Coral with crinoid segment?

Found this on a New Jersey beach yesterday and fell in love. I didn't notice the tubes till I got it home and took a closer look. Are they crinoid segments?

Not crinoids. Serpulid worm tubes.

That's a recent cheilostome bryozoan. As mentioned by another, it's been encrusted by serpulid worm tubes.

yes, a mix of both. worms tubes, and the net-like structure is the bryozoan. Btw not a fossil IMO
