Corals are some of the conspicuous taxa in deep-sea ecosystems. Yet, characterizing coral diversity is difficult and requires a combination of both morphological and genetic data. Many leading coral taxonomy experts are close-to retirement or have already retired. It is now imperative that the hands-on expertise that these taxonomists have – much of which is not captured in manuscripts or books – is transferred to the next generation. The Deep-Sea Coral Taxonomy Workshop, funded by a Lounsbery award from the Deep-Sea Biology Society, aimed to provide a training opportunities and build taxonomic capacity in Colombia and Latin America. Workshop participants examined the deep-sea coral diversity of the southern western Caribbean, a poorly explored region. The three-day workshop was based mainly on hands-on activities focused on octocorals and black corals, and included introductory talks to the taxonomy of these groups and identification activities using specimens. Thanks to the workshop, it was possible to review and update the classification database of the Makuriwa Marine Natural History Museum collection. Additionally, four new species from the families Clavulariidae, Plexauridae and Gorgoniidae were identified and will be described in the near future.
