The World Register of Marine Species (WoRMS) is an authoritative, comprehensive register for marine species. There are several synonyms that can be used to refer to WoRMS, including Global Biodiversity Information Facility (GBIF), Marine Species Identification Portal (MSIP), and Ocean Biogeographic Information System (OBIS). These synonym registers provide easy access to information on marine biodiversity, taxonomy, and ecology. They are essential resources for scientists, researchers, and conservationists who study marine life. By maintaining accurate information on the world's marine species, these registers facilitate a better understanding of the connections between different species and their habitats. They also help to inform policies and decisions that affect the conservation of marine biodiversity.
