Bramble bamboo coral. These colonies (at least when younger have very thin branches and grow in these tangled thickets. You can see the polyps arising from several branches; they are very widely spaced along each branch. There appears to be a sponge intertwined with the bramble; the parts of the sponge that are brownish are dead, and the living parts white.
