This rosy Tritonia tetraquetra nudibranch was seen sitting on a marker at the Pinnacle, west of Southern Hydrate Ridge. It was near some soft corals, some of which were missing polyps, and had clearly been grazed on by this sea pen and soft coral specialist predator! Photo credit: UW/NSF-OOI/CSSF, Dive R2228, V22.

Bathydoris aioca, an unusually large (~30 cm) deep-sea nudibranch, was part of a unique community of invertebrates gathered around the anchor of the Slope Base profiler mooring in 2900 meters (~9500 feet) of water, also including flytrap anemones, galatheid crabs, and sea cucumbers.
