Dr. Lowman’s latest Nature’s Secrets column in newsobserver.com:
It sounds like a horror movie – billions of miniature, bear-like creatures crawling through the lawns and shrubbery in Raleigh, Charlotte and Durham. Neither drought nor flood nor extreme temperature will kill them. During a heat wave, they curl into a ball and wait for better conditions to “come back to life.” They dominate their miniature kingdom of soil, leaf surfaces and water droplets. These invincible, microscopic beasts are… tardigrades.
Tardigrade means “slow walker.” They’re also called water bears, bears of the moss or moss piglets. They thrive in water, coral islands, moist tropical forests, and even the extremes from deserts to Antarctic slopes. Dispersed on all seven continents, tardigrades may be the most common organism of N.C.
Fortunately, they are quite harmless. But it’s good to know and appreciate who lives in your neighborhood.
