Scientists discover the first multi-cellular animals that can survive entirely without oxygen, located in the briny depths of the Mediterranean's L'Atalante Basin. Adam Frucci gets excited:

This is interesting not only for the study of our oceans, but for life off our planet as well. After all, if life can exist where there's no oxygen, what's to say life can't exist in some of the harsher atmospheres that exist on other planets and moons?
