I'd urge you to read a fantastic high quality science book called "Evolving the Alien" written by Ian Stewart and Jack Cohen, check it out on Amazon. One of the best reads I have had in ages.

The opportunities for life are much more diverse than Astrobiologists like to believe/examine.

A very good read..
