A 35-day deep-sea expedition in Australia's Coral Sea Marine Park has led to the discovery of over 100 new species, including unique sharks, rays, and fish. Scientists aboard CSIRO's Investigator research vessel explored depths from 650 feet to nearly 10,000 feet, identifying more than 110 new fish and invertebrates. Notable finds include a new ray species, a deepwater catshark, a skate, and a chimera, all adapted to extreme environments. Genetic testing is ongoing to confirm additional species. Researchers emphasize the urgency of understanding and protecting these deep-sea ecosystems, which are vital for biodiversity and face increasing threats from overfishing, climate change, and potential deep-sea mining.
