Would it be possible for a giant biological creature to live in space?

I'm think about something like the starship Enterprise of the Battlestar Galactica, but in a biological form ... Would it be possible??

Anything is possible.  But likely?

I think an advanced race could genetically engineer space critters certainly.   But for one to evolve to live in space would be very strange.  

A space critter following our current understanding of physics is going to be stuck in space.  So no dipping down to planets to munch on organics.  So it needs to get both its energy and its food from space, and be able to survive the temperature gradients and the radiation.  

Maybe giant space plants, or wierd funguses, orbiting stars.
