Tadpole galaxies? That's a new one for me.

Must be an early type.

And that's just the ones larger than 10 pixels.. incredible.

"Tadpole" galaxies are defined here (http://adsabs.harvard.edu/abs/2002PASP..114..797V).

If you can't be bothered looking at the link in dgruss' post, tadpole-like galaxies are ones with the main galaxy forming a 'head' and a tidal arm caused by a merger forming the 'tail'. For a picture look at this (http://en.wikipedia.org/wiki/Tadpole_Galaxy) link which shows the original Tadpole Galaxy.

Thanks matt.o. That's the only thing I found earlier with a quick search, so I presumed it was the 'template'. Good to have it confirmed. I did have a look at the link- hard going! :)
