Sablefish range from 30 cm to 61 cm in length. They can live up to 90 years with one fish having been documented living 94 years. Multiple sablefish were seen along the seafloor at 580 m down at the Oregon Off Shore site. Credit: UW/NSF-OOI/CSSF; ROPOS Dive 1770; V14.

These snails lay eggs in a spiral tower and the adult snail sits on top of the tower waiting for the eggs to hatch. The snails were all clustered together along a cable route SUM1W2 at Southern Hydrate Ridge. We did not see the snails at any location other than here. The depth at this location was 776 m.

These clams thrive in hydrogen sulfide-rich environments, like the methane seep at Einstein's Grotto at Southern Hydrate Ridge. They usually have white shells and are typically partially buried beneath the sediment. Credit: UW/NSF-OOI/CSSF; ROPOS Dive 1750; V14.

Hermit crabs belonging to the genus Pagurus use snail shells as homes. There are over 170 species of hermit crab in this genus. These two hermit crabs were seen at Southern Hydrate Ridge at depth of 774 m. The species was unable to be identified. Credit: UW/NSF-OOI/CSSF; ROPOS Dive 1750; V14

The Scarlet King Crab was seen at multiple locations along Hydrate Ridge. It was often found in sandier substrate, however it was also found among a large group of snails. Photo Credit: NSF-OOI/UW/CSSF; Dive 1758; V14

The Venus Flytrap Anemone resembles the carnivorous plant found on land. It is a member of the family “Actinoscyphiidae”, but it is unknown as to how many species there are. This anemone was seen at Slope Base at a depth of 2900 m rooted in the sediment on the seafloor. Photo Credit: NSF-OOI/UW/CSSF; Dive 1757; V14

The Voragonema pedunculata has been measured up to 4 cm in diameter. This jelly was found at Southern Hydrate Ridge around 790 m. Photo Credit: NSF-OOI/UW/CSSF; Dive 1769; V14

This coral is not rigid, but is soft -it does not produce a calcium carbonate skeleton. The soft coral is at Southern Hydrate Ridge and the Pinnacle at depths around 775 m deep.

Neptune Canada’s guide included it in the “sea anemone” category because of similarity, but it belongs to another order: Corallimorpharia. This Corallimorph anemone was spotted on the seafloor at Southern Hydrate Ridge at a depth of 774 m.

The Pom-Pom Anemone actually looks like a pom-pom. The anemone does not attach to any substrate, and it has the ability to roll along the sea floor like tumbleweed because ocean currents propel it. Photo Credit: NSF-OOI/UW/CSSF; Dive 1765; V14

Snailfish are scaleless with thin, loose gelatinous skin. This snailfish was seen at Southern Hydrate Ridge at a depth of about 600 m. Credit: UW/NSF-OOI/CSSF; ROPOS Dive 1774; V14.

This Sole at Southern Hydrate Ridge is at a depth of 769 m. It was laying along the seafloor in cobbly sediment. Credit: UW/NSF-OOI//CSSF; ROPOS Dive 1765; V14.

This sole is at Southern Hydrate Ridge at ~800 m water depth. Credit: UW/NSF-OOI/CSSF; ROPOS Dive R1765; V14.
