Between the 10th and the 15th of September, four generations of sponge researchers gathered in Marseille to advance our knowledge of the taxonomy (and history, and biology) of Atlanto-Mediterranean deep-sea and cave sponges. The workshop also paved the way for the release of a new Zootaxa volume on “Deep-Sea & Cave Sponges” in honor of Jean Vacelet and Klaus Rützler to celebrate the publication, sixty years ago, of the first works on the biodiversity of marine caves (Laborel & Vacelet 1958; Russ & Rützler 1959).
The volume is co-edited by SponGES’ team member Paco Cárdenas, who also attended the workshop. Further SponGES members in Marseille included Javier Cristobo and Pilar Rios. Pilar, Cristobo and Paco are also authoring three papers in the Zootaxa volume:
