Glowing orange spots inside of hammer

[The_Skrimp]

Hi folks
I have a question I've been wondering about for a little while now and I can't seem to find an answer online. I've been seeing glowing red/orange spots inside of my hammer coral's tentacles. They move independently of the rest of the tentacle almost like they're some kind of organ floating inside. They seem to be brightest whenever my hammer is having a really good day. I usually see them when it's extra fluffy.

Any idea what they are or what function they serve inside of a hammer coral?

I honestly can't tell; if the red arrows weren't pointing them out I wouldn't even know what I'm looking at.

nothing visible from the images. A Healthy looking specimen is all I can see.
