This looks like possibly the image quality isn't so great -- all those greenish things look like noise to me too. If you click on "Galaxy Zoo examine" and then "View on SkyServer", you can see all the information SDSS has on the galaxy. Clicking either "Navigate" or just on the thumbnail image will let you see what's around this galaxy, and there are a lot of reddish and/or greenish splodges around, so I suspect this is just an artifact.
