A sample of the Antarctic sea urchin, Sterechinus, found at approximately 300 meters depth at Kinnes Cove in the Antarctic Sound.
Antarctic feather star, Promachocrinus kerguelensis found at approximately 300 meters depth at Kinnes Cove in the Antarctic Sound.
A Vulnerable Marine Ecosystem indicator taxon, the primnoid coral, Fannyella, found at approximately 300 meters depth, at Kinnes Cove, Antarctic Sound.
Gorgonocephalus chilensis basket star (ventral view) from off Lecointe Island at around 570 meters depth, Gerlache Strait, Antarctic Peninsula. Listed as a Vulnerable Marine Ecosystem indicator taxon by the Commission that governs the Antarctic Ocean.
A comatulid feather star collected from a submarine dive off Brabant Island (Gerlache Strait, Antarctic Peninsula) at around 420 meters depth.
Many organisms are utilizing this dead gorgonian coral skeleton for substrate on which to attach: such as demosponges, hexactinellid glass sponges, bryozoans (or lace corals) and a pink alcyonacean soft coral.
A pycnogonid sea spider from around 560 meters off Lecointe Island (Gerlache Strait, Antarctic Peninsula). Although this specimen spans approx. 6 cm, some Antarctic sea spider species can grow to the size of a dinner plate.
A polynoid polychaete worm collected off Lecointe Island (Gerlache Strait, Antarctic Peninsula) at around 560 meters depth.
Krill, Euphausia superba, represent a critical component of the Antarctic food web, providing food for fish, whales, seals, penguins, albatross and other seabirds, as well as marine invertebrates.
Ophiuroid brittle stars can be found in any type of Antarctic seabed habitat. These were collected off Lecointe Island (Gerlache Strait, Antarctic Peninsula) at around 560 meters depth.
A dead gorgonian coral skeleton provides substrate and habitat for many other species including zoanthid polyps, antarcturid isopods (crustaceans), demosponges hexactinellid glass sponges and tube-dwelling polychaete worms. Collected at around 560 meters depth off Lecointe Island in the Gerlache Strait, Antarctic Peninsula.
