It's the brown alga Dictyota which is well known for being iridescent. A big clump of these in the right light is an amazing sight. There are a couple of other genera in the family - Dictyotacea - which also reflect blue light.

Thanks for the ID.
One other creature has also eluded ID.
Is this some form of anemone?

It had a wonderful green glow when photographed without flash, which may just be the reflection of the water color.

The closest thing I can find is a basket star or pale sea cucumber, but I just can't bring myself to believe that.. yet.

Thanks!!

It's definitely a burrowing sea cucumber. There are several common species here (most are either orange, red or white). I'm not sure of the exact species name off the top of my head. Plus, latin has been dead for so long that it's starting to smell.
