Glittery and shiny color on bristle worm

[Ryan's.Reef]

So I have a few bristle worms in my tank.. however in this video it seems that it has a green or greenish blue shimmer to the top of it. Is this just from the lights or the shimmer of the water? Just curious if anyone knows?

It looks like the worm may be iridescent (a number of polychaetes are) - very neat!

Any chance you could get some top-down pics of it (i.e. looking down at the dorsal side of the worm) with its head in the shot?
