What did scientists find when they explored the deep sea off Argentina?
28 possible new species - and an old VHS tape from the 1990s.
The answer
In 2025, marine biologists exploring the deep South Atlantic off the coast of Argentina identified 28 possible new species including sea snails, urchins, anemones, and worms. Using advanced lab techniques for DNA analysis and morphological study, the team documented life in one of the ocean's least-explored regions. In a surreal twist, among the biological specimens they also found a discarded VHS tape from the 1990s resting on the ocean floor - a stark reminder that even the most remote marine environments bear traces of human activity. The expedition highlights both the incredible biodiversity waiting to be discovered in the deep ocean and the pervasive reach of human pollution into Earth's last pristine habitats.
