Anyone have more info on this one? Is this two galaxies merging?

Probably not merging. The "bite" out of the big galaxy is likely a masking artifact.

Might be a satellite galaxy drawing in material.

Also a hint of a darker area in SDSS in between the two galaxies near the smaller one.

The satellite and the barred galaxy are at redshifts that put them physically near each other, so it's not a stretch to think they're interacting and this is perhaps just the start of some tidal effects that will develop further in the thousands and millions of years to come. 😃
