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.
Mount Halla Ice Crawler
A Korean ice crawler restricted to the high elevations of Mount Halla on Jeju Island. It is nocturnal and emerges only during freezing conditions.
Did You Know?
Climate warming directly threatens this species as its cold mountain habitat shrinks upward with no higher ground to retreat to.
