Exploratour: Life on Mars?
Life that Survives in Harsh Environments
It doesn't seem like there is life now on Mars. But maybe there is life that could live in an extreme environment like on Mars...or maybe Mars was different in the past. This is what we'll look at now.These are "smokers", and they live on the bottom of the ocean floor. There it is completely dark. It is also very cold, and there is a lot of pressure (think of how your ears feel when you dive to the bottom of the swimming pool).
This is an environment like you might find on another planet, and there are creatures which can live in it.
