A scalloped portion of the wall in Heezen Canyon. The near-horizontal cracks are breaks between bedding (depositional layers), while the near-vertical cracks are fractures or joints that form when the buried rocks depressurize as they reach the seafloor through erosion.

"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.
