Aren't the auto turrets the things that lock on and shoot you, those cannons on the ceiling? Yes. . . they're all over the freaking place, especially in the phazon mines.
Just be sure you get the barbed war wasps, the fast ones, that incenerator drone (<- all from Chozo ruins), and those parasites (and queen parasite) from the space station. There are more, probably, but that's all I can think of offhand.
