Scientists found fifty-seven new deep-sea species in Argentina
An international team of biologists identified fifty-seven new species off the coast of Argentina during a recent deep-sea expedition.
Biologists gathered in Buenos Aires to analyze specimens collected by the remotely operated vehicle SuBastian in August 2025. They named fifty-seven new species and five new genera within just two weeks of examining the samples.
Most specimens came from the Mar del Plata Canyon, a deep rift where warm currents collide with cold waters. This energetic region plunges to more than three thousand five hundred meters below the ocean surface and hosts unique life.
The expedition aimed to document marine life before threats like climate change disrupt these fragile deep-sea ecosystems. Oceanographer Jyotika Virmani noted that world-class technology meeting international collaboration showed great power for discovery.
Taxonomists examined copepods and found every single one was new to science, contributing twenty new species total. They also identified twenty-two new echinoderm species and fourteen cnidarians including striking octocorals and vivid purple sea cucumbers.
“These results show the power when world-class technology and expertise meets international scientific collaboration.”
