Those are commensal tube worms growing on a vase type sponge.

is that normal ? do the worms live in there or do they eat/take it over ???
At first I thought it was coral with there guts out to feed ( blue planet coral reef section ) but just didn't look right and it was the middle of the day

The worms do not harm the sponge. Commensal relationships usually means that only one organism benefits from the association, in this case the worm, without harming the other organism.

This is not unusual at all.
