Yeah, I think so too. I watched a very good documentary on Deep Sea Volcanoes on Netflix the other night, I knew about extremophiles but it went into really good detail. There's bacteria living on Earth deep inside the underwater vents the magma is shooting out -- a bacteria converts the poisonous metals into energy, a big game of symbiosis. Check that documentary out if you can - it details what happens after a vent shuts off too, there's an interesting creature that farms energy out of the corpses of all that stuff that was alive breathing the metals - and there's a possibility that such a place is where all life formed. The red tubeworms you've probably seen in most of the vent pictures get their red pigment from hemoglobin in their blood, just like ours. Pretty neat -- so similar to us, but soooo different.
