@bancho14344: Underground engineer: who is the giant mole rat? The giant mole rat is a rare rodent that lives underground in Eastern Europe, Asia, and the Caucasus. Nearly blind, its eyes are covered with skin. It navigates using smell and ground vibrations. Its teeth work like a pickaxe. It digs tunnels up to 100 meters long. The lips close behind the incisors, keeping soil out of the mouth. It feeds on roots and tubers. It lives in colonies with strict hierarchy. Tunnels include chambers for food, offspring, and waste. The system works like an anthill. Lifespan is up to 20 years. Naturally resistant to cancer. Scientists are studying its DNA to search for medical breakthroughs. First described in 1774 by German naturalist Peter Simon Pallas in the southern Russian steppes. #animals #molerat
