In the past year, scientists have identified over 1,000 new marine species, including carnivorous 'death balls' and translucent 'ghost sharks'. These discoveries highlight the vast unexplored biodiversity in Earth's oceans, which cover 70% of the planet.
- 01Among the newly discovered species are 'death ball' sponges that use velcro-like hooks to catch prey, found at depths of 3,601 meters.
- 02A new type of 'ghost shark' was identified in the Australian Coral Sea at over 800 meters depth.
- 03The Ocean Census, supported by the Nippon Foundation and Nekton, aims to catalog marine life, estimating up to two million species may exist in the oceans.
- 04Only 240,000 marine species have been formally recognized to date, indicating vast unexplored biodiversity.
- 05Program director Oliver Steeds emphasized the importance of exploring our oceans, suggesting it is more cost-effective than extraterrestrial explorations.

Scientists have made remarkable discoveries in the oceans over the past year, identifying 1,121 new marine species. Among these are unique creatures such as the 'death ball' sponge, which captures crustaceans with velcro-like hooks at depths of 3,601 meters in the South Sandwich Islands. Additionally, a new type of 'ghost shark' was found in the Australian Coral Sea at depths exceeding 800 meters. The findings were part of the Ocean Census, a collaborative project supported by the Nippon Foundation and the Nekton charity, aimed at cataloging marine biodiversity. Researchers estimate that there could be as many as two million species yet to be discovered in the oceans, which cover 70% of the Earth. Currently, only 240,000 species have been documented. Program director Oliver Steeds noted the importance of ocean exploration, arguing that understanding life on our own planet is crucial and more affordable than searching for life on other celestial bodies.
