Every year, the World Register of Marine Species (WoRMS) presents the 10 most remarkable new marine species of the previous year, in this case from 2023.
Here are the 10 most remarkable 10 new marine species from 2023:
Abyssocladia falkor (Falkor's Carnivorous Sponge,)
Tetranemertes bifrost (The Bifrost Nemertean)
Alaysia solwarawarriors (Solwarawarriors vestimentiferan, Vestimentifera worm from hydrothermal vent fields in the Manus Basin of the Bismarck Sea)
Kodama jujutsu, (Hannan's pygmy squit ,Hannan's pygmy squid)
Nautilus samoaensis (The Samoan Nautilus, Samoan Nautilus)
Xyloplax princealberti (Prince Albert's Sea Daisy, a deep-sea starfish)
Dorymenia boucheti (Bouchet's Dorymenia, a shell-less, worm-like mollusk)
Halgerda scripta (Fine Line Nudibranch, five-line nudibranch)
Kumimanu fordycei † ( Giant Penguin, Fordyce's extinct giant penguin)
Santjordia pagesi (St. George's Cross Medusa, Medusa with St. George's Cross)

The deep-sea sea sponge Abyssocladia falkor was collected by ROV in Canyon 8 as part of the expedition FK200802-Seamounts, Canyons & Reefs of the Coral Sea Cruise on the RV Falkor of the Schmidt Ocean Institute.
The holotype consists of a stalked sponge with a short stalk and a disc-shaped body with filaments radiating in a single plane from the disc margin. The paratype has the entire stalk and roots, which were lost when the holotype was collected.
The holotype has a body diameter of 7.8 mm and is 1.3 mm thick.
The filaments are 2.3 mm long and 0.1 mm wide.
The paratype has a body with a diameter of 6.7 mm and a width of 1.6 mm, the stalk and root are 40 mm long, the filaments are up to 4.0 mm long.
Color: Cream-colored when alive in situ
The special thing about Abyssocladia falkor is the fact that this sponge has chosen a carnivorous diet, whereas the absolute majority of all sponges are filter feeders or suspension feeders.
The evolution of carnivory in sponges is interpreted to be a response to the more limited availability of particulate matter at depth
This species is most closely related to the Japanese species Abyssocladia natsushimae Ise & Vacelet, 2010.
Etymology: The species epithet "falkor" honors the research vessel (R/V) Falkor of the Schmidt Ocean Institute, from which an ROV dived into the Coral Sea and discovered the species.
