Cascade Rock Crawler
A rare, eyeless rock crawler found in lava tube caves in the Cascade Range. It is adapted to permanent darkness and cold temperatures.
Did You Know?
It was discovered in a lava tube cave and has greatly reduced eyes.
Northern Rock Crawler
A rare ice-dwelling insect that lives on glaciers and snowfields at near-freezing temperatures. Handling one with bare hands can overheat and kill it.
Did You Know?
Rock crawlers are so cold-adapted that a human hand is hot enough to kill them — they prefer temperatures between 1-4C and die above 20C.
