Ocean Census Finds 1,121 New Species
20 May
Summary
- Over 1,121 new marine species were identified in one year.
- Discoveries include corals, crabs, shrimp, and a 'Ghost Shark'.
- New species found at depths exceeding four miles.

Marine scientists have identified a record 1,121 new species in the world's oceans within the last year, a remarkable 54% increase in discoveries. These findings represent a significant advancement in understanding and safeguarding marine biodiversity.
The discoveries span diverse life forms, including corals, crabs, shrimps, sea urchins, and anemones. Notably, a 'Ghost Shark' relative, a species predating dinosaurs, was found in Australia's Coral Sea. Researchers also documented symbiotic bristle worms within glass sponges in Japan and a vibrant new shrimp species in a French sea cave.
These breakthroughs emerged from 13 expeditions and nine workshops globally, highlighting successful international scientific collaboration. Experts emphasize that up to 90% of ocean species remain undiscovered, and documenting them is critical for effective conservation policies.
To combat the risk of species extinction before formal description, a process historically taking over 13 years, marine scientists are now formally recognizing 'discovered' species immediately. This accelerated approach is essential in the race to catalog and protect ocean life.
