Galaxy with blue tendrils

This is a ‘sliding’ merger of a pair of LSB twins - with one flipped horizontally.

The proto-bar is typical of this kind of merger

The blue clumps are arm seeds (IMHO)… as they spawn stars and grow, the clumps become baby clouds, they become clouds, the clouds grow into each other and you have the familiar lumpy arms of a spiral… probably still LSB, but it will keep on growing.
