Siberian Ice Crawler
A rare ice crawler found in the Russian Far East. It inhabits mossy rock fields and emerges at night during near-freezing temperatures.
Did You Know?
Ice crawlers are considered living fossils, belonging to an order that has survived largely unchanged since the Permian period.
Giant Stonefly
Large aquatic insects whose nymphs require pristine, cold, oxygen-rich streams. Adults are poor fliers and stay near water. Important food source for trout.
Did You Know?
Stonefly nymphs are so sensitive to water pollution that their presence is used by scientists as a living indicator of water quality — no stoneflies means polluted water.
