Article Synopsis
- Ceriantharia is a subclass of marine invertebrates known as tube-dwelling organisms, with five species found in specific oceans but none recorded in the South Atlantic. A new species from Uruguay and Brazil is described based on its life cycle.
- The research involved collecting larvae using a plankton net and observing their development over two years, along with descriptions of adult specimens collected in Uruguay, focusing on their anatomy and morphology.
- Findings revealed a unique type of larva that briefly exists in plankton, ultimately developing into polyps with distinct features and a novel crawling behavior not previously known in Ceriantharia.
As the effects of the Global Climate Changes on the costal regions of Central and South Americas advance, there is proportionally little research being made to understand such impacts. This commentary puts forward a series of propositions of strategies to improve performance of Central and South American science and policy making in order to cope with the future impacts of the Global Climate Changes in their coastal habitats.

The 10 countries that border these coasts have different research capabilities and taxonomic traditions that affect taxonomic knowledge. This paper analyzes the status of knowledge of marine biodiversity in five subregions along the Atlantic and Pacific coasts of South America (SA): the Tropical East Pacific, the Humboldt Current,the Patagonian Shelf, the Brazilian Shelves, and the Tropical West Atlantic, and it provides a review of ecosystem threats and regional marine conservation strategies.
