Subject: Are we all sun-suckers?

I've always been fascinated by the little knowledge i have about chemosynthetic 
organisms  (for example the bacteria that live in deep-sea vents).  To the best 
of my knowledge, they are the only category of life of which i know that do not 
derive their energy in some way, shape or form from the sun.  Are there any other 
non-phototrophic lifeforms? Are there any other ways in which they are 
fundamentally different from we phototrophs?   
	Let me tell you, when i first learned about chemosynthetes it blew my whole 
idea that the definition of life was that which slowed down light (i.e. using the 
free energy of a photon).  I would love to her from you!  If not, many thanks for 
this wonderful website.
