Abstract
BackgroundThe checklist of Porifera of Greece was created in the framework of the Greek Taxon Information System (GTIS), an initiative of the LifeWatchGreece Research Infrastructure (ESFRI) that has resumed efforts to compile a complete checklist of species recorded from Greece. An updated checklist of Porifera was created on the basis of a list of the Aegean Demospongiae and Homoscleromorpha published one decade ago. All records of species known to occur in Greek waters were taxonomically validated and cross-checked for possible inaccuracies and omissions. Then, all recent publications were reviewed and the species recorded from 2006 to date were added to the list.New informationThe updated checklist of Porifera of Greece comprises 215 species, classified to 111 genera, 65 families, 24 orders, and 4 classes. In total, 34 new additions were made to the previous species list (8 Calcarea, 17 Demospongiae, 1 Hexactinellida, and 6 Homoscleromorpha) with Calcarea being listed for the first time from the area. The demosponge orders Poecilosclerida, Dictyoceratida, Tetractinellida, Haplosclerida, and Suberitida have the highest number of species covering 62% of the known Greek sponge species richness. It is worth mentioning that 8 species have been first described from Greek waters, 7 of which are considered endemic to this area. Our bibliographic overview also revealed knowledge gaps with regard to specific habitats typically rich in sponge diversity, and marine sectors of Greece.
Highlights
The history of sponge science is directly linked to Greek civilization, since the older written references to sponges are found in Homer’s Epics, and their scientific knowledge has been established by the Greek philosopher, and first marine biologist, Aristotle in his zoological works (Voultsiadou 2007).In modern times, research on Porifera of the Greek seas started early in the 20th century with the study of bath sponges, i.e., the members of the family Spongiidae (Szymanski 1904, Arndt 1937)

The Checklist of Porifera of Greece (Suppl. material 1) was created in the framework of the Greek Taxon Information System (GTIS), an initiative of the LifeWatchGreece Research Infrastructure (ESFRI) that has resumed efforts to compile a complete checklist of all species reported from Greece (Bailly et al 2016)
Summary
The history of sponge science is directly linked to Greek civilization, since the older written references to sponges are found in Homer’s Epics, and their scientific knowledge has been established by the Greek philosopher, and first marine biologist, Aristotle in his zoological works (Voultsiadou 2007).In modern times, research on Porifera of the Greek seas started early in the 20th century with the study of bath sponges, i.e., the members of the family Spongiidae (Szymanski 1904, Arndt 1937). The systematic research on Greek Porifera started in the 1990s when the Laboratory of Zoology, Aristotle University of Thessaloniki, presented a series of publications on the Aegean sponge taxonomy, ecology and biogeography. New species were described (Voultsiadou-Koukoura and van Soest 1991a, Voultsiadou-Koukoura and van Soest 1991b, Voultsiadou-Koukoura et al 1991), species lists presented (Voultsiadou-Koukoura and Koukouras 1993, Voultsiadou-Koukoura and van Soest 1993), and the associations of sponges with other invertebrates investigated (Koukouras et al 1996 and references therein). The checklist of Porifera of Greece was created in the framework of the Greek Taxon Information System (GTIS), an initiative of the LifeWatchGreece Research Infrastructure (ESFRI) that has resumed efforts to compile a complete checklist of species recorded from Greece.
