Venezuela has suffered a severe academic and research management crisis, and funding opportunities for marine research and data management have been practically absent. This has worsened over the past five years, and as a result, libraries and other institutional spaces have been repeatedly vandalized, with hundreds of records, specimens, and historical data stolen, destroyed, or burned. To avoid the loss of irreplaceable data on Venezuelan biodiversity, an initiative aimed at digitizing information to create a rich dataset of biodiversity records, with emphasis on marine protected areas for the country, as well as to fill gaps in the distribution and status of marine biodiversity in Venezuela. Around 10 institutions in the country focusing on marine science have consistently produced a wealth of information about Venezuela’s marine biodiversity in the form of specimen collections, unpublished sampled data, and research theses through the work of hundreds of researchers and students. An inventory of available data sources at these national institutions was conducted under the National Biodiversity Data Mobilization Grant and the Biodiversity Information for Development Program, together with the Global Biodiversity Information Facility (GBIF) support. All recovered and processed datasets were published in the Ocean Biodiversity Information System (OBIS) and the Global Biodiversity Information Facility (GBIF) repositories.

This data collection represents a major contribution to the marine biodiversity inventory in Venezuela. It is based on numerous published papers, reports, books, and checklists provided by experts, covering a broad taxonomic collection of 3,041 marine species, with representatives of each of the five kingdoms: Animalia, Chromista, Bacteria, Plantae, and Protozoa. The datasets provide information on occurrence since 1822, extending the temporal coverage of the species occurrence inventory for Venezuela, which was established in 1879 before this project. The species occrrences are organized into 59 datasets containing 40,881 records, which represent a 28.49% contribution to the records of Venezuelan marine biodiversity reported to the OBIS (143,513 records in OBIS until November 2022). The number of records for Venezuela increased by 41.3% compared with the data available before the project. Most of the occurrences (63.47%) were registered in Marine Protected Areas. Data collection included records of non-native species, descriptions of new species, and species listed under different IUCN categories.
