Deepwater discoveries: scientists find more than 110 new fish and invertebrate species in the Coral Sea

Marine scientists have discovered more than 110 new fish and invertebrate species in the Coral Sea off Australia's Queensland coast, with researchers expecting the total could exceed 200 as identification continues. The species—including brittlestars, sea anemones, and a catshark—were collected during an expedition in waters 200 metres to 3 kilometres deep within the Coral Sea Marine Park, Australia's largest marine protected area spanning nearly 1 million square kilometres east of the Great Barrier Reef. The discovery underscores how little is known about deep-ocean ecosystems and suggests the Coral Sea remains a biodiversity hotspot despite its remote location. The findings add to the scientific understanding of the region's biological diversity and could inform conservation strategies for the marine protected area. Such deep-sea discoveries are rare and typically require specialized expedition vessels capable of reaching extreme ocean depths.
