Scientific Efficiency and Tech Innovation Fuel Historic Deep-Sea Discoveries in South Atlantic
Operating with remarkable speed and cutting-edge tools, a Smithsonian-led international coalition showcases the power of structured exploration off the Brazilian coast.

A masterclass in scientific efficiency and technological innovation has unfolded off the coast of Brazil, where an elite international team of researchers discovered 31 new species in a mere fortnight. This record-breaking expedition demonstrates how targeted investment in cutting-edge technology and disciplined scientific leadership can yield unprecedented results in exploring the natural order.
Led by Dr. Karen Osborn of the Smithsonian National Museum of Natural History, the expedition brought together twenty-four highly skilled experts from the United States, Australia, Brazil, and Japan. Departing from Salvador, Bahia, the crew of the Falkor (too)—a vessel operated by the Schmidt Ocean Institute with backing from the University of Western Australia—executed their mission with military-style precision.
The expedition’s objective was the ocean's midwater, the largest and most strategically significant habitat on the planet, containing 90 percent of Earth's living space. Despite its scale, this zone has remained largely uncharted. The structured approach of this team highlights the importance of systematic exploration to catalog the Earth's natural resources and biological assets.
The newly discovered species reflect the complex, highly ordered design of the marine biosphere. Among the findings were an amphipod crustacean, a fast-moving gossamer worm, nine jellyfish, seven siphonophores, and seven comb jellies. Each organism plays a specific role in the deep-sea ecosystem, demonstrating the intricate balance of the natural world.
The team also cataloged four larvaceans—creatures that inhabit self-constructed mucus shelters and possess a spinal cord-like structure that relates them more closely to humans than invertebrates—alongside two giant, single-celled rhizarians. These discoveries enrich our taxonomical archives and reinforce the value of classical biological classification.
The unparalleled speed of these discoveries was driven by a breakthrough tool developed by the expedition's engineering team: a spinning wheel confocal microscope nicknamed "the Squid." By employing high-powered lasers to scan microscopic details, the Squid bypassed weeks of traditional lab preparation, allowing for immediate, real-time analysis of living 3D cellular structures.
"That opens up a whole new world of exploring," explained Dr. Osborn, emphasizing the operational efficiency of the new system. Rather than relying on slow, outdated methods of chemical staining and slide mounting, the team observed cellular interactions and skeletal development live on the ship. This technological leap dramatically reduces the cost and time required for biological verification.
