Eight new deep-sea species of marine sponges discovered
The study identified 36 tetractinellid species and added eight new ones, highlighting unexplored caves and seamounts as key habitats for conservation.
Scientists with the Nippon Foundation-Nekton Ocean Census discovered 1,121 new marine species over the past year, increasing the global rate of marine species discovery by 54 percent.
Researchers conducted 13 expeditions ranging from shallow Mediterranean sea caves to depths exceeding 21,500 feet, documenting marine life across some of the ocean's least explored regions.
Notable finds include a "Ghost Shark" chimaera identified in Australia's Coral Sea Marine Park and a carnivorous "ping-pong ball" sponge from the South Atlantic using delicate stalks to trap prey.
The initiative recently launched an open-access platform called NOVA, allowing discoveries to be digitally shared within days instead of years, while formal description provides a "passport" for each new species.
Scientists estimate that up to 90 percent of marine species remain undocumented, while ocean life faces warming, acidification, and deep-sea mining pressures that threaten habitats before they are studied.
Ocean Census mission has identified marine species never before seen: giant molluscs, ghost sharks and organisms capable of surviving extreme pressures six kilometres deep.
