Summary:
- Researchers used an underwater robot called "Lassie" to explore the seafloor beneath the Antarctic ice and discovered thousands of nests belonging to a rare type of icefish.
- The icefish nests were found in an area the size of the city of Paris, indicating a thriving population of these unique creatures that live and breed under the ice.
- The discovery provides valuable insights into the ecology and behavior of icefish, which are an important part of the Antarctic ecosystem and can help scientists better understand the impacts of climate change on these fragile environments.
