Super Animals – Tardigrades!

supertardiThe animal world has it’s own super hero, Tardigrades a.k.a water bears! Just like Superman, they are able to withstand extreme temperatures, radiation, extreme pressures! According to wikipedia they “can survive in extreme environments. For example, they can withstand temperatures from just above absolute zero to well above the boiling point of water (100°C), pressures about six times greater than those found in the deepest ocean trenches, ionizing radiation at doses hundreds of times higher than the lethal dose for a human, and the vacuum of outer space. They can go without food or water for more than 10 years, drying out to the point where they are 3% or less water, only to rehydrate, forage, and reproduce.” And they look crazy weird, like a cross between a caterpillar and a bear. If only they weren’t microscpic, they could be the next Sea Monkeys!

In this video, Hank Green gives us the low down on these creatures.
