Yes there are!  I'm pretty sure (but don't bet the farm on this) that
Proteus has been shown to "eat" other organisms.  They sense the prey swam
over it, lyse it and use the nutrients from the lysed organism.  If not
Proteus, there are other organisms that carry out this technique.  If you
get ASM news check back a couple of years and there is a good article
written by Bob Belas at the Center of Marine Biotechnology.  I think he
may mention it there.
