Merger or not ?
Any idea what is happening here ?

Hi paulbidston and welcome to the Zoo
The central galaxy could be merging with the smaller one at the bottom. But then again , this blue blob at the bottom could be a star forming area of the central galaxy caused by an interaction with another galaxy (maybe a fly-by). So, as for classifications : I'd definitely go for disturbed, but merger is equably possible. Just give it your best shot. Sometimes, there is no right answer !
