nat geo show is amazing. the life forms that don't require sunlight to survive are mind blowing. most impressed by the towering plumes of hot water that reach thousands of feet upwards carrying life with them only to cool, fan out into discs rotating with the earth, breaking away from plume to dump the larvae of all the life that rose with them. truly amazing at the survival instincts for organisms with out a brain. if you have not seen this show... it's a must see.
