Merger?

Is this really a form of merger, or just seemingly. I do not see strong connection between the two.

Both galaxies look disturbed. Merger for me

The problem is that the larger object isn't distorted in the Z direction (perpendicular to axis of rotation). This suggests it is not a merger. But both spirals appear to have prominent nuclei, the larger have prominent dark lanes and there is what might be tidal debris between and below both (but equally well this could be part of an arm of the smaller spiral).
I couldn't access the data at different wavelengths but I'd want more data before going further.

It is one of those artificially redshifted SDSS images.: If you click on the image, there is a remark below. There is a related GZ blog post.: http://blog.galaxyzoo.org/2013/10/15/galaxy-zoo-continues-to-evolve/
Below there is the original SDSS (DR9) image.: Please note, that the image is rotated.: It is the GPair ARP 294.:
I think, that it is a #merger.:Both galaxies have tidal debris. Besides they have close redshifts according to NED.
http://skyserver.sdss3.org/dr9/en/tools/chart/navi.asp?ra=174.9378&dec=31.92819&opt=PS: It was one of the mergers. which were simulated in the Merger Zoo Project, but that project is over.: Here are the top simulations.: http://mergers.galaxyzoo.org/render_top_sims?ref=http://s3.amazonaws.com/zoo-mergers-assets/sdss587739647284805725.png

I found the original GZ image in Talk.:

Here is another redshifted version of the same Galaxy Pair.:
