Marine biologists from the Schmidt Ocean Institute discovered 28 new deep-sea species in Argentina’s South Atlantic waters. Found near cold seeps, these organisms thrive in methane-rich ecosystems. The discovery includes rare squid, corals, and worms, highlighting the ocean’s unexplored biodiversity and the urgent need for conservation.
The discovery was made during expeditions aboard the research vessel Falkor (too), where remotely operated vehicles (ROVs) captured images and samples. Scientists were initially studying cold seeps but uncovered a thriving ecosystem with previously unknown species.
Cold Seeps And Biodiversity
Cold seeps are deep-sea areas where methane and other chemicals sustain microbial life, which in turn supports larger organisms like clams, mussels, and corals.
Species Highlights
Among the discoveries were rare Antarctic squid, deep-sea worms, and the world’s largest cold-water coral reef, expanding knowledge of marine ecosystems.
Conservation Importance
The findings emphasize the need to protect fragile deep-sea habitats from threats such as deep-sea mining, ghost fishing gear, and climate change.
Key Highlights
• 28 new deep-sea species discovered off Argentina
• Found near cold seeps rich in methane emissions
• Includes rare squid, worms, and cold-water coral reefs
• Research conducted aboard Schmidt Ocean Institute’s Falkor (too)
• Highlights urgent need for marine conservation and habitat protection
