ernesto.azzurro@cnr.it Manuela D'Amen ISPRA Researcher manuela.damen@isprambiente.it Noemi Biancone CNR-IRPPS Technologist noemi.biancone@cnr.it Not applicable Mediterranean sea Georeferenced occurrence records were gathered through an extensive literature search mainly through Google Scholar, ISI Web of Science, and Scopus, by multiple search criteria and using the scientific names of the species and a combination of terms such as exotic, non-indigenous, alien in conjunction with the Mediterranean Sea and names of Mediterranean countries, in the title, abstract, and keywords. All records were manually verified to identify potential outliers and in-land data points. These records were checked against the information provided by the original source and manually moved to the localities indicated in the source, only when wrongly reported. Duplicate records were removed. The dataset structure was based on Darwin Core Standard (DwC, https://dwc.tdwg.org/), and taxonomic information was extracted from the World Register of Marine Species (WoRMS; www.marinespecies.org).

This updated version of ORMEF includes geo‑referenced records spanning the entire Mediterranean region from 1896 to January 1, 2026. The database currently contains 12841 occurrence records distributed across the territorial waters of 20 Mediterranean countries, sourced from 889 scientific publications. Each record extracted from the scientific literature was associated with a set of standardized information, including species name, year and month of observation, minimum and maximum depth, locality, and the country where the species was recorded. The corresponding bibliographic reference, representing the source of each geo‑referenced record, is also included in the database. The database will be periodically updated by checking the main journals devoted to the publication of exotic fish records. All data can be interactively explored through the new ORMEF web platform (www.ormef.eu). The user‑friendly interface allows precise visualization of geo‑referenced occurrences, with intuitive filtering and querying tools. The platform also features animated temporal reconstructions and customizable time-interval filters, enabling dynamic exploration of invasion patterns over time and space.
