They can take temperatures close to absolute zero and hotter than boiling water, withstand over 1000 times more radiation than humans, can live over a decade without water, endure six times the water pressure in the deepest ocean trench, and even survived in the vacuum of space, making them the only animals to do so. When conditions get though, they basically die, stopping any process in their miniature bodies for up to 120 years! When conditions get better again, they revive and go on with their lives.
Water bears really are miniature animals, having tiny legs, claws, eyes, mouth, stomach, and even nerves. They have such precise muscle control that they can even move like higher order animals.
You can find these fascinating creatures about everywhere: on the bottom of the ocean, under meters of ice, in hot springs, and on the top of the Himalaya! Preferring to live on moist lichens and mosses with up to 25000 of their little friends, you can bet that some water bears will be very close to you; even in your backyard! Go search for them yourself..!!
