthy in tone — tan, brown, or black — to help them blend in with the desert terrain. But just like other animals, they can experience leucism, a genetic mutation that reduces pigment. Unlike albinism, leucistic animals retain normal eye color and are more viable in the wild.
Scientists say this rare spider could be the first leucistic tarantula ever recorded in the region. While it’s not a new species, it’s a remarkable example of how genetic quirks still surprise us in well-studied areas.
“It’s like the desert version of a white buffalo,” said Dr. Karen Shin, a spider specialist with the California Academy of Sciences.
A Race to Learn More
Park rangers have since installed motion-triggered cameras in the area, hoping to spot the white tarantula again. But so far, no luck.
- Tarantulas are mostly nocturnal and shy, often staying underground
- Sightings are rare even for common varieties, especially outside mating season
- No other white tarantulas have been reported in Death Valley — or anywhere else in California
Researchers urge the public not to disturb desert wildlife and to report unusual sightings to park staff immediately.
Nature’s Reminder
The white tarantula is a reminder that even in harsh, sun-blasted places like Death Valley, the natural world still holds surprises. Whether it’s a mutation, a morph, or a new subspecies waiting to be cataloged, one fact remains: you never know what’s crawling just off the trail.
