After seeing video of shrimp thriving near the Marianas Trench where the water would be boiling except for the extreme depth then nothing else about habitation of life in extreme conditions surprises me. Boiling water or water temperatures below freezing with life nearby is entirely acceptable to me.
Now I am wondering why we bother to boil water to make it potable. ;-)
So-called "hydrothermal vents."
I had thought they were found primarily in divergent zones (where two tectonic plates are moving away from each other) - but apparently they are also found in subduction zones (like the Marianas Trench) and even in convergent boundaries.
Interesting!
