The Ocean Census has revealed a trove of marine life, including a mysterious worm, a glass castle-dwelling creature, and a host of other strange species. While the discovery of these creatures is exciting, it also highlights the vast unknowns of our planet's biodiversity. The Ocean Census, a joint mission of the UK-based nonprofit Nekton and Japan's largest philanthropic organization, The Nippon Foundation, has found 1,121 previously unknown ocean species since last April. This marks a significant jump in the number of newly discovered marine species in a single year. The newly discovered creatures include fish, rays, sponges, and soft corals. One of the most intriguing discoveries is a worm known as Dalhousiella yabukii, which resides inside a glass sea sponge in the cold, dark waters off the coast of Japan. The Ocean Census's findings also include a new species of "ghost shark" off the coast of Australia, an unknown species of ray, and an unfamiliar example of a catshark. In the South Atlantic, scientists found an unknown variety of "sea pen," a kind of soft coral, and a carnivorous sea sponge covered in tiny Velcro-like hooks. However, the announcement from the Ocean Census must be taken with a grain of salt. Proving that a species is new to science is difficult and requires a thorough review of existing museum collections and academic literature. Many of the discoveries announced by the Ocean Census have not yet gone through this process and have not been formally described. This means it's not clear that all of these species are, in fact, new to science. The time between collecting a species and formally describing it as new takes about 13 years on average, which means some animals could go extinct before they're even described in the scientific literature. Formally describing and naming a species not only confirms that it's new but also makes it easier to study and conserve. The Ocean Census's findings highlight the vast unknowns of our planet's biodiversity and the importance of continued exploration and research. While the discovery of these creatures is exciting, it also underscores the need for further study and conservation efforts to protect these species and their habitats.
