Recently, a new species of bear was discovered. It’s called the Water Bear, and they only grow to about 1 mm long. Water Bears are extremely aggressive, like most bears, but the cool thing is how resiliant they are. Water Bears can survive ANYTHING. They are the only animal to be exposed to the harsh conditions of outerspace and survive. I’m not kidding: http://www.sciencedaily.com/releases/2008/09/080908135906.htm.

Here’s a video of a Water Bear in action.
