纳米布沙漠甲虫靠雾水生存的奇妙进化
The Namib Desert, stretching along the coast of Namibia and Angola, is one of the oldest and driest places on Earth. Rainfall here is almost nonexistent — some years, it never comes at all. Yet life finds a way, and one of its most remarkable survivors is the fog-basking beetle of the genus *Stenocara*.
Every morning, when a thick fog rolls in from the Atlantic Ocean, these small black beetles climb to the top of dunes. They tilt their bodies forward, facing into the wind, and wait. Special bumps on their hardened wing cases attract microscopic water droplets, while waxy grooves channel the collected moisture directly toward their mouths. Within minutes, they drink their daily ration.
