Tardigrade
A tardigrade is a small animal. They can grow from 0.1 mm up to 1.5 mm. So yeah pretty small. They have been found all over the world. From the highest mountain in the world to the Antartic. From the deep sea to the warmest tropical forests. They are the strongest animal in the world because they can withstand extreme temperatures. They can survive in -270 degrees Celsius and they can survive in boiling hot water. They can even stop living and when there is food again they just come alive again. They have even been in space. Guess what. They can survive in space. In the absolute vacuum. Some tardigrades even layed eggs there. So there are even some in space right now. These are one of the extremest animals. And because they can withstand space people don't know if they are from space or not.
-270 degrees Celsius so I think they will survive the extremest winters. I made a tardigrade because I think he will survive the nuclear winter. I think this is great for this contest.
