Biodiversity Data Journal 9: e62813. https://doi.org/10.3897/BDJ.9.e62813 Abstract Background Several lists of marine fish from Azores have been published in the past. Most of those publications are difficult to access on line and several were not published in peer-reviewed journals. New information This checklist updates all the chondrichthyan records for the Azores Exclusive Economic Zone (EEZ), according to the most recent taxonomic classification of cartilaginous fish, as well as providing information on the conservation status for all species. We also present recent literature data on rare species and recent records for Azores. This is the first comprehensive list of cartilaginous fishes from Azores to be published in the GBIF database. © Barcelos L et al.

They can be found from the cold deep-sea to subtropical and tropical waters (Greemberg 2009). Sharks and rays have a great recreational and ecological interest (Vieira et al. 2020); however, many species worldwide are declining due to global overfishing (Worm et al. 2013). The total estimation for risk extinction, according to the IUCN Red List criteria, indicates that a quarter of all shark and ray species are threatened (Dulvy et al. 2014). The first comprehensive chondrichthyan checklist for Azores was published over 20 years ago by Santos et al. (1997). After that, some updates were made, most of them integrated in marine fish or biodiversity lists (e.g. Porteiro et al. 2010). In the meantime, new publications have emerged regarding new records (e.g. Catarino et al. 2020) or with new information on species already recorded for Azores (e.g. Das and Afonso 2017, Barcelos et al. 2018). The present work gives taxonomic updates and information regarding the conservation status (IUCN) for all chondrichthyan species from the Azores' EEZ (see Suppl. material 1). This is the first complete and updated list of chondrichthyans that can be found in the GBIF online platform (Barcelos et al. 2020). General description Purpose: Updating Azorean biota checklists.

Two new records have been registered and the taxonomy has been updated. New information regarding the specific occurrence of the rare Odontaspis ferox was recently published (see Barcelos et al. 2018). The first comprehensive chondrichthyan checklist was published by Santos et al. (1997) and later updated by Porteiro et al. (2010).

However, they were not included in this checklist because those authors, as well as other sources (e.g. IUCN’s Red List) report their occurrence as either doubtful or ‘need to be confirmed’. As such, this fact does not allow us to have a degree of confidence that these species were actually confirmed to occur within this checklist geographic area. Author contributions LMDB, JMNA and JPB published the updated checklist in GBIF IPT - Portugal and built the framework. LMDB developed this paper and uploaded all the files into the Arphahub platform. All authors read and edited the submitted version and agreed on its present version.
