Just noticed these little dots. Anyone know what they are? Thanks

Bump, I have seen them on all Euphyllia in the same anatomical area. Very curious for someone to chime in as to the function.

Looks to be anything from mucus production to controlling inflation of tentacles.

My hammer with the same dots/holes for further reference.
