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.
Japanese Ice Crawler
A nocturnal wingless insect found at high elevations in Japan. One of the most primitive living insects, often called a living fossil from the Permian period.
Did You Know?
Ice crawlers are considered living fossils — their order dates back to the Permian period, 250 million years ago, before the dinosaurs evolved.
